admin items
===========

* will try and find a time that lets both CET and PT attendees attend
* only option would seem to be Monday 11am ET, will have a call in that
  slot to sort this out
* in the call today a single slot could not be found, so we will
  alternate Mon 11am and Thu 4pm ET

updates
=======

* AsterX paper was resubmitted by Jay
* Erik will integrate changes to CarpetX found during GRaM-X workshop
  into main, includes changes for new versions of ADIOS2 and openPMD
* Allen is looking for any experience compiling FUKA on db1, needs
  Boost, will work with Steve on this via Telegram
* Lucas found that the current CarpetX / ODESolvers code triggers
  growth of high frequency unstable structures that grow to 1e9 from
  noise in a couple hundred steps; only on multi-MPI rank CPU runs or
  GPU runs; Erik suggests to check after a single time step; Lucas has
  poisoning turned on; Roland would like to include a fix for this in
  the upcoming ET release (Nov 29th)
* Roland suggests collecting scripts used by developers to load openPMD
  files using Python
* Liwei asked about a Python interface to Silo. One is included in
  Silo: https://silo.readthedocs.io/python.html 
* Cheng-Hsin is making progress with NewRadX pull request, can be
  applied in CarpetX/Loop, SpacetimeX/NewRadX pull request is dependent
  on this one, would want to include in November release
* Jay and Allen are working on GPU enabled tabulated EOS code
* Liwei is currently working on ReadInterpolate ported to CarpetX, no
  updates on subcycling work

Yours,
Roland
