# This is a simple spifs run which fits on a single PC.
# OpenIFS with the T21 grid and 2 LES instances close to Barbados.
# This version uses the Amuse MPI channel.
# Demands an MPI implementation that supports comm_spawn.
# (Normally they do, Cray doesn't)

# number of GCM(OpenIFS) processes
N_GCM=1

# number of LES instances
N_LES=2

# number of LES processes per instance
LES_PROCS=1
