Problems with MVAPICH2
Some MVAPICH2 MPI installations on Oakley, Ruby, and Owens, such as the default module mvapich2/2.2 as well as mvapich2/2.1, appear to have a bug that is triggered by certain programs. The symptoms are 1) the program hangs or 2) the program fails with an error related to Allreduce or Bcast.
