== Discussion session ==

=== Proposed working groups review ===

==== WG1: interface with experiments (Sascha to lead) ====
==== WG2: performance (already exists) ====
==== WG3: maintainers club ====
* Ian to leave
* Helvi to join

==== WG4: matter codes====
* google doc exists (Bruno)
* no more updates since
* suggestion: to coordinate / merge with IllinoisGRMHD

==== WG5: Initial data ====
* low priority

==== WG6: outreach & education ====
* already exists

==== WG7: Datavault ====
* hosted at NCSA
* Qian has finished PhD and moved
* repository exits
* Sascha suggests to use internal LIGO format
* planning to get a student to continue working on it

=== Working groups update ===

==== Cosmology and particles (Helvi and Eloisa) ====
* Eloisa has left; volunteers welcome to join lead the group
* Goals: Modified theories, High-energy, cosmology, ...
* diverse team, different expertise. has people that work with other codes (not only ET based)
* idea is to match people doing theory and numerical development
* regular calls every first monday of month at 16h30 (UK, PT), 10h30 (CDT)
* idea is to move forward with specific projects
* everyone welcomed to join

==== Task scheduler (Erik, Steve, Sam, Roland) ====
* essentially Steve and Sam
* see Steve and Sam's talks in the workshop
* backwards compatibility
* figure out difficulties with AMR and then update ET thorns to use it
* future: automatic allocation of memory (in storage)

==== Education and outreach (Matt, Gab, Helvi) ====
* one call early this summer
* Steve wants to join and contribute jupyter notebooks with tutorial and such
* Gab working with undergraduate students
* for outreach: use ET logo in all movies done with ET for visibility
* generic.cfg should work out of the box in any computer outside of Macs.
* problem with Macs that it called "gcc" what is actually clang (which doesn't understand OpenMP, for instance).

==== IllinoisGRMHD (Zach) ====
* Zach has major contribution to upcoming release (five new thorns, more thorns proposed)
* very active team

==== Spherical coordinates ====
* not officially approved
* RIT internal
* should contact RIT folks

==== Performance and optimization (Erik, Roland, Helvi, Eric West) ====
* idea: make the code faster
* build infrastructure to easily check speed on new clusters and machines
* task based parallelism in Cactus
* someone needs to merge master with ianhinder/rkprol, benchmark, and take over
* many bits and pieces have already been implemented and pull requests exist to merge with ET master
* NRPy: see Zach's presentation
* lots of work being done, but mostly behind the scenes
* Helvi to do scaling and performance comparison with BAM, etc
* anyone interested welcome to join

=== Other items ===
* memory leak: Wolfgang to open ticket.
* list of papers to cite after running ET with some list of thorns.
* use something like joss for citations and credit?
* ETK waveform catalog

==Instructions==

Documentation for the [http://www.einsteintoolkit.org Einstein Toolkit] is a community effort and everyone is encouraged to contribute towards these pages. You need to login to the wiki to edit the documentation, to do this either

* if you already have a personal LDAP login with the CCT use this
* create you own login/password for the wiki (select local domain)

If you would like to make major changes to these pages please discuss first on the users@einsteintoolkit.org mail list.

Thanks for your contributions!

== Einstein Toolkit Working Groups and Development Teams ==

The idea of establishing working groups for the Einstein Toolkit was discussed at the Summer 2017 Workshop at NCSA, and is now being implemented. The initial [[ET Working Group Policies and Procedures]] document has been discussed and approved. New working groups should be proposed using the [[Working Group Template]].

'''Planned Groups''':

* [[Working List of ET Groups]]

'''Established Groups:'''

* [[Cosmology and Particles]]
* [[Data Dependant Task Scheduler|Data Dependent Task Scheduler]]
* [[Education and Outreach working group|Education and Outreach]]
* [[IllinoisGRMHD Working Group|IllinoisGRMHD]]
* [[Numerical Relativity in Spherical Coordinates]]
* [[Working Group on Performance Optimization|Performance Optimization]]

==Einstein Toolkit Seminars==

It would be nice to organize a semi-regular series of talks with topics of general interest. This should include
not only people from within the Einstein Toolkit. The ET web page already contains a (currently quite short)
[http://einsteintoolkit.org/seminars/ list], and now it is time to propose upcoming talks. In order to record and
story voiced proposals, please use the wiki page [[Einstein Toolkit Seminar Proposals]].
