I didn't get many responses to my request for benchmarks (in the primenumbers group), so I'll try here. I would like to build a spreadsheet that compares the...
Well done to Daniel Heuer for: 9999 10^95019-1*10^47509-1 95020 p16 03 Near-repdigit Palindrome Surely the NRD top will be raised this year and most likely it...
... Thank you, I hope to break the 100,000 digits for palindrome (maybe near-repdigit) during this year. For chris, it seems better to use this form in the...

... It will be. I am running these primes through some of the machinery for the new lst, and part of it is a "canonicalizer" which rewrites primes when...
Hello, Can anybody help me on the following: Factoring the key N would result in 2 and only 2 prime numbers (pq), one of these numbers will be less than or...

... I think you need to estimate how long you might spend doing 10^300 divisions....
Thanks for that update, Chris. Handling nearly 60k titanic primes cannot be easy. I just noticed that a third of these are from a single person: Patrick...
I have collected 12 benchmarks for PFGW for various hardware combinations. You can see from the benchmarks how much of an advantage it is to have a P4. The...
Jeroen your number N is approx 2*10^617 sqrt(N) is approx 4.5*10^308 Number of primes < sqrt(N) is approx 6*10^305 1) generating all these primes, even...
... Mark, Something outcomes of the test for P4 very doubtfully look! For example see n=32768: P4 2266 MHz - 6 P4 2595 MHz - 4.9 P4 1800 MHz - 29 -???? ...
... Mark, thank for corrections. It is the really useful information. But she would be even more complete, if it was specified in what mode was tested P4. I...

... They are indeed big. I am working on 1027 digit numbers though and was getting that message. I am going away for a couple of weeks and wanted my machines...
NOTE NOTE NOTE, The message "Possibly a number too big for alloca version of GMP" is a very bogus thing. ANY exception that is "caught" at a certain location...
... That is dependent upon the verion of PFGW. For example, AFAIK PFGW version 1.1 does not support SSE2, thus the P4 would not provide much more of an...
"Estimate for PRP Test (> 30000) (in seconds unless otherwise noted)" Could this be more specific? Are the timings for an optimised form such as k*2^n+1 (k...
Ok, first off, benchmarks in PFGW are probably not the most bug free code but they should get you results that are "in the ball park", and they "should" allow...
I am using the output from NewPgen for CC of length >5 and for these output files PFGW only tests the CC upto length 5. Is this problem known?!? Gary ...
