Try this: https://www.dropbox.com/s/xo7psmmjfk...SX.tar.gz?dl=0

It is version 30.3 command line version which supports PRP proofs. As always, only for Intel CPUs.

 2021-12-18, 17:20 #167 emiller   Apr 2017 A16 Posts Thanks for the link but this version is giving me the following: Code: dyld: Symbol not found: _curl_mime_init Referenced from: /Users/emiller/prime95/p95v303b6.MacOSX/./mprime Expected in: /usr/lib/libcurl.4.dylib Abort trap: 6 I found a link to this build earlier, thought I'd ask if there was a more recent build.

I just built 30.7 build 9. It likely has the same libcurl problem. If so, let me know and I'll see if static linking is possible.

Available here, if that wasn't immediately apparent:

I think I figured out how to do this, please report on whether it worked.

 2022-01-10, 10:02 #172 congsz   "Cong Shengzhuo" Sep 2021 Nanjing, China 24 Posts A small advice to the Prime95 software In the Prime95 software, when I clicked on 'Advanced--ECM', the default setting of the 'number to factor' is 2^1061-1. However, this number has been completely factored roughly ten years ago, so I wish the default could be changed to 2^1277-1, which is currently the smallest Mersenne composite that we haven't found any factors of.

Yes, but millions of GHZ-days have already been spent on that exponent with no factor found. the smallest factor might be at least 2^300.
Maybe no default number?
(Happy to see another Chinese user )
(ps: why don't you suggest 2^1949001-1 ....)

 2022-01-16, 09:24 #175 S485122     "Jacob" Sep 2006 Brussels, Belgium 182410 Posts With an AVX512F capable processor I see 2 to 4 % lower iteration times on bigger exponents using a 3200 K FFT than lower exponents using a 3136 K FFT. I could force the FFT length. As far as I know, the benchmarks do not test different FFT length for a given exponent.

Will be fixed in next 30.8 build. Only affects TF using the AVX-512 instruction set. It is an assembler bug with an easy workaround.
