Hi all, I've uploaded a version that fixes 2 bugs in the new P4 prime95. 1) Trial factoring was broken. In switching to MASM 6.15, an assembler bug caused the factoring code to blow up. 2) I restored a FPU init instruction that I accidentally deleted. This caused the excessive round-off errors when running the old FFT code. Again, *FOR P4 USERS ONLY* the fixed version is at ftp://mersenne.org/gimps/p95v21a.zip Have fun, George _________________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
