• Support: The Einstein Toolkit provides support through various channels.
  • Tutorials: The Tutorial for New Users leads through your first steps and more or you can use the read only version to try it at home.

  • Documentation: Components in the Einstein Toolkit often contain documentation. E.g., the Cactus ThornGuide provides a single guide for all the thorns. You can acess the complete Einstein Toolkit Thorn Guide and other supporting documents below.

Bug Tracker

Issues (bugs, wish-list items, tasks) are recorded in a database. There they can be discussed, flagged, and assigned to developers. Don't hesitate to report problem you might have found: reporting problems is the first step in helping to solve them.
