Open MPI 1.6.5 does not have support for the XE-6. Use 1.7.2 instead. > machine has PMI2.1.4 and PMI4.0 (default). Which version do you There was a regression in PMI 3.x.x that still exists in 4.0.x that causes a warning to be printed on every rank when using mpirun. We are working with Cray to resolve the issue. For now use 2.1.4. See the platform files in contrib/platform/lanl/cray_xe6. The platform files you would want to use are debug-lustre or optimized-lusre. BTW, 1.7.2 is installed on Cielo and Cielito. Just run: module swap PrgEnv-pgi PrgEnv-gnu (PrgEnv-intel also works) module unload cray-mpich2 xt-libsci module load openmpi/1.7.2 -Nathan Hjelm Open MPI Team, HPC-3, LANL
