optimal linux flavor and fortran compiler?

[bchristo@email_arizona_edu]

Hello,

I am starting from square one for doing offline runs of CLM3.5. Could I get some advice on the best flavor of linux to use for offline runs?

I realize that CLM is only tested on pgf and Lahey compilers, which limits me to Debian, Fedora, Mandrake, RedHat, RHEL, Slackware, and SuSE

I notice from the CLM3.5 release page that CLM3.5 runs on the bangkok Linux cluster. What is the flavor Linux used here, and is there a recommended Linux/Fortran setup to use for running CLM?

Thanks,
Brad

Any combination should work but depending on your machine and compilers
few combinations can make setup easy.
pgi/lahley compilers on any linux you stated below shpuld not make any difference, ibm compilers on ibm machines(AIX/LINUX)

Thanks for the response.

Another related question: In the CLM3.0 User's Guide, it mentions that problems were encountered when the model was run using hybrid parallelism, or in bounds checking when running in debug mode. Does anyone know if this is still a problem in CLM3.5? I ask because I have a Pentium D processor (has 2 cores) and may stand to gain some efficiency by using OpenMP.

Thanks again,
Brad

clm3.5 is a tested code so it shouldn't cause any problem while running using hybrid parallism.. (i was running clm3 normally and it did not have any problem using hybrid parallelism)

Thanks. Another question:

What version of PGI (or Lahey) compilers are people using? I can afford to buy a license, but the subscription and updating of compilers on a yearly basis can get expensive. Hence I would like to buy a license for PGI version 7.1 and keep it for a while without worrying about updating frequently. I don't intend on agressively updating my version of Linux either.

Any new version should also work . i have used PGI 6.9 and 7.0
