I didn't say they were identical. I said they were related. > SMP (shared global memory) in general would fall flat on its face > well before kilocore, not even talking about mega or gigacore. Not only are there kilocore SMP machines already, but the HPC community is well aware of ways to do non-SMP mega-core machines. Of course, these existing examples say you need a lot of memory bandwidth, more than today's sockets come with. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
