Subject: [OMPI devel] segfault on host not found error.
From: Lenny Verkhovsky (lennyb_at_[hidden])
Date: 2008-03-31 07:13:27


I accidently run job on the hostfile where one of hosts was not properly
mounted. As a result I got an error and a segfault.

/home/USERS/lenny/OMPI_ORTE_TRUNK/bin/mpirun -np 29 -hostfile hostfile
./mpi_p01 -t lt
bash: /home/USERS/lenny/OMPI_ORTE_TRUNK/bin/orted: No such file or
directory

A daemon (pid 9753) died unexpectedly with status 127 while attempting
to launch so we are aborting.
There may be more information reported by the environment (see above).
This may be because the daemon was unable to find all the needed shared
libraries on the remote node. You may set your LD_LIBRARY_PATH to have
the
location of the shared libraries on the remote nodes and this will
automatically be forwarded to the remote nodes.
