I didn't realise the STREAM is using vast amounts of automatic memory. I'd assumed that it was using sane amounts of stack, but the stack TLB slots were getting zapped by all the heap-memory activity. Oh well. I guess that effect is still there, but smaller. I agree that few real-world apps are likely to see gains of this order. More benchmarks, please :) ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libhugetlbfs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libhugetlbfs-devel
