Anvil
=====
Anvil is a set of nodes used by E3SM and its "ecosystem" projects on
``blues`` at `LCRC `_. To gain access to the
machine, you will need access to E3SM's confluence pages or the equivalent for
your ecosystem project.
config options
--------------
Here are the default config options added when Anvil is automatically detected
or when you choose ``-m anvil`` when setting up test cases or a test suite:
.. code-block:: cfg
# 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/anvil/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 = mvapich
# the base path to system libraries to be added as part of setting up compass
system_libs = /lcrc/soft/climate/compass/anvil/system
Additionally, some relevant config options come from the
`mache `_ package:
.. code-block:: cfg
# 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 = 36
# account for running diagnostics jobs
account = condo
# available partition(s) (default is the first)
partitions = acme-small, acme-medium, acme-large
# quality of service (default is the first)
qos = regular, acme_high
Intel on Anvil
--------------
To load the compass environment and modules, and set appropriate environment
variables:
.. code-block:: bash
source /lcrc/soft/climate/compass/anvil/load_latest_compass_intel_impi.sh
To build the MPAS model with
.. code-block:: bash
make intel-mpi
Gnu on Anvil
------------
To load the compass environment and modules, and set appropriate environment
variables:
.. code-block:: bash
source /lcrc/soft/climate/compass/anvil/load_latest_compass_gnu_mvapich.sh
To build the MPAS model with
.. code-block:: bash
make gfortran
