Hello Christoph,

When ompi is configured with the lanl/cray_xe6/optimized-nopanasa,
you have to use the 'aprun' launch command.

Trying running your HelloWorldMPI as

aprun -n 1 HelloWorldMPI

Also, this particular config of ompi will not run in the 'cluster compatability'
mode environment.

Hope this helps,

Howard

I just tried to use Open MPI 1.7a1r27416 on a Cray XE6 system. Unfortunately I 
get the following error when I run a simple HelloWorldMPI program:

$ pirun HelloWorldMPI
App launch reported: 2 (out of 2) daemons - 0 (out of 32) procs
...
[unset]:_pmi_alps_get_appLayout:pmi_alps_get_apid returned with error: Bad file 
descriptor
[nid01766:20603] mca_oob_tcp_init: unable to create IPv4 listen socket: Unable 
to open a TCP socket for out-of-band communications
...


The installation was configured with the following command:

./configure --with-platform=contrib/platform/lanl/cray_xe6/optimized-nopanasas 
--prefix=$HOME/bin/mpi/openmpi/1.7a1r27416
you are doing it local on the headnode only? It includes --with-alps by the 
platform file and there is the command `aprun` instead of `mpiexec` in the 
jobscript on a Cray. Maybe the allocation needs to be granted first.

I would be very happy if anybdy has an idea, what I could have missed during 
installation/runtime.

Thanks in advance.

Best regards
Christoph
