 More fun. Parallel jobs can be submitted over ethernet interconnects but will not achieve the performance of Infiniband interconnects ofcourse.  OpenMPI is a nice MPI flavor because software compiled with it automatically detects if the host has an HCA card or not and will allocate the appropriate libraries. So in order to compile, or run, some OpenMPI examples we need the following:
-  * yum install libibverbs; pdsh yum install libibverbs -q -y
+  * yum install libibverbs
+  * pdsh yum install libibverbs -q -y
   * yum install gcc-c++
