The project will be taken down in about an hour to perform an update of the BOINC server code. Ideally you shouldn't notice anything, but usually the world isn't ideal. See you again on the other side.

Does the problem persist?

We are testing the behavior of "CreditNew" on this project and will try to fix it if necessary. Be prepared for the unexpected!

Intel GPUs are now being shown by the project in the computer details pages:

Computer 9008


But 'Use Intel GPU' isn't being shown on the Albert project preferences page in spite of there being intel GPU apps available, perhaps those apps need their settings adjusted?

The machine has been restarted.

Note: Local time UTC+2 (Prag).

If your are going to use Dave's random number generator, I leave the project. Some CPU projects have fixed it to number generator of expected and acceptable range, but no GPU project has been successful in that deal. Good luck.

EDIT: Before leaving I'll try my favorite joke - using app_info to get BPR4 CPU task to be crunched by intel_gpu. I expect credit 0.5 instead of 62.5. Can be seen as wu 590960.

We know all that. The purpose of this test is, very specifically, to test and try out some fixes to CreditNew that some volunteers have spent the last nine months developing.

It would be most helpful if you would remain attached to the project, to generate some baseline data from a good range of hosts.

Albert has been chosen for this task specifically because it's a test project where nothing is expected to work anyway!

hold your horses please!

What we are specifically trying to do is to make something that actually WORKS out of David's RNG!

But for that we need to verify first that we see on Albert what we know from SETI main, before we can go on to stick a proper algorithm into it.

So, PLEASE, bear with us while we establish the system works as expected (i.e. is crap) and then apply the patches into the critical areas.

I'm getting work OK on 'CPU only' requests.

But I've attached some extra hosts, which are requesting NVidia work as part of project initialisation - that's returning 'internal server error' (see email). I'll have to find some way of blocking that initial request - seems to be fine after that's out of the way, using a 'CPU only' venue.

OK, if Albert is not for testing of applications only, but also for the credit system (as SetiBeta and ralph), I have no problem to help to generate baseline. It is important to know it. It that case I have no problem with low and random credit.

only worked after moving the host to a _fresh_ venue that only has CPU ticked.

My i7-2600K got ATI/AMD work, But when I suspend Seti (where it's crunching OpenCL Seti v7 work), nothing happens, the ATI/AMD Wu isn't started.

Edit: Finally I manage to get it to error:

My host 11361 got some CUDA work (like result 1448685), which failed with 'No suitable CUDA device available!' - although there's a fully functional "NVIDIA GeForce GTX 750 Ti (2047MB) driver: 335.28", which crunches CUDA at other projects.

Our plan class specs that were (semi-)automatically converted for the new server code were somewhat broken, causing probably all kinds of oddities for GPU tasks. Should be fixed now.

+1 Still no setting in preferences to select intel GPU, like you can for AMD or nVidia. Other GPU projects have this, even Einstein.

All my AtI/AMD tasks are predicted to take six seconds, when they get to 2 minutes 6 seconds they error:

Holmis reported the same for BRP4G-cuda32-nv301 in the problems area, except he inocculated his against "Exit status 197 EXIT_TIME_LIMIT_EXCEEDED" with a big boost to rsc_fpops_bound.

I guess one of us (and that probably means me) should fire up a GPU fetch and compare the calculations in the server log with what actually ends up in client_state.xml
