Charm++ parallel programming system

["Eduardo Rocha" <erocha.ssa AT gmail.com>]

Dear Mr. Bohm,

Thanks for your reply.

I am using Debian 4.0 in a Xeon cluster. My libc is 2.7 as yours, my
gcc is 4.3.1 and my kernel is 2.6.25. I am also using g95 64bits 0.91
(stable version).

My problem is that even a very simple Fortran/MPI program does not
execute with AMPI/Charm in that environment. It does not produce any
error, but it does not produce any output either. This problem is
similar to what happens if you do not change the declaration "PROGRAM"
to "SUBROUTINE MPI_MAIN" in a Fortran program.

I can execute C/MPI programs in that environment and I could execute
Fortran/MPI programs in another cluster, which had a different Linux
distribution (an old one). I did not know I could use gfortran. I will
try it.

By the way, my objective is to make some simulations with
BigSim/BigNetSim. I want to execute some NAS benchmarks in these
simulators. I would like to compare the simulated results with those
produced by a real cluster. Our cluster is an Ethernet/Multicore
Cluster. Where can I find information to model this type of
interconnection?

Best regards,

Eduardo
Brazil
