People on the list just discussed this - not too meaningfully - but... I don't know if there is a coded in limit in either 6.xx or 7.xx. People were more talking about a practical limit, meaning how many could be efficiently handled. For 6.xx they seemed to think that something between 4 and 8 were practical limits. But, this is assuming all CPUs were being used on the same task. Having multiple tasks might increase this. Again, I don't know if somewwhere there is a coded in or configurable limit to how many CPUs it will talk to. Someone who knows the code should answer that. No one has attempted to respond in terms of V 7.xxx as far as I have noticed. ////jerry > > THANKS IN ADVANCE > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
