Hello Anton I haven't tried the one you reference above but I have had trouble with earlier attempts to add inttypes.h to Visual Studio. In fact this might Fri, 06 Nov 2009 14:58:14 GMT Anton Korobeynikov http://tech.groups.yahoo.com/group/ggnfs/message/2467 http://tech.groups.yahoo.com/group/ggnfs/message/2467 Hello, Brian ... At least we need to use proper format specifiers, since "unsigned long" is still 32 bits on win64. I was told that stuff from Fri, 06 Nov 2009 14:30:55 GMT br_gladman http://tech.groups.yahoo.com/group/ggnfs/message/2466 http://tech.groups.yahoo.com/group/ggnfs/message/2466 ... That wouldn't work for the Windows build because the Microsoft compiler doesn't support most of the C99 stuff and has no stdint.h header file. We could Fri, 06 Nov 2009 12:40:31 GMT Anton Korobeynikov http://tech.groups.yahoo.com/group/ggnfs/message/2465 http://tech.groups.yahoo.com/group/ggnfs/message/2465 Hello, Everyone ... What was the sort of garbage seen? ... wrong. We have: printf("%d %lu %u ",x,qx,ulqx); x here is of type i16_t qx - u64_t ulqx - u32_t The Thu, 05 Nov 2009 20:35:51 GMT Jeff Gilchrist http://tech.groups.yahoo.com/group/ggnfs/message/2464 http://tech.groups.yahoo.com/group/ggnfs/message/2464 ... Great find, this has been updated in the SVN code so it will not longer produce that output. ... That is a very good question. I'm not sure if anyone here Wed, 07 Oct 2009 14:49:27 GMT Jeff Gilchrist http://tech.groups.yahoo.com/group/ggnfs/message/2463 http://tech.groups.yahoo.com/group/ggnfs/message/2463 ... The ggnfs binaries are command line tools so you can double click on them, you need to run them from either a cygwin shell or from a command prompt Wed, 07 Oct 2009 08:56:33 GMT jamal othman http://tech.groups.yahoo.com/group/ggnfs/message/2462 http://tech.groups.yahoo.com/group/ggnfs/message/2462 Hi dear group ,after downlouding ggnfs 340 and extracting and downlouding  CYGWIN and install , on double clicking CYGWIN I  get a flash window only and on Sun, 04 Oct 2009 09:14:08 GMT chris2be8 http://tech.groups.yahoo.com/group/ggnfs/message/2461 http://tech.groups.yahoo.com/group/ggnfs/message/2461 Hello, I've tested the matrix solving step with 1 vs 2 threads on a single core CPU with hyperthreading. It runs *faster* with 1 thread than with 2.

See http://mersenneforum.org/showthread.php?t=12125 for a discussion of factoring a 1536 bit general number.

I have had a number of snfs factorings, which have bombed out immediately with the previous version.

I suppose it's silly to ask, but is there any reason why polynomial selection couldn't be made to use multiple CPUs? John.

Polynomial selection isn't multi-threaded so only one gets used. All 8 will get used for sieving and some parts of the post-processing as well. Jeff.
