Hi Lenny
After removing the max-slots entries,
i could do
mpirun -np 4 -hostfile th_02 -rf rf_02 ./HelloMPI
without any errors.
But can you explain what the meaning of the max-slots entry is?

can you try not specifiyng "max-slots" in the hostfile.
if you are the only user of the nodes, there will be no oversibscibing of
the processors.
This one definetly looks like a bug,
but as Ralph said there is a current disscusion and working on this
component.

Is there an explanation for this?
I believe the word is "bug". :-)
The rank_file mapper has been substantially revised lately - we are
discussing now how much of that revision to bring to 1.3.4 versus the
next major release.

I am not sure if it has something to do with Open MPI at all.

Hi Lenny
Thanks - using the full names makes it work!
Is there a reason why the rankfile option treats
host names differently than the hostfile option?
Thanks

Hi
This message means
that you are trying to use host "plankton", that was not allocated via
hostfile or hostlist.
But according to the files and command line, everything seems fine.
Can you try using "plankton.uzh.ch" hostname instead of "plankton".
thanks
Lenny.
