<P><FONT SIZE=2> Hi,<BR>
# Can you run non-MPI programs using mpiexec (mpiexec -n 2 hostname) ?<BR>
# Can you compile and run the hello world program (examples/hellow.c) provided with MPICH2 (mpiexec -n 2 ./hellow)?<BR>
# 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)?<BR>
# How did you find that mpiexec kills the sshd process (We typically ssh to unix machines and run mpiexec without any problems) ?<BR>
<BR>
Can you run smpd/mpiexec in debug mode and provide us with the outputs (smpd -d / mpiexec -n 2 -verbose hostname) ?<BR>
<BR>
Regards,<BR>

<BR>
Hi,<BR>
<BR>
I am cross-compiling mpich2-1.0.8 with smpd for Khepera III mobile robot.<BR>
<BR>
This mobile robot has a Korebot board which is an ARM-based computer with a Linux operating system.<BR>
<BR>
The cross-compilation was fine.<BR>
<BR>
Firstly, I logged in to Korebot through ssh.<BR>
Secondly, I started smpd.<BR>
Thirdly, I ran mpiexec to execute an MPI program (cpi) that comes with the package.<BR>
<BR>
The result was correct, but when mpiexec was finished, the ssh connection to the Korebot was closed.<BR>
I found that mpiexec kills the sshd process through which I was remotely connected to Korebot.<BR>
<BR>
I've been looking for the cause, but still have not found any clues.<BR>
<BR>
Could you give me any ideas to solve this problem?<BR>
<BR>
Thank you,<BR>
<BR>
Yu-Cheng<BR>
