Does that mean you are running 3 tasks 4 threads MT on one CPU? What CPU and how much cache?
What RAM and at what speed? Ripjaws V Series 3200 (PC4 25600) F4-3200C14Q-64GVK
What's old school? Looks like it is still using FMA3, no? YES
I thought I read that it is best to try to keep the tasks in cache memory and try not to use system mem.
You're getting more throughput that way?
Yes
Ripjaws V Series 3200 (PC4 25600) F4-3200C14Q-64GVK
Intel® Core™ i9-7940X X-series Processor# of AVX-512 FMA Units 2 and 19.25M Cache
See
https://www.primegrid.com/forum_thread.php?id=8601&nowrap=true#129682UPDATE May 22nd: It has come to my attention that while CPUs with 2 AVX-512 execution units gain a substantial boost in performance, mid-range CPUs with only 1 AVX-512 execution unit may see a significant
decrease in performance with the new LLR app. Obviously, this is not intended. For the time being there is no workaround for this. If you have a CPU that supports AVX-512, but has only a single AVX-512 execution unit, you may want to use the anonymous platform mechanism (app_info.xml) to run the older version of LLR. With a challenge starting tomorrow, we won't make changes to the app until at least a week. We apologize for any inconvenience this may cause.
