The name of the launcher is "rsh", but it actually defaults to trying
to fork/exec ssh.
Unfortunately, your backtrace doesn't tell much because there are no
debugging symbols. Can you recompile OMPI with debugging enabled and
send a new backtrace? Use:
./configure CFLAGS=-g ....

Does mpirun start rsh?? I think I need ssh instead of rsh.

I'm sorry -- I wasn't entirely clear:
1. Are you using a 1.0 nightly tarball or a 1.1 nightly tarball? We
have made a bunch of fixes to the 1.1 tree (i.e., the Subversion
trunk), but have not fully vetted them yet, so they have not yet been
taken to the 1.0 release branch yet. If you have not done so already,
could you try a tarball from the trunk?
http://www.open-mpi.org/nightly/trunk/
2. The error you are seeing looks like a proxy process is failing to
start because it seg faults. Are you getting corefiles? If so, can
you send the backtrace? The corefile should be from the
$prefix/bin/orted executable.
3. Failing that, can you run with the "-d" switch? It should give a
bunch of debugging output that might be helpful. "mpirun -d -np 2
./test", for example.
4. Also please send the output of the "ompi_info" command.

(there were some SVN commits last night after the nightly snapshot
was
made; I've just initiated another snapshot build -- r8085 should be
on
the web site within an hour or so)

Hi,

I am using openmpi-1.0rc4 and running on Linux Redhat Fedora Core
4.
The kernal is 2.6.12-1.1456_FC4. My building procedure is as
below:
1. ./configure --prefix=/home/clement/openmpi --with-devel-headers
2. make all install
3. login root. add openmpi's path and lib in /etc/bashrc
4. see the $PATH and $LD_LIBRARY_PATH as below
[clement@kfc TestMPI]$ echo $PATH
/usr/java/jdk1.5.0_05/bin:/home/clement/openmpi/bin:/usr/java/
jdk1.5.0_05/bin:/home/clement/mpich-1.2.7/bin:/usr/kerberos/bin:/

[clement@kfc TestMPI]$ echo $LD_LIBRARY_PATH
/home/clement/openmpi/lib
[clement@kfc TestMPI]$
5. go to mpi program's directory
6. mpicc -g -o test main.c
7. mpirun -np 2 test
Any idea of this problem. Many thanks.
