[Paraview] Paraview ( MPICH, OpenMPI or LAM/MPI )

[Cally]

Hi guys,

I managed to install all the requirements for Paraview, I have
installed MPICH and LAM/MPI and am using 2 node machines ( a beawoulf
cluster ). Anyway, just a curious thought, and some questions that i
would really like to know as I will be shifting this into a 32 node
cluster.

a) I have configured LAM/MPI, but am having problem with the
MPI_INCLUDE_PATH and MPI_LIBRARY  not found. I have installed it into
my home directory, and I am not root.

b) Should I just switch to OpenMPI, also.. ( how does it make a
difference to the installation of Paraview ), Any notes or tutorial I
can read, i have tried searching the net but there is not much.

c) do I really need an extra mpi library or is MPICH good enough.

Sorry, if the questions are too basic but i really need help. And I
think this first phase is really important for me, i cant change the
MPI at the last minute ). I will be configuring  it on an
heterogeneous cluster later on.

Thanks.
