Right now, your only option is to run from scratch using v2.6c (as long as it's the first exponent in the range file, the run should be OK), or (what may be faster) use 2.7x at 160K, e.g. by explicitly listing the run length in interactive mode - delete or rename the worktodo.ini file and enter s.t. like Mlucas <== perhaps add output redirection on this line... 2608007,163840 <return> <return> You can redirect the output to a file and use crtl-Z and bg to restart the job in background mode, allowing you to log out. I'm working on adding some kind of automated error detection/FFT length resetting to the next release, but it adds a lot of program logic and hence takes time to do - I didn't want to wait for that before releasing a beta version. Thanks for the info - keep those bug/problem reports coming. -Ernst _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
