The GPU is used only for part of the -np step (-np1, if you look at the msieve -h), so it's not being used 100% of the time. Not sure about the CPU since I think the other parts of -np1 (-nps and -npr) are multithreaded. Maybe -npr is not.

Also, based on your filename, are you trying to crack an RSA number? Might want to explain what you're doing...
