Hi all,
The fourth beta is available. It fixes a few more bugs. See the
whatsnew.txt at the end of this email. An upgrade from earlier betas
is not required, but it can't hurt.
You can download it from
ftp://entropia.com/gimps/v20/p95setup.exe
or
ftp://entropia.com/gimps/v20/prime95.zip
or
ftp://entropia.com/gimps/v20/mprime.tgz
or
ftp://entropia.com/gimps/v20/sprime.tgz
Regards,
George
1) Another fairly uncommon ECM bug was fixed. The bug caused "Factor does
not divide N!" errors.
2) A couple of minor bugs in computing the optimal P-1 bounds to use prior
to a Lucas-Lehmer test were fixed. The program now does a better job at
estimating the memory required in P-1 stage 2. Finally, although P-1
stage 2 working set size is unchanged, the program allocates less memory
in stage 2.
3) Prime95 no longer searches for a smaller factor when trial factoring
discovers a factor. The reasons are two-fold. 1) Version 19 had a
bug where stopping and restarting the program bypassed the search for
smaller factors. Thus, my database may already be missing smaller
factors. 2) As we factor larger exponents to a deeper depth it may
no longer be a quick job to determine if there are smaller factors.
Note, that version 20 will still look for smaller factors if you are
looking for factors below 2^60 with the FactorOverride option in
undoc.txt.
4) The undocumented AMPM feature controls how times are formatted in the
Options/CPU dialog box.
