[B]M3321928171[/B] to 2[sup]78[/sup] is 15% complete.

This is going to take a long time to finish. Probably sometime in February of 2010.

M3321928171 Unable To Complete
 
My old desktop died sometime during the night. Fortunately, I was running Factor5 from a 2GB flash drive, so the "status" file would be written there in case anything went wrong. It was around 17% complete. Below is the contents of the "status.txt" file.

[B]I would very much like someone to pick this up and finish it.[/B]

Factoring M3321928171 from 2^77 to 2^78 17.571% completed.


edit : Restarted at zero to use 4 cores. I don't think I can use the status txt file to continue with different number of cores. Just a couple days to redo to 17% anyway.

Thank you for taking it on. Much appreciated.

The problem with the HP turned out to be a toasted CPU. I found one side of the heat-sink loose which allowed it to tilt out just enough to lose contact with the CPU. Using plastic locking arms was not a good idea on the part of Intel at the time. The motherboard was not scorched; don't know if it would still work or not.

Regardless, thanks again...
