That should have read well under 30 minutes. Also, unfortunately Jason P didn't take my Athlon improvements lying down. He's released a new version of msieve which again beats my sieve comprehensively on the Athlon. Work continues... At any rate, we are still miles ahead of LiDIA, MAGMA and Pari, etc. I also forgot to mention, the tuning parameters for the Athlon are currently commented out in QS.cpp. The tuning that is currently activated is for sage.math, i.e. 2.2GHz Opteron. Sorry about that. It appears I never got around to updating the makefile to take the architecture into account. Actually, if there is anyone who knows a lot about makefiles, I could really use a hand with this. C I know. makefile language I do not.
