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]

# The root to a location where the mesh_database, initial_condition_database,
# and bathymetry_database for MPAS-Ocean will be cached
ocean_database_root = /lcrc/group/e3sm/public_html/mpas_standalonedata/mpas-ocean

# The root to a location where the mesh_database and initial_condition_database
# for MALI will be cached
landice_database_root = /lcrc/group/e3sm/public_html/mpas_standalonedata/mpas-albany-landice

# 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 = impi

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

# the base path to system libraries to be added as part of setting up compass
system_libs = /lcrc/soft/climate/compass/chrysalis/system

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
