Hello,
Thanks for the fast answer !
So i have to choose between MPICH-G2 ans MPIg.
Which one is the most relevant to use ?
It seems that MPIg works with the last WS-GRAM of GT4. Is it better to
use this one ?
Many thanks,
Yann

Dear Yann,
Yes, it is possible to do that. Both MPICH-G2 and MPIg are MPI
libraries designed to do precisely that - including automatically
automatically converting data in messages sent between clusters
with different architectures.
You can learn more about MPICH-G2 at www.niu.edu/mpi .
MPICH-G2 works only with pre-web services GRAM from the Globus Toolkit
(i.e., GT2).
You can learn more about MPIg (MPICH-G2's successor) via
anonymous ftp:
The tarballs and instructions to build are all available on
NIU's anon ftp server ftp.cs.niu.edu: pub/karonis/MPIg.
There you can find mpig-1.0.6p1.1.tar.{bz2,gz} (same source,
compressed differently) and index.html (build instructions).
MPIg works with the same pre-web services GRAM that MPICH-G2
does and it also works with WS-GRAM found in GT4.

Hello,
I would like to know if, with globus, i can run a parallel program
over 2 clusters (running gridengine) at the same time, with mpich
communications between the 2 clusters (and if the architecture is
different too).
I made a figure which expose what i want to do. Cluster A and Cluster
B may have different architectures.
Thanks,
Yann
