Well, the current range of Mp candidate values (just under 8,000,000) is described as using a 63 bit 'factor'... I would assume eventually this has to go to 64 bits, but I'm not clear on the relationship between the exponent and the FFT size and the 'fact bits' listed on the test status

Mersenne: Laptop users: Automatically suspend sieve, mprime, etc. when off the grid

I run sieve on a laptop, and I don't want to run the battery down with sieve when it's not plugged in to the wall. So I wrote the following shell scripts, which start it automatically, run it nicely, and suspend it when the battery is low. You will have to have APM in your kernel to get anything
