The default configuration is T42L26, Eulerian dynamics,## CLM2 land model, and CSIM4 ice model.#### Setting LoadLeveler options for batch queue submission.## @ class is the queue in which to run the job.##     To see a list of available queues, type "llclass" interactively.## @ node is the number of nodes. @tasks_per_node should be set to 1 because##     of the hybrid OpenMP/MPI configuration of CAM.  The number of nodes should##     be a power of 2, up to a max of 16 for T42.## @ output and @error are the names of file written to the directory from##     which the script is submitted containing STDOUT and STDERR respectively## @ job_type = parallel declares that multiple nodes will be used.## @ network.MPI: Has to do with network connection between nodes.  Best to leave alone.## @ node_usage = not_shared acquires dedicated access to nodes for the job.## @ queue tells load leveler to submit the job#@ class          = com_reg#@ node           = 2#@ tasks_per_node = 1#@ output         = out.$(jobid)#@ error          = out.$(jobid)#@ job_type       = parallel#@ network.MPI    = csss,not_shared,us#@ node_usage     = not_shared#@ queue## POE Environment.
