I successfully compiled the cxxhello program from the LAM examples but
get a run time error when I run it. Lamboot starts correctly, lamnodes
works as do programs compiled with mpicc.
I'm running lam, version 7.2b1svn10376 from the SVN repository, compiled
with the Intel compiler, version 9.1.043. I see the same thing with
version 7.2b1svn10366.
The platform is a Fedora Core 6, 32-bit Athlon system,
The error from cxxhello is
% mpirun C ./cxxhello
MPI_Comm_rank: invalid communicator: Invalid argument (rank 0,
MPI_COMM_WORLD)
Rank (0, MPI_COMM_WORLD): Call stack within LAM:
Rank (0, MPI_COMM_WORLD): - MPI_Comm_rank()

MPI_Comm_rank: invalid communicator: Invalid argument (rank 1,

One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 27324 failed on node n0 (192.168.1.3) with exit status 22.

This has worked with the version 8 Intel compiler.
Am I missing some vital flag to icpc? Any suggestions?
Anthony.
