1) Message boards : Problems and Bug Reports : Not getting new work - scheduler log message (Message 138008)
Posted 1 day ago by Richard Haselgrove
For the past three weeks, I have not received any work for this project. My error log contains the following message each time an attempt is made:

29/01/2015 9:51:13 PM | Einstein@Home | see scheduler log messages on http://einstein5.aei.uni-hannover.de/EinsteinAtHome/host_sched_logs/3596/3596493

I have looked at this, but it makes no sense to me. Can someone else interpret it? Is it my problem, or the project's problem?

Thanks.
Geoffrey

You are only requesting work for your GPU:

2015-01-29 10:51:12.0071 [PID=26860] [send] CPU: req 0.00 sec, 0.00 instances; est delay 0.00
2015-01-29 10:51:12.0071 [PID=26860] [send] CUDA: req 108000.00 sec, 1.00 instances; est delay 0.00

That's your NVIDIA GeForce GT 220 - quite an old video card now, but it should still be useful to this project.

The real problem is

2015-01-29 10:51:12.3373 [PID=26860] [version] CUDA version required min: 3020, supplied: 3010

- that should be solved by updating your video driver. Visit

http://www.nvidia.com/Download/Find.aspx?lang=en-us

and follow the instructions. With that video card, I'd avoid the very latest (version 340.52) driver, but earlier WHQL drivers like 337.88 should be fine.

Yup, that's done it - data flowing in both directions now (old work reported, and new work assigned/downloaded/running). Time for beer!

So am I. It's unusual to see a BOINC Scheduler take this long to reach working temperature, or whichever simile you prefer to use.

Well I can't get to connect either,
Logs show:-

28/01/2015 17:15:45 | Einstein@Home | Scheduler request failed: Couldn't connect to server
28/01/2015 17:15:58 | | Project communication failed: attempting access to reference site
28/01/2015 17:15:59 | | Internet access OK - project servers may be temporarily down.

So there is some sort of comms failure.

Regards,

Cliff, could you switch to today's thread, please?

Fixed!

Yes, uploads accepted at normal speed without problems - thanks.

But I'm still getting

28/01/2015 16:24:24 | Einstein@Home | Scheduler request failed: Couldn't connect to server

when I try to report them - that can be a simple 'too busy' in the early stages after a restart - or it might not be.

So straight up. Is E@H back online or not?

It's back online.
9) Message boards : Problems and Bug Reports : Update to 7.4.36 Fails (Message 137811)
Posted 8 days ago by Richard Haselgrove
Are you using the Boinc defaults when you install or are you making some changes? Are you trying to do a 'service' install? Are you trying to install Boinc with 'vbox'? Did you choose the 64 bit version to try and install?

Upon trying to re-install 7.2.42 I am now getting a message "Error 1324. The path IONE??? contains an invalid character" and then the install wizard fails.

You will probably need to use Regedit to clean up the path name(s) in

HKEY_LOCAL_MACHINE\SOFTWARE\Space Sciences Laboratory, U.C. Berkeley\BOINC Setup

or simply delete the whole 'BOINC setup' registry key and start fresh - do check the settings carefully, and make sure they suit your environment, as you go through the re-install after that.
10) Message boards : Problems and Bug Reports : Einstein@Home GPU/APU Application for AMD/ATI Graphics Cards: discussion thread (Message 137808)
Posted 8 days ago by Richard Haselgrove
One follow-up question. I notice that E@H is displaying the notation (0.5cpu and 0.25ati Etc.) after the gpu units. I know how to adjust the GPU Wu's but can't find where to change the CPU fraction to increase it since E@H no longer uses app_info.xml files.

Can someone point me in the right direction?

Projects never use app_info.xml files - they exist for users with non-standard applications or platforms to create if they wish. I wouldn't recommend it, though, unless you have a pressing need.

You can change the declared CPU usage if you wish with an app_config.xml file (see Application configuration), but I'm not sure that's what you really want. It only affects how many CPU tasks are scheduled to run alongside your AMD/ATI task - it doesn't directly affect the running of the AMD/ATI task itself.

In your previous post, you mentioned "going back and forth between normal processing and "suspended CPU busy'". That suggests that you have your global computing preferences set too low: visit Computing preferences, and verify

Suspend work if CPU usage is above
0 means no restriction
Enforced by version 6.10.30+

(or if you are one of the people who prefers over-riding the web preferences via local settings set by BOINC Manager, check the local version of the 'processor usage' figure instead)
