Win7-64 machine + 8800GTX + vanilla BOINC 6.10.18.: What now?

(1/6) > >>

PatrickV2:
Hi there,

I recently installed Win7-64bits on a Q6600/8800GTX machine of mine, and installed BOINC 6.10.18. GPU was recognized, and apparantly specific WU's are downloaded for cuda. So I'm still running the stock executables, and I like the way it behaves.

I also downloaded from Lunatics, the installer: "Lunatics_Win64v0.2_(SSE3+)_AP505r168_AKv8bx64_CudaV12.exe", but am not sure what happens after I install it.

I know from experience the CPU-executables will increase crunching throughput, but looking through the forums, and looking at terms like 'VLAR-Kill', 'rebranding', etc, I'm wondering what happens with the GPU-part of my crunching activities? Will the new GPU/CUDA executables still only crunch the 'cuda'-marked WU's, or will something change? Will the 'Use GPU only when machine is idle'-option also still work after installing the updated executables?

Best regards amd thanks in advance for any answers,

Patrick.

with 8800 and win7 my experience is that you don't have enought GPU memory and you need to disable some AERO features.

No problems here, Aero was working fine when I had the GPU crunching always enabled. Problems were games, which were running very slowly with the cuda app active. As could be expected. Which is why I set the option to only enable GPU crunching when my computer is idle. Works quite nicely.

Anyway, we're about 1.5 days along, and about 65 views along... If the verdict is that nothing will change (except the crunch-times will go down even further) afer installing the Lunatics pack, I'm all for it. But I'm not 100% sure, so that's why I ask here....

TIA, Regards,

Patrick.

Well, still no authoritative response here, so I made a backup of my BOINC & BOINC_Data directories and installed the Lunatics pack, installing the SSSE3 and the CUDA apps.

After restarting BOINC, all existing cuda WUs were deleted and since I had no CPU tasks, that list was empty too. And, because the servers are apparently down, I could not get any new work.

So I restored my backup, and am now back to the original situation.

The question still stands: how do I install the optimized apps while still retaining the original behaviour? Why did BOINC delete the cuda-specific WUs it had already downloaded?

Will I get the wanted behaviour if I only install the SSSE3_x64 apps, and leave the cuda app in the original state?

Anyone?

Update: Nope, only installing the SSSE3 CPU apps also results in ALL cuda WUs being deleted and all CPU WUs also being deleted because their state file is incorrect.

So, what do I do? Empty the current cache, and only then install the new apps? And, again, how will that setup behave itself?

Regards, Patrick.

What exactly did Boinc say when it deleted your tasks?
