The Einstein Toolkit


Einstein Toolkit at ICERM Fall 2020, October 15th

The Einstein Toolkit is featured at the virtual ICERM 2020 Fall workshop on Advances in Computational Relativity. After having had a very successful initial tutorial there will be an Einstein Toolkit tutorial part II on Thursday, October 15th with the following schedule:

  • (12:00pm - 2:00pm EDT) NRPy+ (Zach Etienne). NRPy+ is an open-source Python code that converts expressions written in Einstein-like notation into highly optimized C/C++ code, using the powerful computer algebra package SymPy as a backend.
  • (2:15pm - 4:00pm EDT) Writing your own Einstein Toolkit thorns (Steve Brandt). This tutorial will show you how to extend the Einstein Toolkit.
Please register if you plan to attend.

New Einstein Toolkit Release

There is a new Einstein Toolkit release, the "Turing" Release. Please check the release notes for details.

Weekly telecon

Join us at the weekly Einstein Toolkit phone call at 9:00 am US central time on Thursdays.


The Einstein Toolkit is a community-driven software platform of core computational tools to advance and support research in relativistic astrophysics and gravitational physics.
