[mpich-discuss] mpiexec kills the remote login shell

[Jayesh Krishna]

 Hi,
# Can you run non-MPI programs using mpiexec (mpiexec -n 2 hostname) ?
# Can you compile and run the hello world program (examples/hellow.c)
provided with MPICH2 (mpiexec -n 2 ./hellow)?
# How did you start smpd (the command used to start smpd) ? How did you
run your MPI job (the command used to run your job)?
# How did you find that mpiexec kills the sshd process (We typically ssh
to unix machines and run mpiexec without any problems) ?

 Can you run smpd/mpiexec in debug mode and provide us with the outputs
(smpd -d / mpiexec -n 2 -verbose hostname) ?

Regards,
Jayesh

Subject: [mpich-discuss] mpiexec kills the remote login shell

Hi,

I am cross-compiling mpich2-1.0.8 with smpd for Khepera III mobile robot.

This mobile robot has a Korebot board which is an ARM-based computer with
a Linux operating system.

The cross-compilation was fine.

Firstly, I logged in to Korebot through ssh.
Secondly, I started smpd.
Thirdly, I ran mpiexec to execute an MPI program (cpi) that comes with the
package.

The result was correct, but when mpiexec was finished, the ssh connection
to the Korebot was closed.
I found that mpiexec kills the sshd process through which I was remotely
connected to Korebot.

I've been looking for the cause, but still have not found any clues.

Could you give me any ideas to solve this problem?

Thank you,

Yu-Cheng
