Usage: mpiexec [<args>] <executable> [<exe args>]...
   or: mpiexec [<args>] -config[=]<file>
  -n <numproc> : use only some of the allocated processors
     Default behavior allocates one process per allocated processor.
  -verbose : be verbose about mpiexec operation
  -nostdin : do not listen to stdin, allowing process to go into background
  -allstdin : send stdin to all processes (default just proc #0)
  -nostdout : do not redirect stdout/stderr, but let pbs accumulate it
  -comm (gm|p4|ib|mpich2|lam|shmem|emp|none) : choose MPI (default mpich-gm)
    -mpich-p4-[no-]shmem : for MPICH/P4, specify if the library was
                           compiled with shared memory support (default yes)
  -pernode : allocate only one process per compute node
  -nolocal : do not run any MPI processes on the local node
  -transform-hostname[=]<sed expression> : use alternate names for MPI
  -tv : debug using totalview (ensure it is in your path)
  -kill : kill other processes if any one process exits
  -config[=]<file> : use heterogenous node specification file ("-" for stdin)
  -version : show version information
