Hello... I just did some tests trying to malloc() memory on an opteron and a xeon system... I wonder why I see regression for the opteron in 32bit mode. Comments welcome (workarounds even more). Anyhow my observations: malloc large block: opteron -> up to 7G (64bit exe) -> up to 1500M (32bit exe) xeon -> up to 2000M malloc a couple of blocks of size 100M: whole process (100 M steps) opteron -> 7700M (64bit exe) -> up to 2200 (32bit exe) xeon -> 2700M So one 'looses' 500M.
