===== Batch System Configuration =====

Instructions on configuring the CIG edition of Pythia for a batch system such as LSF or PBS.

The following examples assume you are using CitcomS.  If you are using PyLith v0.8.2, replace 'CitcomS' with 'pylith3d'.

The configuration options below are suitable for inclusion in a ''CitcomS.cfg'' configuration file; for example:

  ~/.pyre/CitcomS/CitcomS.cfg

Be sure to set the ''command'' option under ''[CitcomS.launcher]'' to the proper command for launching MPI jobs on your cluster. This command will vary from cluster to cluster; the commands shown here are provided only as examples.

==== LSF ====

Here are example configuration options for LSF. These were tested on TACC's Lonestar system.

  [CitcomS]
  scheduler = lsf
  
  [CitcomS.job]
  queue = normal
  #queue = development
  
  [CitcomS.launcher]
  command = ibrun

==== PBS ====

Here are example configuration options for PBS. These were tested on NCSA's Itanium cluster.

You will have to set ''ppn'' to a value suitable for your cluster.

  [CitcomS]
  scheduler = pbs
  
  [CitcomS.launcher]
  command = mpirun -np ${nodes} -machinefile ${PBS_NODEFILE}
  
  [CitcomS.pbs]
  ppn = 2  ; processors per node
