Chrysalis

config options

Here are the default config options added when Chrysalis is automatically detected or when you choose -m chrysalis when setting up test cases or a test suite:

# The paths section describes paths that are used within the ocean core test
# cases.
[paths]

# A shared root directory where MPAS standalone data can be found
database_root = /lcrc/group/e3sm/public_html/mpas_standalonedata

# the path to the base conda environment where compass environments have
# been created
compass_envs = /lcrc/soft/climate/compass/chrysalis/base


# Options related to deploying a compass conda environment on supported
# machines
[deploy]

# the compiler set to use for system libraries and MPAS builds
compiler = intel

# the system MPI library to use for intel compiler
mpi_intel = openmpi

# the system MPI library to use for gnu compiler
mpi_gnu = openmpi

# the base path for spack environments used by compass
spack = /lcrc/soft/climate/compass/chrysalis/spack

# whether to use the same modules for hdf5, netcdf-c, netcdf-fortran and
# pnetcdf as E3SM (spack modules are used otherwise)
use_e3sm_hdf5_netcdf = True

Additionally, some relevant config options come from the mache package:

# The parallel section describes options related to running jobs in parallel
[parallel]

# parallel system of execution: slurm, cobalt or single_node
system = slurm

# whether to use mpirun or srun to run a task
parallel_executable = srun

# cores per node on the machine
cores_per_node = 128

# available partition(s) (default is the first)
partitions = debug, compute, high

Intel on Chrysalis

To load the compass environment and modules, and set appropriate environment variables:

source /lcrc/soft/climate/compass/chrysalis/load_latest_compass_intel_openmpi.sh

To build the MPAS model with

make [DEBUG=true] [OPENMP=true] ifort

Gnu on Chrysalis

To load the compass environment and modules, and set appropriate environment variables:

source /lcrc/soft/climate/compass/chrysalis/load_latest_compass_gnu_openmpi.sh

To build the MPAS model with

make [DEBUG=true] [OPENMP=true] [ALBANY=true] gfortran
