Are you telling here that you are running 2 programs at 2 cpu's, so junior at 2 processors and crafty at 2 processors sometimes have a big problem that another program is eating up cpu time, thereby locking the whole process? Or did you use the right method involving 2 computers: - dual PII400 - single cpu computer How did you do the test? If you run a parallel program at 2 cpu's against another program at the same cpu's, then the dual version of that program is having major problems, as it cannot search on as a processor sometimes gets blocked by another process. Thereby reducing the nodes a second and plydepths a program running parallel gets. >Fritz 6.66 played enterprising and, at times, daring chess.
