[mpich-discuss] mpiexec crash

[Cherukumilli, Vasu]

Hi,

Was wondering if you guys had any insight in to this assert failure. We are seeing this intermittently.

The mpiexec command we are executing is similar to the one pasted below:

mpiexec  -n 1 <exec1>  :  -n 1 <exec2> :  -n 1 <exec3> :  -n 1 <exec4> :  -n 1 <exec5> :  -n 1 <exec6> :  -n 1 <exec7>

Crash that we are seeing:

No such file or directory. (errno = ENOENT)
Command exited with non-zero status 20

Thanks,
