YAFU 1.34 freeware
... or Yet Another Factoring Utility is an interactive Command Line instrument for integer factorization. Implements multi-threaded SIQS as well as ECM, P+1, P-1, SQUFOF, Pollard's Rho, and Fermat's method. The program also contains a very fast implementation of the Sieve of Eratosthenes. ...

| 1.34 | Feb 27, 2013 | New Release | · new sse2 code: faster small prime sieving in siqs · new sse4.1 code: even faster small prime sieving in siqs · new sse4.1 code: faster large prime bucket sieving in siqs · makefile additions to include sse4.1 code in the fat binary on compatible hardware · runtime flag to utilize sse4.1 code on compatible hardware · enabled multipliers for fermat factorization · fixed bug in qs filtering · fixed a bug in .job file filling - handle no line break on last line · fixed "too many refactorizations" bug · added a function to factor all single precision integers within a specified range · frontend calculator now uses GMP · Updated "gnfs.h" to use GMP · automatic processing of several SNFS forms: N = a*b^n +/- c, for b < 100, c < 2^30, N < 1024 bits N = b^n +/- 1, for b > 100, N < 1024 bits N = a^n +/- b^n, for gcd(a,b) = 1, a,b |
| 1.33 | Oct 29, 2012 | New Release | · made "found poly" messages much less verbose · using /r instead of printing backspaces now in ecm.c and SIQS.c · ggnfs jobs launched by yafu will now print out individual .last_spq files per thread, although they are still not used for anything · get rid of blk_rel_count experiment code in siqs · add the beginnings of CUDA squfof support - although it is far from working and probably not even beneficial at this point. currently protected by HAVE_CUDA definition · more work on tinySIQS, but still not fully operational. · added more fclose's · fixed bugs that caused crashes when inputs numbers approached or exceeded 1024 characters in batchfiles. · updates to text output of factor() to prevent window scrolling · (re)support builds without NFS=1 · got rid of cat.exe warning messages in windows that don't have unxutils · slight cleanup of nfs state machine · improved min_rels calculation · added ability to parse user supplied job files and supply missing parameters |
| 1.32.1 | Aug 2, 2012 | New Release | · added fclose's and fixed gethostname alloc problem · removed the "found time record" messages from poly select · remove the printing of rels during .dat parsing (available with verbose mode -v -v) · changed siqs cutoff back to 115 bits |
