I'm going to guess it's more than 2% increase but even 2%will do it.

Not sure which calculation you're referring to, but if it is the "other project", then B1 = (20/14.6) * 1M * sqrt(24GB/10GB) = 2.1M, with P95 selecting optimal B2. Then do as many tests (probably starting with low P-1) to finish off the range.

Rationale: (20/14.6) * 1M is the "nominal" B1 value for a 24GB allocation, and sqrt(24GB/10GB) is the "penalty" for actual allocation of 10GB.

That seems about right to find the remaining factors for this project while also supporting the "next" project.

Still working on these?
I've not noticed much activity here in the last few weeks.

You could probably P1 6.0. Takahashi is only TF'ING

 2022-01-24, 23:43 #1165 lycorn     "GIMFS" Sep 2002 Oeiras, Portugal 29·3 Posts That sounds good. I'll check which ones are already at 73.

Will you still use the bounds for the pow exponents project? Your call.
