It seems like no recent activity on 8.2M and no reservations noted here as well. If so, I want to take this up for my next range.

If anyone has any objection, it would be kind of you to let me...

This doesn't make sense. What were the stage 1 FFT sizes, per iteration timings and worker/thread configuration for these two runs?

This B1-M is very nearly fitting with sqrt(ref RAM/allocated RAM) * B1@ref RAM !!! Also, eventhough it says it is lower GHzD, I suspect that the actual runtimes are pretty close or even increasing,...

I suspect that a good rule of thumb for B1 adjustment would be sqrt( ref RAM / allocated RAM) where ref RAM should be a good "high end" RAM allocation like 24GB (out of a typical 32GB installed RAM)....

Ok. These are definitely showing better thruput compared to 8w tests.

There is a chance that you may get slightly higher thruput by optimizing Infinity Fabric speed. By default IF runs at RAM...

Can you also do 4w (16t per w) as well? For wavefront exponents, 8 worker will not fit entirely within L3, but 4 worker will.

Also, what is your RAM speed?

5 digits = factor of 2
1 digit = factor of 2^(1/5) ~= 1.15
3 digits = factor of 2^(3/5) ~= 1.52

Linear interpolation between 1 & 2 wouldn't be too far off though. You'd get 1.6 which is good...

As I mentioned in that other thread, the residues produced are the same. You're assuming PRP-CF does a standard Fermat test; it does NOT.

You can remove the dependency on memory bandwidth if you have sufficiently large L3. 64MB L3 of 5900X can hold current wavefront FFT in its entirety.

There can be three possible shape for B1 as a function of exponent.
