windows default iconYAFU Publisher's description

An interactive command line utility for integer factorization.

An interactive command line utility for integer factorization. Implements multi-threaded SIQS as well as ECM, P+1, P-1, SQUFOF, Pollard's Rho, and Fermat's method. Also contains a very fast implementation of the Sieve of Eratosthenes.

What's New in This Release:

В· no longer print SKEW line to nfs.fb files
В· add issquare and ispow to function list
В· cleanup of siqs tdiv code: now requires SSE2
В· added perfect power checks to siqs and nfs
В· on NFS restart, check any rels found against min_rels instead of always proceeding to filtering
В· support for large nfs jobs on windows (file size limitations removed)
В· fix for the "skipping blank line" infinite loop sometimes encountered during -batchfile runs
В· fixed estimation when allocating memory in SoE wrapper - now gives better estimates and saves memory
В· fixed bug introduced in 1.28.4 where rho() doesn't detect PRP factors correctly
В· if gnfs-lasieve binaries are not detected prior to starting an nfs job that requires sieving, siqs is started instead of aborting (and a warning message is printed to the screen and logfile)
В· added a check for a valid siqs savefile and restart siqs inside of factor()
