| Dedalus is "A flexible framework for spectrally solving differential equations."[https://dedalus-project.org/]
| | Moved to https://kb.wisc.edu/math/internal/123324 |
| | |
| Our research servers have version 3-beta(from the [https://github.com/DedalusProject/dedalus/ Git master branch] of 19 May 2020).

| == Setting up the environment ==
| |
| # Log in to a [https://kb.wisc.edu/math/internal/page.php?id=114567 research server] or Linux workstation.
| |
| # Run: '''source /usr/local/dedalus/init'''
| |
| # You will see that the prompt is prefixed with '(dedalus3)'.
| |
| # You can now run Python3 code using the Dedalus modules.
| |
| | |
| == Notes ==
| |
| As per the [https://dedalus-project.readthedocs.io/en/latest/pages/performance_tips.html?highlight=NUMEXPR_MAX_THREADS#disable-multithreading Dedalus documentation] the following environment variables will be set when the Dedalus environment is activated:
| |
| OMP_NUM_THREADS=1
| |
| NUMEXPR_MAX_THREADS=1
| |
| | |
| See:

| |
| * https://numexpr.readthedocs.io/projects/NumExpr3/en/latest/user_guide.html#threadpool-configuration
| |
| | |
| This could have an effect on other code/applications you might run from the Dedalus environment.

| == FAQ ==
| |
| | |
| === I think there is a problem with the installation ===
| |
| The first thing you should do is to run the regression tests that are built in to Dedalus. Depending on the outcome you may want to contact IT to investigate.
| |
| | |
| To run the tests do this:
| |
| | |
| <code>pytest --workers=1 -k 'not ncc' /usr/local/dedalus/miniconda3/envs/dedalus3/lib/python3.10/site-packages/dedalus/tests/</code>
