[RegCNET] problem using different compiler..

[bixq]

Hi, Deepika:

You use Linux PC, right ?
It seems ifort has been well installed, now you have to install
subversion and openmpi,

It's easy for the installation of subversion.

To install openmpi, google and download the package (version 1.4.2
or the beta version). untar it and enter the directory.

1.
./configure CC=icc CXX=icpc FC=ifort F77=ifort F90=ifort F95=ifort
             --prefix=/opt/openmpi
make
make install

(you have to have the write-permission under /opt)

2. edit .bashrc (or .cshrc if you use tcsh) file, and add two lines:

export PATH=/opt/openmpi/bin:$PATH
export LD_LIBRARY_PATH=/opt/openmpi/lib:$LD_LIBRARY_PATH

You know, when you installed, you might already get mpif90 installed.
This mpif90 is based on g95 (or gfortran, sorry I am not sure). But you
know, Intel IFC is faster, so you'd better do the steps as I suggested.

That's all you have to do.
Good luck !
