I thought PPS Sieve had high GPU usage so I didn't bother checking it on my 1080Ti but it was very low even with CPU crunching stopped. 7:49 with 1 task. 9:06 with 3 tasks.

Even on the 1070 and 1070Ti they were around 10:40 and 9:18 at 2x. When at 3x they were running at 16:00 and 13:00. Improvements there too.

On my 2080ti, just 1 PPS sieve task keeps utilization at 85%
I have been running the manual sieving application at the same time; I think it ends up adding 500k ppd, which is about a 20% increase

Looks like I get roughly the same PPD from running 2xPPS sieve at a time.

This weekend's sprint is this Amicable.

05/23/2019 22:00 (UTC) - 05/26/2019 21:59 (UTC)
Amicable Numbers

They have GPU apps but they are extremely CPU bound and every card requires many tasks to fully utilize the card if thats possible for higher core count systems. Many as in 7+ I've heard. Maybe more now. It basically a CPU project now. As the numbers get bigger it becomes less useful on the GPU.

CPU tasks appear to be mt at least up to 32t. Keeps the 1950x pegged with a quick dip every 20seconds or so. I can only get 64 tasks on 32t machine. Yikes 13gb memory and climbing. That might be its max as its going up and down between 10-13.4gb.

I'll load it up and see if it goes up to 48 threads.

About 12:15 to 12:20 per task on my 1950x.
15.1GB of Virtual mem
13.6GB of memory according to BOINCTasks.

Some of the top computers are using CPU only. The top one using 2x RTX 2070s but some others after it are all or mostly CPUs.

Edit: Oh my... trying it on my NV GPUs in Linux. 2-5% GPU utilization. Clock speeds are way down like at stock non-boost and temps are in the upper 30s when they are usually like upper 60s-70s.

I'll be sticking with CPUs for a weekend run of Amicable. 2970WX running 42 threads, completes tasks in an average of 593 seconds, which is nearly 1 million ppd.
