We will probably send out the first few tasks (for testing) on Monday.

If you don't want to receive any, opt-out of the "Gamma-ray pulsar search #1" in your Einstein@home project preferences.

What will it require in terms of the GPU (VRAM amount, single- or double-precision compute capability?).

Thanks,
Steve

There is no GPU version of that search yet, I hope that there will be one later.

The first set of tasks will require ~270MB of RAM, they should run 2-5h.

i don't seem to be able to opt out on S6Bucket, but i want to do so.

What can I say but WOW! A truly exciting and scientifically valuable addition to the E@H project's task spectrum, yet another viewpoint upon these fascinating pulsar beasts. I look forward to earnestly crunching such units. :-)

Cheers, Mike.

Heh, when I saw this thread for the first time, the thread that explains what it does wasn't there yet, so I assumed it was for Fermi style Nvidia GPUs. ;-)

Glad it isn't.

Same here. LOL! Dear Enrico is being honoured in many ways. :-)

Please fix project preferences to allow opt-out of S6Bucket tasks. This is set to default. Why?

yup - did not help..

i never ran S6Bucket.

only BRP3CUDA.

no app_info involved.

and i can not opt out on S6Bucket on preferences because it's greyed out and not changeable.

so even if i wanted to, i can not run Fermi LAT only on CPU's if i wanted to..

I'll control remotely my computers from here (Hannover, Germany) when they will receive new tasks. Guess, we'll receive a lot of details about this tomorrow, at the meeting here at AEI.

This thread is for questions, comments and problems related to the new Fermi LAT gamma-ray pulsar search.

I'm running BRP3 currently and would like to try gamma-ray pulsar search. The problem is - I'm using 560 TI card with 2048M so it is running 6 tasks simultaneously because I'm using app_info.xml file to run 6 tasks. Can anybody provide me information what should I add to app_info.xml file to be able to run this CPU task ?

Hi,

Just editing the app_info file is not eniugh, you'll also need the executables themselves, because using the app_info file disables the automatic downloading of new executables.

I think it I s best to wait until Monday when the first work units will be distributed. After that happens, we can extract the necessary information to update app_info files.

If you're using an app_info.xml, I'd recommend to wait some time (a few weeks) with running the new search. While testing we'll update the App a number of times as we fix problems and may add new features. It will be a pain to keep the App updated manually on the Client side.

it would be much easyer for all of us, if you'd provide the option to specificly select that project only in preferences..

I don't understand this.

If you're asking for a simple way to run only the Fermi-LAT gamma-ray pulsar search (which is an application of the Einstein@home project), I'd say that this is not advisable at all.

We won't send out more than a few thousand tasks of that application this week, and an unknown number of these will produce only client- and validation errors. That's what testing is for.

If you would restrict yourself to just that application, you will likely get no work from the project at all.

Hi Bernd, et al.

I guess the feature requested is setting the number of parallel CUDA tasks. This would eliminate the need to use app_info.xml entirely.

* I don't think so. How would this be related to the threads subject, the gamma-ray search?

* If this was still the case, I'd have no idea how to implement this feature. Is there any other project that provides that option and could provide an example (code)?

Sorry Bernd, posted w/o thinking.

Unfortunately I am not familiar with BOINC API. This was just a wish and should go to the appropriate message board.
