-Dedalus is "A flexible framework for spectrally solving differential equations."[https://dedalus-project.org/]
-Our research servers have version 3-beta(from the [https://github.com/DedalusProject/dedalus/ Git master branch] of 19 May 2020).
-More information is available here:
-* https://dedalus-project.org/
-* https://dedalus-project.readthedocs.io/en/latest/
-* https://github.com/DedalusProject/dedalus/
-== Using ==
-# 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://www.openmp.org/spec-html/5.0/openmpse50.html
-* 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>
