Bug 764350 – sci-mathematics/gimps-30.4.8 - version bump

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Paolo Pedroni 2021-01-07 17:03:03 UTC]

Version 30.4 build 5 of sci-mathematics/gimps is available for download.

amd64 only ATM.

Changelog:
1) Faster P-1 stage 2.
2) Faster ECM stage 1 and stage 2.
3) Gwnum library overhauled.  Many functions deprecated.  Replaced by more
powerful gwmul3.  New functions that compute (a+b)*c and (a-b)*c with less
memory accesses.  Faster conversion to and from binary.
4) ECM and P-1 can find the best B2 value for the amount of memory prime95
is allowed to use.  For ECM, this happens when the worktodo.txt line sets
B2=100*B1 which is the default assignment from the PrimeNet server.  For P-1, the
best B2 is chosen when the worktodo.txt line specifies the trial factoring depth.
  For example, "Pminus1=1,2,20000003,-1,500000,0,70" chooses the best B2
bound for B1=500000 given that M20000003 has been trial factored to 2^70.

This is considered beta-quality software by its author, so it will not be considered for stabilization.

Github PR will follow soon.

Version 30.4 build 6 is now out. Nothing new in the changelog, just bug fixes. Will update PR soon.

[Comment 2 Paolo Pedroni 2021-01-14 15:55:32 UTC]

PR updated

[Comment 3 Paolo Pedroni 2021-01-19 10:31:50 UTC]

Version 30.4 build 7 is now out. Nothing new in the changelog, just bug fixes. 

Fixed a memory corruption problem when limited stage 2 memory resulted in selecting N^2 pooling instead of 3-mult pooling.

PR is already up to date.

[Comment 4 Paolo Pedroni 2021-01-25 14:17:58 UTC]

Version 30.4 build 8 is now out.

No bug fixes. There are 2 new modular inverse pooling algorithms. Previously there were two algorithms for pooling N values:
1) 3*N multiplies, N extra temporaries
2) N^2 multiplies, 1 extra temporary
The two new methods:
3) 3.44*N multiplies, N/3 extra temporaries
4) 3.57*N multiplies, N/7 extra temporaries

This gives prime95 more options in picking an ECM stage 2 plan especially in low memory situations. Expect a small speed increase in some situations.
