About

This repo contains resources to build and test Python packages for MDSplus on the PPPL linux cluster. The source code is located in /u/drsmith/mdsplus-python/ on the PPPL cluster.

The packages are tested with python2 and python3 and with modules nstx/mdsplus and nstx/mdsplus_alpha as appropriate. All building and testing is performed locally. A production installation can be reverse-engineered from the build target in Makefile.

Try it yourself on the PPPL cluster. Copy or clone:

$ git clone [email protected]:drsmith48/pppl-mdsplus-python.git

or:

$ cp --recursive /u/drsmith/mdsplus-python/ <destination directory>

Then run the shell script in the repo/directory:

$ source build.csh

Repo structure

• build.csh - configure modules and call Makefile to run build/test recipes
• Makefile - build Python packages with py2/py3 (as appropriate) and test packages with py2/py3 (as appropriate) by running test-mdsplus.py
• test-mdsplus.py - Python test script to import MDSplus and get MPTS data
• pylib/ - contains Python libraries from several MDSplus releases
  • pylib/mdsplus/ - Python library copied from /u/gtchilin/sandbox/mdsplus/R5_64/mdsplus
  • pylib/mdsplus_alpha/ - Python library copied from /usr/pppl/nstx/R6_64/mdsplus_alpha
  • pylib/v6.1.84/ - Python library from MDSplus v6.1.84
  • pylib/v7.0.71/ - Python library from MDSplus v7.0.71
  • pylib/v7.1.13/ - Python library from MDSplus v7.1.13

Other notes

1. The module nstx/mdsplus is MDSplus v5, and it only supports python2. Accordingly, the Makefile only builds and tests with python2.
2. The module nstx/mdsplus_alpha is MDSplus v6 and it supports python2 and python3. The Makefile builds a 'universal wheel' with python3 and tests with python2 and python3.
3. The file setup.py in the Python library for the module nstx/mdsplus_alpha contains an error that breaks the build. Simple fix: change the line setup(name=name, to setup(name=pname,.
4. PyPI (python package index) contains packages for MDSplus >= v6.1, so I obtained a few Python libraries from old MDSplus releases on Github. The libraries are in pylib/vX.Y.ZZ and the libraries work with the module nstx/mdsplus_alpha. The packages are built as a 'universal wheel' with python3 and tested with python2 and python3 in the Makefile.
