I am using only F77 with PVM in Linux or other machines, because I don't
know well about F90 and there is no free compiler in Linux. But someone
made the f90 wrapper for pvm. Try
http://www.epm.ornl.gov/pvm/pvm_home.html. You will find some
informations.

I suggest that you use Linux and if possible f90 complier for Linux.
This is more cheaper than using NT with PVM. if you want to use PVM on
NT machines, there are many problems than Linux.
First, you need to buy or to get free virsion of rsh or rsh daemons for
NT
Second, communication speed of NT PVM is slower than Linux. You can find
some modifications on NT machines. Try this site.
http://www-csag.cs.uiuc.edu/projects/hpvm.html. This is NT Cluster.

Sorry for my poor English and dumb answers.

Last reason of my not using NT is my hating of Micro$oft.
