Just wondering what people think would be the best PrimeGrid subproject/app to run on this V4 Xeon?

(Xeon E5-2696V4 which is the OEM version of the E5-2699V4)

https://ark.intel.com/content/www/us/en/ark/products/91317/intel-xeon-processor-e5-2699-v4-55m-cache-2-20-ghz.html

* 22 cores | 44 threads

* 2.2 GHz - 3.6 GHz Turbo (2.8 GHz all threads)

* 55 MB L3 Cache

* AVX2 (etc)

* 32 GB RAM in Workstation

And given the subproject(s) you mention:

> Should HT be turned off? (if so, is that in the BIOS, or by using 50% of BOINC CPUs?)

> Should an AppConfig file be setup to use MT?

Thanks..

What is the criteria?

Most credit?
Go for 321 Sieve - a lot of cores and lack of AVX-512 doesn't matter.

Some primes?
I would go to PPS.

Fastest results?
Not much - 8-core with AVX-512 and higher clock may do better.
