[FLASH-USERS] 64 Bit FLASH on Opterons?

Hi all,

Has anybody out there successfully compiled FLASH in 64 bit for
Opterons? I can get it to run, but only 50% as fast as 32 bit and
using twice the amount of ram for the same size problem - which I
don't consider successful...

I am using the PGI compilers (version 6) on SUSE 64 and MVAPICH
(which I compile in 64 bit as well). The additional compiler flags I
am using are -mcmodel=medium -tp k8-64 -Mlarge_arrays

Thanks!
Sebastian
