The problem with nicing is that most unix schedulers don't seem to know what nice means,.. you still get a noticable slow down on interactive jobs on SGI boxes even if you've got it npri -h 150, and even though the bruterc4 (and the bruteSSL too) have tiny resident core sizes).

Nice -19 works great on SunOS, it sits there happily eating up just about all the unused CPU time and doesn't interfere at all with interactive use. I guess it's the SYSV (ack) machines that have problems, 'cause the scheduler's too sophisticated. Mark
