Anyone else notice that their Amicable RAC has been dropping? Mine has dropped more than 20% since February 2. I only crunch GPU tasks for Amicable and Amicable is the only project that uses my GPUs.

TIA for any ideas. I apologize if this has already been extensively discussed.

It depends on which number ranges the project is checking. Some are slower, some are faster. Thankfully, part 3 WUs are much more uniform, and I tweaked them to be a bit faster than what part 2 has.

Thanks for the explanation. Glad to hear it is not a problem with my machines.

My RAC has more than doubled in the last 7 days. It certainly appears that recent WUs are being crunched more quickly than the WUs I was crunching last week. I am going to look at my recent results to see if I am on track to hit my all-time high in Amicable throughput, which I achieved between January 26 and February 2.

I'm using CPU only (spare threads on a dual Xeon setup), and since the change to part 3 (around 27/28 March) my RAC has dropped to about a quarter of that previously. No changes on hardware / resource allocation.
Is this normal?

Part 3 WUs are much faster on GPUs compared to CPUs. I might launch the CPU-only application to search for the remaining amicable pairs (m=m1*p where p > 10¹⁴) before the part 3 finishes to give some meaningful work to CPUs. But it's not ready yet because I still need to find a good way to parallelize it.
