YAFU 1.34 freeware

YAFU 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.

YAFU freeware - The Latest Versions History
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
