Hi Sandra

It may be more complicated to install a new version of gcc
in your Red Hat 7.3 machine, than to upgrade Linux to something
more up to date.
You may open an endless can of worms of package
and library dependencies will be hard to resolve.
Red hat 7.3 is about 10 years old, a lot has
changed since then.

CentOS and Scientific Linux are free,
and very similar to Red Hat enterprise.
The current version is 6.3:

https://www.centos.org/
https://www.scientificlinux.org/

Another option is to install Ubuntu:

http://www.ubuntu.com/

The current stable version is 12.04.1, I think.

An (admittedly very sketchy) outline of the procedure is:

- backup your /home and any other data that you want to keep,
maybe to a large capacity pen drive, or copy to a DVD perhaps,
- download the ISO images (sites above, pick one),
- burn the ISO images to CDs or DVD (probably several CDs or one DVD),
- put the first CD or DVD on the CD/DVD tray,
- reboot the computer,
- follow the installation instructions,
Once the system is installed:
- add new users (yourself, maybe more), then
- restore the files you need from your backed-up /home,
- add any packages you may need (e.g. gfortran) with yum (CentOS, SL)
   or apt-get (Ubuntu).
- install mpich2

I hope this helps,
