| Di seguito sono consultabili le note di rilascio - in gergo "release notes" - relative al file Prime95 29.4 build 8, nel caso in cui gli sviluppatori abbiano reso disponibile tale documentazione in occasione della pubblicazione del software. Tuttavia, se hai bisogno di maggiori informazioni su Prime95 29.4 build 8, o se le note di rilascio non sono (ancora) disponibili, è comunque possibile procedere con la lettura della descrizione del file. |
1) GIMPS has a new sub-project -- finding (probable) prime Mersenne cofactors.
This sub-project has two parts: 1) Running PRP tests, and 2) Finding
additional factors. To support this new sub-project there are three
new work preferences: PRP on Mersenne cofactors, PRP double-checking on
Mersenne cofactors, ECM on Mersenne cofactors.
2) Like LL tests, PRP tests now support shift counts to aid in running double-checks.
Shift counts are only supported for Mersenne numbers and Mersenne cofactors.
3) PRP tests now support a type of low overhead error checking that almost guarantees
correct results even on flaky hardware. We call this Gerbicz error-checking after
it was proposed by Robert Gerbicz at mersenneforum.org. This error-check only
works for base-2 numbers.
4) Because PRP tests are highly reliable, we now offer the option to do PRP tests
instead of Lucas-Lehmer primality tests. There are 3 new work preferences
similar to LL work preferences: first-time PRP tests, world record PRP tests,
PRP tests on 100 million digit numbers, and PRP double-checking.
If you are looking for a 100 million digit prime, PRP testing is recommended
rather than LL testing.
5) For non-base-2 PRP tests, there is a new option to run each iteration twice and
rollback if a mismatch occurs. Useful only on flaky hardware due to the obvious
high overhead.
6) Minor performance tweaks were made to stage 1 of P-1. Save files are incompatible
in stage 1. Wait for your P-1 test to reach stage 2 before upgrading.
