* Next release is in April 2020.
* Update on potential codes to be included for next release
** Baikal ETK code from Zach
Zach has not had time to make the change where at run time you can choose different kernels, 8th order or less, and whether you want to add the Tmunu in. Six kernels to ask, needs time to pull that together. It does work and they use it. Helvi is reviewing it.
** Upgrade to Illinois GRMHD
Extends the capabilities to use piece-wise polytrope and hybrid EOS, agrees with old version. Ready for review. No changes planned; documented in Jupyter notebooks. Should pass all the code / unit tests in ETK. Would like to extend to piece-wise polytrope initial data for single TOV star. Roland was original reviewer and the new version feature update is the piece-wise polytrope and the hybrid EOS---you run the Jupyter notebooks and they generate the GRMHD thorn.
** Zach also has a TOV code which he might want to contribute
Nrpy TOV Thorn (Nrpy TOV ID) could come into play. Leo Vernick (lead author, back in Brazil) has a C code version. Run Numpy, and Nrpy puts it on the grid, even deals with star surface, avoids it and avoids Gibbs phenomenon. Has a student optimizing the C code generation from Nrpy, and doing an extra pass at the post CSE output. Not able to speed up the C code generation, but have sped up the Nrpy code a lot. Needs a reviewer.
** Steve would like Presync in
** Peter says that he will have updates to the self-force code
Previously thought there was a problem with code, not behaving like previous version, but now believes it does. Will be minor updates / capabilities to reduce the window function to zero size, a distribution function source, that should be read by the next release. Nothing major after that fix.
* Workshop at LSU and registration page has been tested. Dates August 3-7, 2020. Has some money to support travel for students. Website at https://www.cct.lsu.edu/Einsteintoolkitworkshop . Steve looking for people to present and give tutorials. Zach has a student with interesting Nrpy Wave Toy that might be available.
* Steve wants to switch to Python3 for Simfactory (Python 2 no longer officially supported). hwloc fails to build on Master for generic config. Need to have locality setup correctly for Python3 to work, otherwise trying to interpret Unicode in PIP downloads fails with clear error message.
* For above additions to the ETK, create a ticket to add your code to Master branch by March so that it can get tested. Steve thinks there is a ticket for the Python3 conversion.
