OK time to move the battle fleet to this.

Had a minor glitch as I realized too late that my default setting was for the sub-project The Riesel Problem and it should be Sierpinski / Riesel Base 5 LLR. Once the original WUs get processed the output of SR5s should start showing in the stats.
Currently I've improved from 40th to 20th. Our team effort has improved so we are now ranked 13th. I believe top 10 is achievable.
Today I've added 16 Amazon AWS EC2 instances: c5.2xlarge Xeon Platinum 8124 8 core processors at 3.0 GHz with AVX512. They are running multithreaded under Linux. Previous experience showed that the higher core instances didn't scale correctly so the much pricier CPUs were not fully utilized. I hope the 8 cores run at 100% utilization.
My two Intel Coffee Lake 8700K's complete the SR5 tasks in about (EDIT) 54 minutes in multithreaded configuration.
My two AMD Ryzen 2700X's complete SR5 tasks in about (EDIT) 1 hour 7 minutes in multithreaded configuration.
