Community Earth System Models (COSMOS) collaboration project builds on Max Planck Institute for Meteorology's general circulation models ECHAM5 and MPI-OM, and PRISM's OASIS3 coupler. CSC's CoMS project provides support for compiling and running COSMOS and it's constituent models on available computing platforms.

COSMOS at CSC's environment

Below are short instructions on howto get started with ECHAM5, MPIOM and COSMOS on CSC's HP Operon cluster murska.csc.fi.

# COSMOS Earth System Model
#
# Adaptation of the PRISM Standard Compiling Environment (SCE) and
# Standard Running Environment (SRE) to CSC environment in
# murska.csc.fi.
#
# Contains a minimal patch to compile and run small test runs
# of standalone models echam5 and mpiom, and the coupled model
# cosmos-ao.
#
# Source and input files needed from MPI-M:
#   (1) cosmos-1.0.0.tar
#   (2) input_echam5_T31L19.tar
#   (3) input_mpiom_GR30L40.tar
#   (4) input_cosmos-ao_T31L19_GR30L40.tar
#
# Patch for murska.csc.fi:
#   (5) cosmos-1.0.0-csc.patch
#
# juha.lento (at) csc.fi
#

# Login to murska.csc.fi

# Copy files (1) - (5) to $WRKDIR

# Prepare source
