BTW: if some users had observed before this weird behavior when a task's status would be shown as not currently running but still showing ongoing progress, please let us know if you still see this. The new version that Oliver made available now is hopefully fixing this.

Ive seen it with the new version...
Im using Boinc 6.10.60 and Ive changed the number of "reserved" cores which triggered the benchmarks, and while the status displayed for all the tasks was Suspended (due to the benchmarks running), the progress bar was still going on... (on an i7-3770 host with a gtx690, Win7 pro 32b and 301.42 driver)

EDIT: I was not crunching for Einstein in this host before, but Ive not seen that issue in my main Einstein host: i7-860, 2x560Ti, Win Vista ultimate 32b, and 301.42 driver)

No, definitely not

No, definitely not slower,

Thanks, got it.

The API information still looks odd:

Quote:

einsteinbinary_BRP4
131
7.1.0
API_VERSION:T(0,12613)=s8MajorVersion:(0,87),0,16;MinorVersion:(0,87),16,16;Revision:(0,87),32,16;Reserved:(0,87),48,16;;
API_VERSION:t(0,12613)
API_VERSION:t(0,12614)=(0,12613)
LPAPI_VERSION:t(0,12615)=(0,12616)=*(0,12613)
...

That's an unrelated problem due to sloppy code in BOINC's update_version script which has affected all Windows binaries as of v1.28. We identified the problem, fixed it and will deploy new v1.32 binaries. The binaries will be identical to v1.31 but our server will serve them with the corrected api_version content. We'll also patch the problem upstream.

Well spotted!

Oliver

I'm seeing that the Windows

I'm seeing that the Windows 1.31 AMD_OpenCL app takes up quite a lot more CPU cycles than the 1.28 equivalent did. BOINC is set to use 3 CPU cores, leaving the 4th to run my GPU + whatever else there is.

Well, the whatever else there is slows down since v1.31, like the Linux VM I run in VirtualBox. It halts for minutes at a time, and when I then check Windows Task Manager, the Einstein GPU process is taking up 25% of the core (thus running at 100%). It does this quite regularly.

At all other times it takes a minimum of 4 - 7%, higher than the v1.28 app took. That one peaked at 3%. Run time and CPU time hasn't really increased much, it's the same-ish between applications.

Hi there.... I'm not

Hi there....

I'm not getting GPU tasks because Einstein thinks my card does not support OpenCL...

Setup:
Windows 7 x64
GPU: HD 7950 with 12.10 CCC
Boinc: 7.0.25

Boinc log file :
18.11.2012 18:28:38 | | ATI GPU 0: AMD Radeon HD 79x0 series (Tahiti) (CAL version 1.4.1741, 3072MB, 3032MB available, 8512 GFLOPS peak)

Einstein Server log:
http://einstein.phys.uwm.edu//host_sched_logs/6069/6069022

I'm running other projects on the card in OpenCL ....

Thanks for the help
happy crunching

All 3 versions look pretty

All 3 versions look pretty much the same on this GTX 550Ti

Try updating your BOINC to 7.0.36. It's what fixed it for others.

When Einstein says the GPU does not support OpenCL, BOINC won't have detected it either. If your BOINC start-up messages do not show a line that says something like "OpenCL: ATI GPU 0: AMD Radeon HD 79x0 series (driver version CAL 1.4.1741, device version OpenCL 1.2 AMD-APP (923.1), 3072MB, 3032MB available)", then BOINC did not detect OpenCL capability on your GPU, and thus Einstein and other projects relying on BOINC detecting the OpenCL capability, can not use it.

OK now it works, I can see

OK now it works, I can see the CL line now....
Let's see if E@H will send tasks .... and YES the first GPU task is about to arrive...

Thanks for the help

Your BOINC client is (was) too old, we require at least 7.0.27 for OpenCL tasks.
