Hello, 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.
