Present: Roland, Erik, Bill, Peter, Steve, Lucas, Zach

reproducibility issues of data in BNS simulation ================================================

* Zach reports that IllinoisGRMHD also runs con2prim in post-recover variables * reports are that results depend on number of MPI ranks, maybe in IllinoisGRMHD or DNSData (SGRID) reader * Roland now has access to initial data files and code used, will test if initial data is read in differently on different MPI ranks and if checkpoint recovery is bit identical

upcoming ET possible inclusions ===============================

* Z4c, high priority

** test cases required ** https://bitbucket.org/einsteintoolkit/tickets/issues/2748/inclusion-of-z4c-i...

* BHaHAHA horizon finder

** timeline will depend on workload for APS April meeting ** so far code is closed source and cannot yet be reviewed ** volunteers for reviewer are looked for, Peter may volunteer ** https://bitbucket.org/einsteintoolkit/tickets/issues/2850/add-bhahaha-to-ein...

* CCE code to hook up to Spectre

** work is restarting in earnest this week ** no ticket yet

* possibly more modules for FLRWSolver

** Hayley is interested and has been provided with a timeline and will have items ready for initial review early March

* gallery example for Canuda (Axi-dilaton)

** Lucas completed the review, currently online at: http://einsteintoolkit.org/gallery/axidilaton/index.html ** example is complete

* gallery examples for Canuda, Fishbone-Moncrief, IllinoisGRMHD

** TBD

Yours, Roland
