Re: GPU Support: Post Your Problems/Questions Here

At least you remember, still, that you wrote it down, you thought :D

(enough of the scherzo ... back on the regular program of GPU problems/questions.)


This is the most scherzando posting in a while....

Re: GPU Support: Post Your Problems/Questions Here

You are on client 6.10.58 or earlier? Client 7.0.47 does a good job and keeping the run time estimates at normal.

I upgraded from 7.0.28 to .47 and GPU WU estimates are still wrong.

Re: GPU Support: Post Your Problems/Questions Here

Maybe patch Tuesday flunked your display drivers [Mine took 295Mb on the W7-64 system]. Can't imagine why the client would suddenly give up, and 6.10.xx definitely less detection capable. Of course, you've done a boot and considered posting the top 35 lines of the startup log to inform us how your client is configured.

Re: GPU Support: Post Your Problems/Questions Here

I would suggest getting an i7 instead of the AMD FX processor to pair with your HD 7950. The power consumption of the FX series just doesn't justify choosing it instead of an i7. Why not an i7-3930K or an i5-3570K?

Try reading page 40 of Custom PC UK Issue 112 (January 2013) and page 8 of the same issue:

"The result is that AMD's new FX CPU isn't worth considering. It still uses and unhealthy amount of power, and its performance is comparably terrible in almost everything except heavily multi-threaded software."

"Despite improvements, AMD's FX-8350 remains painfully outmatched by the Intel Core i5-3570K...the FX-8350 is a thoroughly uncompetitive and unattractive CPU."

How much time do you think it should need?

Re: GPU Support: Post Your Problems/Questions Here

It is strange - for me it is re-calculating it few times a day confused

Re: GPU Support: Post Your Problems/Questions Here

Old clients recalculated DCF and TTC every task that is completed, aggressively up when longer, slowly down when faster. Since <dont_use_dcf/> is put in place [a WCG server instruction only working for the WCG project tasks], clients understanding that instruction just follow the mean flops that's transmitted in task headers of new work assignments. This projecting is at the app level, so theoretically the CPU tasks would not be affected by the GPU Tasks actual runtimes, but since the tasks come from the same pool, the FLOPS used to project the time is likely equal.

Of course, if the client benchmark has not run [I've disabled it with <skip_cpu_benchmark>], then fast or slow CPU speeds, the projections are pretty constant, at least, on my CEP2/HCC1 mix octo, the HCC just loiters between 3:37 and 3:41. The long nor the shorts affect the TTC of still to start jobs, fractions of a minute for CPU tasks, whenever new work arrives [never sat there and watched it happen, so it's big thumb theory].

Re: GPU Support: Post Your Problems/Questions Here

I have no problem with CPU WU estimates, only the GPU ones are wrong. The HCC estimates you're talking about are for GPU workunits? Mine are still exactly 1:36, but like I said, actually take about 9 or 10 minutes. Now all of them are estimated wrong, originally it was just some, so it's getting worse, not better.

And btw.:
"its performance is comparably terrible in almost everything except heavily multi-threaded software."

What is BOINC if not a heavily multithreaded workload?
