Up to now I have bought the following software of intel:
1) Intel fortran compiler 9.0
2) math library 7.0.

Now I have questions as following
1) If I want to use parallel calculation function, i.e. mpi module,
what kind of software do i need to buy? I didn't find the mpi fortan compiler of intel. If Intel has, where could I found that?

2) what's difference of fortran 8.0 and fortran 9.0?

Your advices is greatly appreciated.

Regards,
David,

There is not a separate MPI compiler. You use the standard compiler with the MPI library of your choice (mpich, etc.)

Version 9.0 has many improvements and bug fixes over 8.0.

You can go here http://www.intel.com/cd/software/products/asmo-na/eng/cluster/mpi/240842.htm?prn=y
to download Intel MPI. It comes set up for Intel compilers (e.g. mpiifort) as well as gcc and g++. gfortran is a simple matter of replacing g77 with gfortran in the mpif77 script.
If you use a public MPI, you must reconfigure so as to use Intel compilers.
All of these MPI implementations use a compile script which invokes your installed compiler.
