Running a Existing Setup

Prepackaged runs are common for testing SCHISM on a new system or rerunning a model from another user delivered as a bundle. In this case the user will have obtained a complete set up as a “tarball” (tar.gz) file or copies the run using the rsync command (don’t use copy command cp). See Linux hints.

The steps are:

☐ Set up the environment and compile schism

☐ Untar the archived run

☐ If the atmospheric files are packaged separately, reestablish the linkage using the instructions in the readme file.

☐ Compile the model using instructions on the VIMS website or precompliled binaries for Windows*

☐ Most clusters use a job manager and you submit to queue. Usually you need to adapt

☐ schism.sh to point to executable and load dependencies

☐ launch files such as launch.pbs (user name, number of cores and cpus per core, name of run)

☐ Create a directory called outputs

☐ Take care of any ‘gotchas’ such as making sure there is a directory named ‘outputs’ and that stack limits are disabled.

* Windows is good for learning but not typical for full Delta runs
