SCC19 Workflow

This workflow automates the computation of Normal Mode using pEVSL (parallel EigenValue Slicing Library) for the planetary models generated by Planetary Model Builder.

Workflow

The workflow consists of three actions:

• build. Builds pEVSL and its test-cases, and installs NormalModes application. These can be built using [intel MKL][mkl] or [OpenBlas library][oblas]. You can choose the preferred library by using the different makefiles present in /makeconf directory.

• test. Runs tests on pEVSL.

• run. Compute the Normal Modes for a constant perfectly spherically symmetric pure solid ball has a size of the Earth; using the Model from demos. The global_conf file in that file can be modified in order to run other examples.

Environment

• NUM_BUILD_JOBS. The number of jobs to run while building the libraries via [make][make].
• MPI_NUM_PROCESSES. The number of processes on which to run while executing the MPI job.

Execution

This workflow runs on the host machine environment and can be executed with the Popper CLI tool. For a version of this workflow in a containerized environment, see here. The following executes this workflow:

git clone --recursive https://github.com/ivotron/scc19-workflows
cd scc19-workflows/workflows/containerized

popper run

NOTE: The --recursive flag is required in order to download the https://github.com/js1019/pEVSL and https://github.com/js1019/NormalModes projects, which are submodules of this repository.
