• Runs e.g., MPI jobs (supersedes MPI universe)
• Requires dedicated members of a pool — dedicated machines never vacate executing jobs (not suitable for desktop machines).

  universe   = parallel
  executable = my_mpi_prog
  
  log    = my_mpi_prog.log
  input  = my_mpi_prog.data
  output = my_mpi_prog.out.$(NODE)
  errir  = my_mpi_prog.err.$(NODE)

  machine_count = 4

But why?

• Why not simply use a traditional batch system?
