Yes, I'm using the software from mersenne.org. Not primarily in the hope of winning the lottery... it just seemed a shame to have all this computing power and not use it to it's fullest. (I tried for years to find a LGM with SETI, but that was a bust). In any case I am curious about how these two processors are used, and if they are used at all unless I do something specific about them. I've discovered that they can indeed be coaxed into operation, and wondered if I could do this with Fractint. It would seem to be ideal for long deep zooms. Richard has suggested "a small command line utility to view, kill, suspend or set the priority and affinity of processes, perhaps from a batch file" I'll have to get that and see if I can manipulate the affinities of the processors and Fractint. Why do you ask, by the way? Expecting a tip if I win? :-) John W. Oh, by the way, there's a chance that I may abandon this line of enquiry. My machine has one of those variable speed fans. It's either stopped or very quiet when the machine is idle, and revs up when work is being done. Since I put another prime search on the second processor that fan went up to high revs and stayed there! ----- Original Message ----- From: "Paul N.

I followed instructions to start up a second Mersenne Prime Search on the second processor, and all seems well... both of them are hacking away.
Are you trying for the $100,000 award to the first person (or group) to discover a ten million digit prime number?? :-)
Are you using the software from: http://www.mersenne.org/
