Prime95 - Stabilitätstests für CPU und Arbeitsspeicher

Das weit verbreitete Tool Prime95 wird gerne zu Stabilitätstests für übertaktete Systeme herangezogen. Das Testprogramm fühlt insbesondere der CPU und dem verbauten Arbeitsspeicher auf den Zahn. Dabei meldet das Programm Fehler, die bei den Berechnungen auftreten, lange bevor sich Instabilitäten durch einen Absturz des Betriebssystems bemerkbar machen oder andere Datensätze beschädigt werden. Prime95 kann daher dazu verwendet werden, die Grenzen beim Systemtuning auszuloten.

Prime95 29.6 build 7 / 3

07.03.2019

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...

Prime95 29.8 build 5

01.07.2019

Changelog:

New features in Version 29.8 of prime95.exe
——————————————-
1) Support added for AVX-512 FFTs.
2) FMA3 FFTs now have slightly higher FFT crossover points. Soft crossovers are
no longer used by default. See undoc.txt.
3) Torture test dialog box options now based on cache sizes. Options for performing
a weaker torture test are available. Torture tests that use all RAM are now more
stressful. In-place vs. not in-place memory accesses now displayed on screen.

Prime95 30.3 build 1

10.08.2020

Changelog:

1) PRP proofs. This allows GIMPS to double-check a PRP test at less than 1% of the cost of a full PRP test! PRP proofs require lots of temporary disk space. See readme.txt for details. PRP proofs require uploading a large proof file. See readme.txt for details. PRP proof verifications require downloading a modest verification file. See readme.txt for details.
2) Proofs automatically uploaded to server in v30.2.
3) First time LL, World-record LL...

Prime95 30.7 build 3

1) Better prime pairing in stage 2 of ECM/P-1/P+1. This usually results in slightly better
stage 2 timings or less memory used. Save file formats changed - upgrading to 30.7 while
ECM/P-1/P+1 work is in stage 2 will result in stage 2 being restarted from scratch.

2) P-1 converted to use P+1 style stage 2. From the users perpective there is no difference.
Internally a modular inverse is required at stage 2 init, but there is one multiplication
saved for every D-block...

Prime95 30.7 build 4

  • Hyperthreaded torture tests not setting affinity properly for small FFTs. Fixed in build 4.
  • Hyperthreaded in-place torture tests crash for small FFTs. Fixed in build 4.
  • Semi-obscure ECM crash. If an ECM curve needed modular inverses in stage 2 and a subsequent curve needed none (more memory available), then a crash occurred. Fixed in build 4

Prime95 30.7 build 5

  • Assume CERTs will complete before all other work types in computing estimated completion dates. Fixed in build 5.
  • A low-memory situation during stage 2 init of ECM could lead to a crash writing a save file. Fixed in build 5.
  • During stage 2 init, checking for a restart due to a reduction in available memory was infrequent. Fixed in build 5 - might reduce chance of an out-of-memory event.

Prime95 30.7 build 8

  • Options/Benchmark tries to run a hyperthreaded benchmark on non-hyperthreaded CPUs. Fixed in build 6.
  • Another possible crash bug in stage 2 init when memory settings change. Fixed in build 6.
  • ECM sometimes generated excessive roundoff error, usually at start up which then forced using a larger FFT size than necessary. Fixed in build 6.
  • On stage 2 restart due to more memory now available, stage 2 % complete was erroneously reported to be 100%. Fixed in build 8.
  • On stage...

Prime95 30.8 build 12 beta

30.8 build 12

30.8 is now feature complete! Let's call it a beta release.

Changes:

1) Fixed nordi's stage 2 init bug (D > 510510).
2) Changed the way "FFT switching" occurs at stage 2 init. You'll no longer get these messages unless "PolyVerbose=1" is set. There is a small chance this version will switch to a smaller FFT size resulting in a negligible speed increase.
3) This version should not over-allocate memory. For small exponents, say below 50000, the previous version could...
