My experience is that there are DEFINITE bottlnecks with a variety of Quad core processors that manifest themselves as increased iteration times as you run more instances. On a quad, I have iteration times get progressively worse. Basically, the 4th instance slows the other 3 down enough that I stopped running it - got better overall throughput with 3 instances. On a Dell double Quad Xeon system (one of their workstations), that "breakeven" point is reached at 5 instances, so that is how many I am running.
OTOH, 5 is amazing on a single machine. I would like to hear about the experience of others with this issue. -steve grupp >>> [EMAIL PROTECTED] 09/14/08 3:00 PM >>> Send Prime mailing list submissions to prime@hogranch.com To subscribe or unsubscribe via the World Wide Web, visit http://hogranch.com/mailman/listinfo/prime or, via email, send a message with subject or body 'help' to [EMAIL PROTECTED] You can reach the person managing the list at [EMAIL PROTECTED] When replying, please edit your Subject line so it is more specific than "Re: Contents of Prime digest..." _______________________________________________ Prime mailing list Prime@hogranch.com http://hogranch.com/mailman/listinfo/prime
