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 ...
