This looks fine to me.

It is definately not necessary on any P4 machines. I don't know about the
Opteron, perhaps the 32 bit compilation will solve the problems. Adding
"-Mvect=noassoc -Kieee" really really slows things down so it would be

I am running PGF90 v6.1-3 Workstation Edition. This is the latest version
the Portland Group compilers and is the one currently advertised on their
website. I have found a 32 bit machine with a very OLD version of the
Portland group compiler v3.2-4. I will try this out in a hour or so and

are the only two versions of the compiler I have access to unfortunately.
Maybe Kim has a slightly different version.

All the best
