Links to Precompiled GMP-ECM versions

wblipp · 2005-05-09, 23:25

This thread is for links to versions of GMP-ECM that have been compiled for various systems and discussions about their relative preformance. Please include information about target processors and operating systems and environments (i.e. Cygwin or MinGW or ?) and about the code and patch versions used.

Hi !

I have access to a Celeron M 360 (1.4Ghz, 1Mb fast L2 cache) and, whereas ggnfs is only 15 % slower with the celeron than with a 2Ghz OC Duron, P4 gmp-ecm pre-compiled binaries are 45-50% slower...
I know that Pentium M and Celeron M are P4 compatibles and I wonder if this difference is inherent to the program or if a pentium M gmp-ecm built would speed ecm a lot?? (ggnfs is Pentium M optimized)
BTW, can someone provide me pre-compiled pentium M win32 binaries or a link to such binaries (or simply an answer, to see if it's worth the time to install linux on the portable, just for compiling gmp and ecm myself with P.M optimizations...).

Thanks.
Regards.

Philippe.

Hi Philippe

You don't have to install Linux to compile an optimized ecm. If you're running Windoze you can try to follow my guide to compile it.

Good luck!

Here are PentiumM-optimized binaries.

Hi OmbooHankvald!
I have formerly tried to compile gmp-ecm with cygwin (and I must say that compiling gmp with cygwin isn't so easy) and binaries were slightly less efficient than those compiled by others with more experience with gcc flags...That's why I was asking for binaries.
I do indeed appreciate your guides and have visited the page you show me a few days ago... Lacking a fast internet connexion, it is easier for me to download a binary than the whole mingw suite...
Thanks for helping me !

Hi Mystwalker!
Thanks a lot for the binaries!...I'll try them in a few minutes and, if interesting, post my results !

Best regards.
Philippe.

Anyone interested in compiling, for me, the GMP-ECM 6.0.1 for an AMD 64 windows machine?

Thanks in advance,

Carlos

em99010pepe · 2006-02-02, 22:43

Anyone?!?!?!

Carlos

wblipp · 2006-06-18, 20:17

Bump.

Are there 6.1 executables available for various configurations?

I've determined the 6.0.1 Windows executable I'm using on P4s and Athlon XPs fails when doing ECM with B1=260M, giving the message

GNU MP: Cannot allocate memory (size=562053120)
