* Any First Business
* search for next ET release manager [RH]
Steve, Yosef is the next release manager. And next release manager is
his deputy, who is Roland.
* FLRWSolver inclusion [RH]
Roland, have not heard from Helvi, and need help reviewing this---last
time not enough time for the review. Helvi and Hayley need to be poked
and check on progress---Peter will do that.

* ET hackathon [RH]
Schedule the hackathon? Steve, requests that we do not have it on a
Tues or Thurs. Steve, we have a good idea of what the bugs are and
should go ahead with it. Roland, we should have a pre-selection of
tickets and bugs for people to work on. Steve, we have done that.
Steve and Roland added to some tickets "hackathon". Fixing a ticket
miggt be 10 minutes but the testing might be an hour or so. It will be
on Wednesday, Feb 2nd, start at 11am CST. Think of it as most of a day
with people coming in and out.
* ET presentation series [RH]
We should keep it up. See page
Simfactory Setup and Kuibit tutorial seem to be next on the list.
Steve, would like to see another NRPY tutorial but he wants time to work
on that. Llama presentation would be good; unsure if the 13 patch is
working. Roland, 2D visualization is covered by Kuibit, so will remove
those. Turn the Mulitpatch into a TBD. In 3-4 weeks, Roland can do the
Simfactory tutorial, time to organize it. Simfactory Setup scheduled
for Thursday, Feb 10th, during the meeting/telecon.
* ET Jenkins server retirement [RH]
Roland, status update, it ran on a virtual machine on NCSA and that has
been retired. So we do not have Jenkins server running, but there is
sort of a continuous testing on GitHub. Looked at yesterday and looked
"wonky" so we may not have as nice a continuous integration testing
server. May not want a Jenkins server though because it requires such
extra effort. Zach, does GitHub actions do all the tests? Roland, it
does, and takes 1/2 - 1 hour. What is wonky is it claims 250 commits
since the last release. It is still triggering, and have a lot of
computer time because of the educational discount at GitHub.
See the students work at https://mojamil.github.io/einsteintoolkit/ ,
and can contribute or comment at
Would be good for someone to help out making the GitHub actions better here.
* Suggestions for new inclusions to consider for the ET [RH]
** Self force code [RH]
Peter, we can have something for the next release. Samuel Cupp has
completed evolution in Schwarzschild. Need to make sure the code is
** Full reprimand code / thorn [RH]
*** tabulated hot EOS in Reprimand?
Roland was reviewing it. Roland right now we have a RePriMand library
that is not used by anything. We should make sure that something uses
it. The build process requeres changes / fixes, Wolfgang, the Meson
build system being used will always assume you can find the external lib
by pgkconfig whtihi is not true on clusters. Though it has tabulate EOS
is for the cold matter, and not hot, so hybrid EOS. Not godo for
micro-physics. Need to keep up-to-date what they are doing. It si
Con2Prim but has its own EOS framework. The Con2Prim routing is
somewhat indep of the EOS, but you stell need to make sure the EOS gives
the guarantees that the Con2Prim requires
** Major update to Baikal
Zach, mostly a modernization of how the thorn is constructed in NRPy.
Functionally identical (maybe one bug fix) to current thorn.
question on mailing list]
Current link shows all the emails in the last month, a bug right now.
