Instructions

Documentation for the 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!

Weekly Users Call

• Each week Thursday 9am US central time
• The link for the call is: https://lsu.zoom.us/j/631356683
• The next call's meeting agenda is on this wiki too.

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 Dependent Task Scheduler
• Education and Outreach
• IllinoisGRMHD
• Numerical Relativity in Spherical Coordinates
• 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) 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.
