NumberFields: GPU versus CPU
I just released the new app version for Linux Nvidia Cuda. I tested it on 100 WUs and it averaged about 33% faster over the previous Cuda version. I am now making these same improvements to the openCL versions. If all goes well, I should have new apps for Windows and AMD cards within a week. ( sour...

Re: Running Linux VM under Windows, performance hit?
For performance comparisons, the fact that NumberFields is using fixed credits currently is nice. But the run time variations are huge. On a high-core-count CPU, half a day of testing time is certainly appropriate, but more than that may be necessary on low-core-count CPUs. For quicker testing with ...

Re: Low power video card
BTW, idle power consumption of Turing and Ampere is higher again than Pascal — as far as I have read. Also, I concede that 1070/1080/1080Ti are a little off-topic here, as you specifically looked for GPUs which don't give you the idea to run BOINC on them. My methodology for DC used to be having low...

Re: Low power video card
1080Ti is generally at circa 8 W when idle (in Linux, measured by the board sensor). Or maybe more like 9 or 10 W for a GPU which displays an idle Cinnamon desktop, and 7 W for an unused secondary GPU.
If I remember correctly, 1070 and 1080 had the same idle consumption.

Re: Running Linux VM under Windows, performance hit?
How well are Windows + VirtualBox balancing the load on a 64-thread SMT machine? If you have the time, try a similar test while SMT is disabled in the BIOS. It is safe to say that virtualization comes with a mininum of performance hit when set up accordingly. The business of cloud providers depends ...

Maybe the BIOS version does not bring up the QPI links correctly.
Or maybe one of the CPUs has a damaged QPI link.
