Hi everyone,
I want to install OpenMPI on my Ubuntu 8.10 64bit PC. My first attempt to
install it was through the ubuntu package manager. From the synaptic manager
I found, downloaded and installed OpenMPI 1.2.7 version. Unfortunately the
installation package did not allow any configuration options in order to
define the desired compilers as F77,F90 etc and when I type mpif77 for
example I get the message
--------------------------------------------------------------------------
Unfortunately, this installation of Open MPI was not compiled with
Fortran 77 support. As such, the mpif77 compiler is non-functional.

--------------------------------------------------------------------------

I tried to uninstall this version of the MPI but I was not able to
completely remove it. To explain what I mean : after removing it through the
synaptic manager when I type the mpirun command in terminal I get the same
message as above. Can anyone tell me what files do I have to remove so that
I can completely clean my PC from that version and install an other version
which will allow customizations? Alternatively is there any way to define
the compilers after the MPI installation?

Now regarding a new clean installation of OpenMPI : What version do you
suggest me install on my pc? Is the latest version (1.3.2) stable enough?
As far as I have read in the readme/ installation documents to install the
version 1.3.2 I have to run the ./configure command adding the
--prefix=/installation/location and F77=77 fortran compiler ,etc (where
fortran compiler is just the compilers name e.g. ifort not its location on
the filesystem) and after that make all install, is that correct? Can I
install OpenMPI at any directory or should I install it in the compiler's
installation path?
 Do I have to make any other customization in the .bashrc in order OpenMPI
to operate? If yes what do I have to add ?

I am a relatively new user in linux so detailed instruction would be
appreciated. I am looking fowrward hearing from anyone who could help.
Thanks in advance.
