1) Message boards : Number crunching : FMA3 vs AVX (Message 3373)
Posted 1 Apr 2017 by scole of TSBT
Do you see all cores clocking at 4.2Ghz when SRBase is running? Some CPUs automatically downclock when running AVX even thought temps are fine. I have a Xeon Broadwell-EP ES system that will clock at 2.8Ghz running non-optimized apps but downclocks to 2.3Ghz when running SRBase or project apps which use AVX/AVX2. And the i7-6700K only supports 2 memory channels. Are you using 2x 8GB or 4x 4GB sticks? And what speed is yours and Rebs?

Reb, what system are you running with 6 memory channels?

If a WU for a particular app typically takes 12 hours using 1 core, then you earn 12 hours on WUProp.

If you now use 12 cores to crunch that 1 WU and lets say it takes 1 hour using 12 cores, then will you earn 12 hours work on WUProp or 1 hour?

Will WUProp record all cpu time on the multi-thread WUs? Most do, some don't.
