## Testing the installation
# Testing the installation

Testing can be done by:

```bash
$ mirgecom/examples/run_examples.sh mirgecom/examples/
```

## Running on systems with lots of nodes (>256)
On large systems, the file system can become a bottleneck for loading Python
packages. On these systems, it is recommended to create a zip file with the
modules to speed up the startup process. This can be done by specifying the
`--modules` parameter to `install.sh`, or by running `makezip.sh` after
installation.

See https://github.com/illinois-ceesd/planning/issues/26 for more details.
