Gravitational Wave S6 Directed Search (CasA) ending
We are nearing the end of the "S66CasA GW run". This means that only relatively few tasks of possibly remote frequency bands are available for this application, possibly resulting in an increased download volume per task. If you want to avoid this, you may opt-out of the "Gravitational Wave S6 Directed Search (CasA)" search in your Einstein@Home preferences on the web site.

Gravitational Wave search GPU App version
Due to the excellent work of our French volunteer Christophe Choquet we finally have a working OpenCL version of the Gravitational Wave search ("S6CasA") application. Thank you Christophe!

This App version is currently considered 'Beta' and being tested on Einstein@Home. To participate in the Beta test, you need to edit your Einstein@Home preferences, and set "Run beta/test application versions?" to "yes".

It is currently available for Windows (32 Bit) and Linux (64 Bit) only, and you should have a card which supports double precision FP in hardware.

Einstein@Home Volunteers Discover Four "Young" Gamma-Ray Pulsars
Congratulations to our volunteers:

Thomas M. Jackson, Kentucky, USA
Mak-ino, Japan
Doug Lean, Australia
Hans-Peter Tobler, Germany
NEMO computing cluster, UW-Milwaukee, USA
Chen, USA
David Z, Canada
Test, France

whose computers have found 4 new gamma-ray pulsars in data from the Large Area Telescope on board NASA's Fermi Satellite. These are the first gamma-ray pulsars ever discovered by Einstein@Home; only a few dozen such objects (spinning neutron stars whose pulsations are only visible via their gamma rays) are known.

The scientific paper is available here (use PDF link on the top right-hand side) and will be published in the next hours in the Astrophysical Journal Letters. If you are interested in learning more, a press release and other materials concerning the discovery are also available on-line.

Many thanks to all Einstein@Home volunteers, whose computers have made these exciting discoveries possible!

Einstein@home downtime
Einstein@Home will be shutdown several hours today to fix a filesystem problem. 18 Jul 2013 19:40:31 UTC · Comment


Gravitational Wave S6 Directed Search (CasA) launched
After a pause of about two weeks Einstein@Home is searching for gravitational waves again. The new search application is called "Gravitational Wave S6 Directed Search (CasA)". It is the first "directed" search performed by Einstein@Home, targeting only at a single direction in the sky ("Cassiopeia A").

This search uses new data files, so be prepared for a larger initial download (>100MB).
17 Jul 2013 9:24:07 UTC · Comment


Gravitational Wave S6 LineVeto search (extended) ending
Einstein@Home is slowly but steadily finishing the current Gravitational Wave search. The data used for this search will not be re-used for subsequent searches. This means that our "locality scheduling" won't be as effective as before to keep the download volume low. In this finishing phase you may receive tasks that require you to download 100MB or more to process. If you don't want this to happen, you may suspend the Einstein@Home project for a week or opt-out of that application in your EInstein@Home preferences (on "your account" page).

Syracuse University rises to the top!
Thank you and congratulations to Syracuse University whose recent average credit value in excess of 3 million is one of the largest that we have seen in the project's history. This represents about 4% of Einstein@Home's total computing power. There must be a lot of Syracuse University campus computers crunching Einstein@Home! Without your help a few weeks ago, I don't think we wouldn't have made it past the 1 Petaflop mark.

Einstein@Home passes 1 Petaflop of computing power!
Congratulations and thank you to all Einstein@Home volunteers: sometime shortly after January 1st 2013, Einstein@Home passed the 1 Petaflop computing-power barrier. To put this in context, according to the current (November 2012) Top-500 computing list, there are only 23 computers on our planet that deliver this much computing power.

(One Petaflop is 1,000,000,000,000,000 floating point operations per second.)

Congratulations and thank you again, and keep on crunching!

Can Einstein@Home pass the 1 Petaflop (1000 Teraflop) barrier?
The computing power of Einstein@Home has exceeded 950 Teraflops for the first time since the project was begun in 2005. Based on the rate that our computing power has been growing, I am hopeful that Einstein@Home will pass the 1 Petaflop barrier before the end of 2012.

Unplanned downtime Nov 17th
There was a scheduled power outage of UWM’s physics building for November 17 but since we did not expect any disruption to the E@H servers we did not announce any downtime. The plan was to run E@H off of the data center’s UPS but unfortunately the batteries did not last nearly as long as expected. We apologize for any inconvenience caused by this outage.

Results of Einstein@Home Search for Gravitational Waves in Full LIGO S5 Data Set Available
After several years of analysis and post-processing work, the results of the Einstein@Home search for gravitational waves in the full LIGO S5 data set are now publicly available. The paper can be found here http://arxiv.org/abs/1207.7176.

The results are negative: no statistically-significant gravitational wave signals have been detected. However the search excluded signals with a greater level of sensitivity than previously achieved. For example, in the 0.5 Hz-wide band at 152.5 Hz, signals with intrinsic strain h0 greater than 7.6e-25 are excluded with 90% confidence.

Einstein@Home will continue to search for gravitational-wave signals. In the long term, we are optimistic. The LIGO and VIRGO and GEO detectors are all undergoing hardware upgrades to improve their sensitivity, and Einstein@Home will continue to develop and employ better and more sensitive data analysis methods.

Einstein@Home GPU Application for ATI/AMD Graphics Cards
After more than a year of work by Oliver Bock, Bernd Machenschalk, Heinz-Bernd Eggenstein and other developers, we are pleased to announce the release of the first Einstein@Home application for ATI/AMD Graphics Cards.

This OpenCL application, which searches Arecibo data for new radio pulsars, is about a factor of ten faster than the same search running on a typical CPU. The application is currently available for Windows and Linux computers with Radeon HD 5000 or better graphics cards. We hope to have a version for Macintosh (Apple OS X 10.8, Mountain Lion) sometime this summer, but there are still some problems that need to be fixed or worked around.

Volunteers who wish to run this application will need to install version 7.0.27 or later of the BOINC client. Please see this thread for more information, or if you want to ask questions.

Many thanks to the AMD/ATI team for their support in the OpenCL software development effort.

Application changes
Our Gravitational Wave search "S6Bucket" is nearing its end. As usual while processing the last tasks of a run, locality scheduling isn't very effective, and the download volume increases. People with a slow (or expensive) internet connection may want to back off from Einstein@Home for a few days.

The next Gravitational Wave search "S6LV1" is already set up, we expect to ship the first tasks of that search in the next few days.

In the past days we also started shipping a new version of the Radio Pulsar search application (BRP4). This is in preparation for using a new data file format which should reduce the data (download) volume of a BRP4 task to about a half.

Participants using 'anonymous platform' (app_info.xml) need to update their application setup.

Please refer to our Technical News message board for details and updates about these applications.

Einstein@Home starts processing Arecibo "Mock" data
We have finished generating the last workunits for the Einstein@Home search of the Parkes Multi-Beam Pulsar Survey (PMPS) data set. This search should wind up in the coming weeks as these final workunits are processed by our volunteers. The Einstein@Home PMPS search has already found five new radio pulsars, and we hope that there are still a few more waiting to be found.

Today we launched the first "Binary Radio Pulsar" (BRP4) workunits, which are searching fresh radio data from the Arecibo Observatory. This data has been obtained at Arecibo using a new wideband back-end spectrometer, named after its creator Jeff Mock. The Arecibo data previously processed on Einstein@Home was acquired using the "WAPP" back-end, which has a 100 MHz bandwidth in 256 channels. The new Mock data which we are starting to process today has a 300 MHz bandwidth in 1024 channels. This will permit deeper and more sensitive Arecibo searches than ever before.

Our LIGO/GEO Colleagues at the University of Birmingham have just released a free and fun interactive computer game called "Space-Time Quest". It is available from this web site. There is also a one-minute YouTube trailer describing the game, which involves designing, building and operating a modern gravitational-wave detector on a fixed 100-million-pound budget. 10 Mar 2011 13:14:33 UTC · Comment


Einstein@Home Discovers New Binary Radio Pulsar
A new preprint reports the second Einstein@Home discovery, of a radio pulsar orbiting a white dwarf star once every 9.4 hours. The pulsar, called J1952+2630, is spinning on its axis 48 times per second. It was discovered in data collected at Arecibo Observatory in 2005 by the PALFA Collaboration. The white-dwarf companion star is unusually massive, and weighs at least 95% as much as our sun. This means that J1952+2630 probably belongs to a rare class of intermediate-mass binary pulsars (five were previously known).

The "discovery plots" can be seen near the top of the Einstein@Home (re)detection page.

Congratulations to the two Einstein@Home participants whose computers found J1952+2630 with the highest significance: Dr. Vitaliy V. Shiryaev (Moscow, Russia) and Stacey Eastham (Darwen, UK)! And a big "thank you" to all Einstein@Home volunteers, whose continuing support makes these exciting discoveries possible.

New Einstein@Home Radio Pulsar Search and NVIDIA GPU Code
Einstein@Home is beginning a new round of searching for radio pulsars in short-orbital-period binary systems.



This is accompanied by the release of a new application (called BRP3). The new application is particularly efficient on NVIDIA Graphics Processor Cards (up to a factor of 20 faster than the CPU-only application). In addition, when running on an NVIDIA GPU card, this new application makes very little use of the CPU (typically around 20% CPU use when the GPU is devoted to Einstein@Home).

The NVIDIA GPU application is initially available for Windows and Linux only. We hope to have a Macintosh version available soon. Due to limitations in the NVIDIA drivers, the Linux version still makes heavy use of the CPU. This will be fixed in Spring 2011, when a new version of the NVIDIA Driver is released. Many thanks to NVIDIA technical support for their assistance!

Because we have exhausted the backlog of data from Arecibo Observatory, this new application is being shipped with data from the Parkes Multibeam Pulsar Survey (from the Parkes Radio Telescope in Australia). In the next weeks we expect to also start using this new application on fresh Arecibo data taken with the latest 'Mock Spectrometer' back-end.

Questions, problems or bug reports related to this new application and search should be reported in this news item thread as a 'Comment'.

Validation Errors in ABP Workunits
A recent modification to ABP workunit generation (bundling 10 dispersion measures into a single workunit) has caused all these new workunits to fail with validation errors. We have fixed the mistake, and have been sending out corrected ABP work since 14:20 UTC, October 2nd. In order to use and give credits for the work which (incorrectly) generated validation errors, the automatic validation of incoming results has been temporarily halted. Validation will be done manually, once per day, for (roughly) the next two weeks. 2 Oct 2010 16:44:02 UTC · Comment

First Einstein@Home Discovery!
We are delighted to announce that Einstein@Home has made its first discovery: a radio pulsar, found in data from the Arecibo Observatory in Puerto Rico.

Details are available in a paper published online by Science today. Science has given us permission to post a copy of the abstract and paper here. They are also on the Science website here. The manuscript is also in the arXiv preprint archive (use the PDF link in the top right corner).

A press-conference webcast about this first discovery is also available.

The name of the pulsar is PSR J2007+2722. It is a 40.8 Hz isolated pulsar, 17,000 light years distant in the plane of the Galaxy, and is most likely a Disrupted Recycled Pulsar (DRP). If so, it is the fastest DRP yet discovered.

The Einstein@Home volunteers whose computers found the pulsar with the highest significance are Chris and Helen Colvin, from Ames Iowa and Daniel Gebhardt, Musikinformatik, Universitaet Mainz.

Additional information about the discovery is available on our web pages. I will also talk about it at the London Citizen Cyberscience Summit on September 2nd.

We thank ALL Einstein@Home volunteers for their support, and look forward eagerly to our next discovery.

We started shipping the first S5GC1 work. 7 May 2010 0:00:00 UTC · Comment


In transition to the S5GC1 run, we're currently sending out the rest of S5GCE tasks without locality scheduling. This leads to additional transfer volume on both the client and the server side. If you care about data volume or have a slow internet connection, you should suspend Einstein@Home for a few hours or days. Our download mirrors are currently overloaded. We hope that things will be back to normal once we start shipping out S5GC1 work hopefully in less than an hour. 7 May 2010 0:00:00 UTC · Comment


In preparation of the S5GC1 run, which should start at the end of the week, we switched off sending deletion requests for S5GCE data files to the clients. This is to prevent clients from having to download them again for the new, saving bandwidth on both client and server side. 4 May 2010 0:00:00 UTC · Comment

Work is now being sent out for the new S5GCE run. Your clients may have a difficult time downloading new work for the next day or so as a result of the download mirrors being overloaded. 19 Mar 2010 0:00:00 UTC · Comment


We need to briefly shut down the project for a database update. This will happen about 16:00 UTC March 17 and should last about an hour. 17 Mar 2010 0:00:00 UTC · Comment


The S5R6 run is nearing its end, and there are only a few tasks left that will not necessarily match the data files already on the clients. This results in an increased download volume per task for the remaining S5R6 ones. Also too we expect an increased data volume per CPU hour at the beginning of the upcoming S5GCE run. Participants on slow internet connections might want to suspend the project for a few days or weeks. 17 Mar 2010 0:00:00 UTC · Comment

Our database is currently pretty slow, due to a large number of ABP2 results. We are taking measures to keep the project running, but with a few restrictions: The scheduler (task sending and reporting) is disabled part of the time (clients will see a 'temporarily down for maintenance' message). The server status page has been disabled. We'll also reduce the time results are kept in the database. Hopefully we will be able to return to normal operation in a few days. 1 Feb 2010 0:00:00 UTC · Comment

The Arecibo Binary Pulsar search is undergoing a major transition. We expect clients to not get ABP1 tasks for a while, then, if all goes well, tasks for a new application called ABP2. Read more about this here. 6 Jan 2010 0:00:00 UTC · Comment


You may have noticed that the E@H server has been a bit slow over the last 12 hours. There was a bad entry in the database that was causing problems for the transitioner. The project should be more reponsive now. 30 Dec 2009 0:00:00 UTC · Comment


Additionally a network switch died. Bad luck. The switch had been replaced. The project should be back after a DB dump. 10 Dec 2009 0:00:00 UTC · Comment


Parts of the project were taken offline for some cleanup necessary to fix the recent scheduler http problems. We hoped that this could be done within minutes and thus remain unnoticed for most users, but it looks like it will take another hour or two until the scheduler is running again. 10 Dec 2009 0:00:00 UTC · Comment

The Einstein@Home project is finally back up and running properly. The binary radio pulsar search may not be sending out new work for a couple of more days while we fix some VPN problems between the WU generator in Hannover and the project database in Milwaukee. However the S5R5 gravitational-wave search IS sending out plenty of work. Many thanks again to our loyal volunteers and contributors for their patience! 24 Apr 2009 0:00:00 UTC · Comment


We have completed the database maintenance and are restarting the Einstein@Home project. Hopefully this will go well, but please be patient as it may take some time before everything is working smoothly again. We are advancing the reporting deadlines for work in progress by 10 days, so that work already completed is not marked as unreturned. Because of the work on the database, contributors will NOT be able to see the status of work that was already completed in the past. However in the future, as before, contributors WILL be able to track this status. No contributor credits have been forgotten or lost. 24 Apr 2009 0:00:00 UTC · Comment


The database is still purging, at a rate of about 400,000 workunits per day. We expect that this process will be completed by about 06:00 UTC tomorrow. At that time, we will do some additional database maintenance (table optimization) and then restart the project. So in total about another 24 hours will still be needed to bring everything back to normal. Thanks again for your patience during this unfortunate and long outage. 23 Apr 2009 0:00:00 UTC · Comment


We think we have found a simple fix for the database problems. The database has grown to 45 GB in size and has gotten too large for the physical memory of the machine that hosts it. However it turns out that due to some mistakes made in the project operations during the past weeks, about 80% of the work in the database is already completed. So we are running a db_purge task tonight that should remove this already-completed work from the database, leaving only the work-in-progress still in place in the database. If this is successful, then Einstein@Home should be back up and operating normally in about another 24 hours. Thank you for your patience! 22 Apr 2009 0:00:00 UTC · Comment


The daemons worked through the backlog last night, but turning on the scheduler this morning for a few hours brought the DB down again. Some of the problems have been identified and fixed or worked around, but we are still working on some issues. The project has been shut down again for some DB analyis runs, it will probably be up and down again a number of times today as we fix the remaining issues one by one. 21 Apr 2009 0:00:00 UTC · Comment


We still have serious problems with our database and are working on it. For the moment we disabled the scheduler to let the rest of the daemons work through the backlogs, i.e. no work is sent out or can be reported. 20 Apr 2009 0:00:00 UTC · Comment

We have completed processing the S5R3 workunits. S5R3 was the first search using the combined F-stat plus Hough method, which is currently the most sensitive search technique that is known. This search used approximately one year of data from LIGO's first science run (S5) at design sensitivity. The S5R3 post-processing is being led by Dr. Maria Alessandra Papa, one of the inventors of the search technique. 25 Sep 2008 0:00:00 UTC · Comment


The server upgrade is mostly complete, and we are now distributing work for our new search, S5R4a. If your personal BOINC installation has behaved strangely in the past days, please be patient. In most cases this will now sort itself out.

We are reaching the end of the current analysis run and expect the last workunits of S5R3 to be generated around Aug 1. Participants will probably experience an increase of the downloads necessary for the remaining S5R3 workunits to be processed. Users with low bandwidth will probably want to suspend the project for some days. Users of Beta- and Power-Apps should be aware that they will not get tasks of the upcomig S5R4 run with these S5R3 Apps. 22 Jul 2008 0:00:00 UTC · Comment

We found that we need to split the current S5R3 run at 800 Hz frequency (read more about it in this forum thread). We are currently ~6 days away from the end of the lower half, which means that we are experiencing the usual workunit-cleanup at the end of a run, with the common raise of downlaod traffic during that time.

The S5 science run, whose goal was to accumulate one year of triple-coincident data at LIGO design sensitivity, officially ended at 00:00 UTC October 1, 2007. This completes the data-taking stage of a project which was officially begun in 1992 by Kip Thorne, Ron Drever, and Rainer Weiss. LIGO will now undergo two planned upgrades to improve sensitivity. The first of these upgrades (Enhanced LIGO) will be followed by the S6 science run, anticipated for 2009. Einstein@Home is now busy searching the S5 data set. The Einstein@Home S4 postprocessing and analysis are largely complete and under review by the LIGO Scientific Collaboration. We hope to provide updates about these results before the end of this year. 2 Oct 2007 0:00:00 UTC · Comment

The repairs described yesterday are still underway. We will have frequent and unscheduled service interruptions while we continue work on this today. 22 Feb 2007 0:00:00 UTC · Comment


The database problems have been identified but in order to correct them some modifications will be needed on the Einstein@Home back-end components. To effect these modifications, the project will have to be repeatedly taken up and down today. So please be warned: we will have frequent and unscheduled service interruptions while we work on this today. 21 Feb 2007 0:00:00 UTC · Comment


Einstein@Home has been having serious problems with database server load. We are working hard to try and find the source of the problem. You will likely continue to have problems connecting to the project and may get messages like "project down" or similar until we fix the problems at our end. Your patience and support of the project is greatly appreciated and we will try to do a better job of keeping you informed about the status of the project in the future. 20 Feb 2007 0:00:00 UTC · Comment


The Einstein@Home project was offline today due to a server crash. There was a kernel panic on fileserver that is unrelated to previous problems we have had with the fileservers. 24 Jan 2007 0:00:00 UTC · Comment


A couple of days ago Einstein@Home issued the last workunits from our first search of LIGO S5 data. The post-processing of these results will begin in a few weeks when the last result from these workunits is returned. Meanwhile we are gearing up to begin a new type of more sensitive search (called a hierarchical search). Unfortunately this is not yet ready. In the meantime we are extending the first S5 search to a larger range of spin-down ages than previously. We apologize for some problems that occured in the last few days as we finished one search and started another. We are still coping with some hardware problems, which complicated the transition. For further details please see this message board thread. 19 Jan 2006 0:00:00 UTC · Comment


The Einstein@Home project was down for the last few days because of the continuing fileserver problems. Another server has been put in place for the primary fileserver and we hope this temporary solution will be stable. 7 Jan 2006 0:00:00 UTC · Comment

We had another unplanned outage today (approximately one hour) because power was disconnected from our UPS systems for too long. The project is back up and running normally. 2 Jun 2006 0:00:00 UTC · Comment


Thank you for your patience: Einstein@Home is now running normally again. Over the weekend some additional construction/repair work will be done. This work has been planned so as not to interfere with the project. However if something does go wrong we may be 'off the air' again, at least briefly. We will try hard to prevent this from happening. 1 Jun 2006 0:00:00 UTC · Comment


Einstein@Home is back up and running. Because of the backlog of work that has been completed by YOUR computers in the past few days, our systems may be somewhat slow at uploading this completed work and handing out new work. So please be patient if it takes a bit of time before your computers are busy crunching away! Note: experience shows that recovery from this type of 'hard' failure can take some time; there may be new problems that appear, which may require rapid shut-down and additional corrective action at our end. But we will try hard to avoid this if possible. 31 May 2006 0:00:00 UTC · Comment


We are making good progress in restarting the project. Now that the web pages are up, we will first enable file uploads and then enable the scheduler. It may be some hours before we are again handing out new work and everything is functioning normally. We'll post further reports here when we have more news. 31 May 2006 0:00:00 UTC · Comment

The Einstein@Home validator ran into an unknown problem at 07:21 UTC May 11 and started marking all results as 'validate error' until the validator was restarted at about 15:00 UTC May 11. It is our intent to grant the canonical credit to all results marked as 'validate error' during that period. This may take some time as we need to wait until a canonical result is found for each workunit. So this credit will be awarded gradually over the coming few days. 11 May 2006 0:00:00 UTC · Comment


The Einstein@Home project was down for a couple hours today due to a hardware failure in the primary database server. The failure occurred some time after 18:00 UTC on April 23 and the project was running again by 20:30 UTC.

The Einstein@Home project was down again for several hours today due to a loss of power to the E@H servers. The problem started at 01:05 UTC on April 15th. The current situation is that there is a faulty 150A breaker for server room where E@H is located. We are now only running the most essential servers in order to decrease the load until the breaker can be replaced. 15 Apr 2006 0:00:00 UTC · Comment

Einstein@Home will briefly be taken offline while changes are made to the database server. The maintenance will start at 05:00 UTC March 15 and will last approximately 2 hours. 15 Mar 2006 0:00:00 UTC · Comment


The addition of 16GB of memory to the database server caused an unexpected problem. It exposed a bug in the 3ware Linux disk controller driver which took many hours to identify and understand. The project was back up and running soon after 13:00 UTC today. We do not anticipate any further issues, and apologize to project participants for the unanticipated downtime. On the positive side, the memory upgrade will make the Einstein@Home web pages and project forums snappier and more responsive. 5 Mar 2006 0:00:00 UTC · Comment

There was a disk failure in the Einstein@Home project server on February 17 at 20:47:08 UTC which was handled correctly by the RAID controller hardware but not by the OS driver, resulting in an unwritable file system. This was fixed by David Hammer within about five hours. During this time, file uploads and downloads were not possible. About two hours after the disk was replaced and the file systems was repaired, a bit of fussing was also needed to restart work unit generation and the scheduler. The project is now up and running again. There was no data loss or corruption and we do not expect any further issues. Note that this was our first project downtime in approximately 8 months. 18 Feb 2006 0:00:00 UTC · Comment

We have finished the first complete analysis of the LIGO S3 data set. Based on this, the data preparation and cleaning process have been modified to remove a number of instrumental artifacts that appeared in the post-processing stage, and a new data set has been prepared.

Some additional 'paranoia checks' added into the 4.75-4.77 applications identified an important bug in the central LALDemod() routine of the analysis code. (PoorBoy: your lost workunits were not in vain!). The maximum velocity of our detector (as the earth orbits the sun and rotates on its axis) is about 1% larger than the code allowed for, so for certain data sets and sky directions, a frequency array was one bin smaller than required. This has been fixed, and new applications (4.78, 4.79, 4.80) are now being distributed. 11 Feb 2005 0:00:00 UTC · Comment


New applications are now available for Windows (4.75) Linux (4.76) and Mac (4.77). These should resolve the 'hanging workunit' problems described below. They also incorporate several other fixes and improvements.

We have started using a mirrored download server at the Albert Einstein Institute (AEI) in Golm bei Potsdam, near Berlin, Germany. Hosts whose timezone offset from UTC is closer to UWM (UTC-7 hours) will continue to get data and executables from UWM. Those hosts whose offset from UTC is closer to the AEI (UTC+1 hour) will get data and executables from AEI. This should give faster and more reliable downloads for everyone. Note that if a download fails from the first server, the alternate will also be tried. Please report any problems or strange behavior to the message boards. 1 Feb 2005 0:00:00 UTC · Comment


We are now testing the new 'coincidence' routine. This has reduced the run time of the coincidence step in the worst-case tests from about six hours to four minutes, and memory use by a significant factor. If all goes well, new applications should be available this week. We are also now testing a modified scheduler that (1) provides better feedback messages to hosts that are not getting work because they lack disk space, and (2) deletes data files from hosts when they run short of disk space. 31 Jan 2005 0:00:00 UTC · Comment


Thanks in part to user feedback and detective work by Bernd Machenschalk and others we have located and are now fixing a significant bug in our search code. The search code works in three stages. The first two stages search instrument data from two different periods of time. The third stage searches for consistency (coincidence) in the output from these two time periods. The bug is in this final third stage. For a few of the input data sets, this third coincidence step (which should take only a minute or so) takes much longer because the computation time increases from N log N to order N-squared. The results are still correct but the computation can last for hours. Xavier Siemens is rewriting this routine to guarantee N log N behavior; we hope to have a revised application ready for testing within a few days. 26 Jan 2005 0:00:00 UTC · Comment


Version 4.19 of the BOINC client has been released. Rom has made this release the default boinc client and not just a development version. Please upgrade to 4.19 as soon as possible. 26 Jan 2005 0:00:00 UTC · Comment


Version 4.18 of the BOINC client has been released. The most important bug that was fixed is.

- When the server requests a delay, make sure we do not overwrite the min_rpc_time, which has already been set to the proper delay time.
This was a bug that was reported by Bruce. Please upgrade to 4.18 as soon as possible. 25 Jan 2005 0:00:00 UTC · Comment

Version 4.17 of the BOINC client has been released. Here is what Rom said in the release notes.

We have released what we believe is going to be a build good enough for public release. Let us know if there is anything wrong, if not, we'll be releasing soon. ----- Rom
Please upgrade to 4.17 as soon as possible. 24 Jan 2005 0:00:00 UTC · Comment

The BOINC developers have once again released a new version of the client (4.16) that fixes two bugs. Here is what Rom said in the release notes.

This release contains two fixes: - don't unsuspend tasks before restarting them - allow large command lines (backpatched from 4.5x) ----- Rom
Please upgrade to 4.16 as soon as possible. 20 Jan 2005 0:00:00 UTC · Comment

We are testing the new "monolithic fast validator", which is needed for us to accomodate much larger numbers of users. Our apologies: a bug in this caused a handful of successful and correct results to be marked as "invalid". 20 Jan 2005 0:00:00 UTC · Comment


The BOINC developers have released a new version of the client (4.15) that fixes a bug that caused some lost work for CPDN users when they were upgrading the client. Please upgrade to 4.15 as soon as possible. 18 Jan 2005 0:00:00 UTC · Comment


We have cancelled the remaining "old scheduler" workunits, and started testing the new locality scheduler. This should send work to hosts that already have the correct data input files, greatly reducing the download demands on host computers and the Einstein@Home server. 18 Jan 2005 0:00:00 UTC · Comment


As explained in the news item from Jan 13, below, the BOINC 4.13 core client contained a serious bug that has now been fixed. Einstein@Home users: please upgrade to the BOINC 4.14 core client, which can be found halfway down this page. PLEASE UPGRADE THE BOINC CORE CLIENT TO VERSION 4.14. THIS WILL BECOME MANDATORY FOR EINSTEIN@HOME WITHIN A SHORT TIME. 17 Jan 2005 0:00:00 UTC · Comment


To prepare for the upgrade of our scheduler, we are not providing new work for the next day or two. We are taking this measure to try and minimize the amount of lost credit and to make the transition to the new scheduler as smooth as possible. 14 Jan 2005 0:00:00 UTC · Comment


IMPORTANT NEWS: David Anderson, the creator of BOINC, has found and fixed a serious bug in the BOINC 'core client'. This causes failure of a job if the download of any of its input files fails (the correct behavior is to retry and complete the download, then run the job). Moreover, any other job that used the same files would also fail. A fixed core client should be available soon. This should make Einstein@Home work much better and eliminate the main source of job failure 13 Jan 2005 0:00:00 UTC · Comment


In the next several days we are going to shift from using the current BOINC scheduler to a new BOINC 'locality' scheduler. This will have some important benefits. In particular, it will ensure that host computers get lots of work for the (large) data files that they have already downloaded, instead of being required to download a new large data file for each new item of work. It will also remove these large data files from the host computers when they are no longer needed. Unfortunately the new scheduler is not compatible with the test workunits currently in progress on many hosts. Testers, please note that for this reason, we will be forced to cancel a number of workunits currently in progress, when we shift to the new scheduler. 12 Jan 2005 0:00:00 UTC · Comment


In anticipation of 'going public' Einstein@Home is now running on the new server hardware. We need to complete and test (hopefully) one final round of application revisions before this happens. Hopefully this will eliminate the remaining problems with SIGABORT failures in the Linux application and similar problems (and a useless docked window) in the Macintosh application. 4 Jan 2005 0:00:00 UTC · Comment


Important News! The Einstein@Home server will be SHUT DOWN a ~9:30 UTC on WED JAN 4 so we can upgrade to new hardware 3 Jan 2005 0:00:00 UTC · Comment


HAPPY NEW YEAR! We are starting to distribute our final test workunits, named "pt11". These take substantially longer than our previous test workunits. We expect to have our new server hardware in place within a few days, for out public launch. To all of our testers, thank you for making this possible, and please be patient if things don't work quite right for the next few days. 31 Dec 2004 0:00:00 UTC · Comment


Note that the Einstein@Home server will be up and down and possibly unstable during the coming week, as we install new hardware and prepare to go public. Also, we will soon start providing new workunits that take 12 times as long to execute as the current test workunits. 27 Dec 2004 0:00:00 UTC · Comment


New Windows, Linux and Mac applications are available. All compress upload data to save bandwidth. Mac: resume-bug fixed. Linux: Should work correctly on both graphics and non-graphics capable machines; fixed bug that caused user-specified checkpoint interval to be ignored. 27 Dec 2004 0:00:00 UTC · Comment


New Windows application is available. This fixes the problem that the application was checkpointing (writing to disk) more often than was requested by the user's preferences. 10 Dec 2004 0:00:00 UTC · Comment


New Mac OSX application is available. In the next few days we'll distribute a small tool to pop open the screensaver graphics window for this. Note that this is our first app version to compress its upload files (typical compression factor > 3). The next Linux and Windows apps will also do this. 2 Dec 2004 0:00:00 UTC · Comment


We have begun an ongoing process of purging the workunit/result database of completed workunits and results. This makes the 'back end' of Einstein@Home much faster, but it means that the lists of results and workunits shown under 'Your account' won't list workunits that have been completed, since these are purged from the database. 1 Dec 2004 0:00:00 UTC · Comment


New Mac OSX executable is now being tested. It is a factor of 2.5 faster than the previous version, and it displays the screensaver graphics! 26 Nov 2004 0:00:00 UTC · Comment


New Windows executable (4.46) fixes problem with distorted search point marker. New Linux/Mac OSX executables coming soon. 23 Nov 2004 0:00:00 UTC · Comment


A bug in BOINC, and a mistake in our build process, caused us to post broken Windows and Linux executables this weekend. We have now posted repaired and faster Linux (4.43) and Windows (4.44) executables. 21 Nov 2004 0:00:00 UTC · Comment


Cross Project ID's should now work (thanks, Jens!) 19 Nov 2004 0:00:00 UTC · Comment
