Hello, I've been reading the source of the sqrt program, in the file montgomery_sqrt.c. However, I got stuck at a small description at line 1003-1007 which...
Hi, I'm returning to using GGNFS after some time. Checked out SVN version 311, compiled OK and am running tst250.n. I notice that after the first sieving round...

A leak in pol51opt is in pol5/roots.c: line 184. The easiest fix is to add a single line free(assess_optima); in the last line of murphy_en(), after "*me=e;"...
I've been running a GGNFS factorization on a C133 for about two weeks on PPC. It seems to me that it is stuck in a look of some sort. It sieves, then after...
msieve's guess of the number of relations it still needs isn't good. Are the total number of unique relations increasing on each run? How many unique...
... 2 cents worth: Change rlim and alim to, say, 7000000 or even 8000000 in the poly file and let it dump and reload. You will find an immediate jump of...

Is there anybody currently working on any changes to ggnfs? It would be nice if ggnfs would set the priority of its processes to something less than "normal"....
