Afer some reasonable troubles, I managed to compile and run ROMS on my Dell laptop. This was with Linux Red Hat Enterprise Advanced Server 4, the intel compiler 9.1, only one supporting, as of May 2006, the Intel Centrino Duo (dual core) processor.
Most important. The intel fortran compiler for linux, version 9.1, does not mention (man ifort) the Intel Centrino Duo in its list of processor options. Treat the centrino duo (not listed) as a Core Duo (listed). So, use -xP and -axP as compiling flags.
To make this run, and this unrelated to the processors but to ifort, you need to increase your stacksize and also use large tiling numbers.
ROMS ran decently fast with both processors at 100%. I tried this with ROMS 2.1 and ROMS 3.0.
