now i'm wondering, using the same parallel algorithm which one would perform better? a 1 cpu quadcore machine or 4 cpu single core machine?
most of my j system running on the server are still on a 4 cpu intel xeons. most of the new deployments are using the multi-core units. i am under the impression that the single core multi cpu (4 cpu X single core) setup is faster than the multi-core multi-cpu (2 cpu X quad core) but I have no metrics to back this up. just an impression. am i right or just batty as usual? r/alex Sent from my iPhone On Feb 15, 2010, at 5:03 AM, "Don Guinn" <[email protected]> wrote: > Probably not necessary to be really accurate in splitting up the > work.
