What is the peak RAM requirement of each WU of the new CPU app please? On Windows.


On Linux it is under 10MB per WU (mean of about 8.8MB).

I don't know what it is on Windows, since I cross compile and don't have a Windows computer to run it on. But it should be very similar to the Linux version.

Why do you ask? Are you seeing issues with the Windows app?

Windows 10:
GetDecics_4.00_windows_x86_64 -> ~4,1 MB
GetDecics_3.05_windows_x86_64_opencl_nvidia -> climbs up to over 300-400 MB on my card.

Maybe this site could help you:

I assume that the tasks with the high ram requirements were GPU tasks. Their ram usage rises constantly

Thank you both.

When I say "asking for a friend", it is accurate in this case as I am looking after some systems in Australia remotely.

All I can tell from here is that a full thread-count of CPU apps causes frequent crashes of either the boinc-client or the whole system. I can see it is not caused by RAM-usage then as they run Gerasim / odlk1 etc on all threads without problems.

Could it maybe be heat? Would you say the new app runs any hotter than the old numberfields cpu app. I am seeing problems on at least 6 different machines which have been stable for many weeks before we switched to NF. It is mid-summer in Australia so I imagine ambient is 30degs C or more

I have noticed a small increase in temperatures with the new app and this is probably a side effect of the improved code efficiency (uses more on-chip cache instead of RAM).

Does Windows have a temperature monitoring app? That might be the best way to determine if there is a heat problem.

Ambient of 30 deg C? That sounds hot to me. This could definitely be a heat problem.

I am using the HWMonitor. Maybe you can use it. Its free to download from the net.
