[RegCNET] Error in Parallel Run!

[bixq]

Dear all:

When you install your LINUX, sometimes the mpif90 (or mpif77) is 
installed, then we you type

mpif90 -V

you'll see this mpif90 is created by using g95 (GNU FORTRAN) compiler.

But the present version of RegCM3 doesn't fully work with g95, so you have
to reinstall the OpenMPI library of using ifort compiler.

You can see the steps to install openmpi at:
https://lists.ictp.it/pipermail/regcnet/2009/001880.html

Nikolaos Vidiadakis's comment is correct, mpif90 is just the f90 compiler and
with the proper compiler option for specify the environment and library 
of MPI (MPICH or openmpi), if the compiler is provided by the computer 
vendor, it could also be just f90 (like SGI Altix 4700).

Regards,
Xunqiang Bi
