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