Hi,

trying to run mtt I failed to run IBM spawn test. It fails only when using hostfile, and not when using host list.

( OMPI from TRUNK )

This is working :

#mpirun -np 3 -H witch2 dynamic/spawn

This Fails:

# cat hostfile
witch2 slots=4 max_slots=4

#mpirun -np 3 -hostfile hostfile dynamic/spawn
[witch1:12392] --------------------------------------------------------------------------
There are not enough slots available in the system to satisfy the 3 slots
that were requested by the application:
dynamic/spawn

Either request fewer slots for your application, or make more slots available
for use.
--------------------------------------------------------------------------
[witch1:12392] --------------------------------------------------------------------------
A daemon (pid unknown) died unexpectedly on signal 1 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.

mpirun: clean termination accomplished

Using hostfile1 also works

#cat hostfile1

witch2

Best Regards

Lenny.
