Thorns we know of

2022-06-26T18:19:13Z

Tootle:

There are more public thorns (as in has an open source license) around than just those in the Einstein Toolkit. This might be because the thorn does not satisfy our quality standards or because it is not yet clear if the thorn would be used by a number of users.

For non-thorn codes, please see: [[Additional resources|Additional resources]]

If you have thorn that you would make public and maybe entually see included in the Einstein Toolkit, you are encouraged to list it here, together with a short description of what it does. Our hope is to provide a list of (most of) the available Cactus thorns. Having a thorn listed here also makes it easier for us to estimate how much interest there is in it.

Source code repositories are vastly preferred over just source tarballs since they make it much easier for your users to contribute back changes.
If you are not yourself able to host a repository you might consider one of the public source code hosters such as those listed on [https://en.wikipedia.org/wiki/Comparison_of_open_source_software_hosting_facilities Wikipedia]. Some of [mailto:users@einsteintoolkit.org us] have used GitHub in the past as well as BitBucket (but see ticket [https://trac.einsteintoolkit.org/ticket/697 #697] for issues with it). For subversion packages the Cactus team is offering to host svn repositories for thorns for various projects, groups, or people on the Cactus [https://svn.cactuscode.org subversion server].

Thorns we know of

2022-06-26T18:18:14Z

Tootle: Updated FUKA urls for consistency

There are more public thorns (as in has an open source license) around than just those in the Einstein Toolkit. This might be because the thorn does not satisfy our quality standards or because it is not yet clear if the thorn would be used by a number of users.

For non-thorn codes, please see: [[Additional resources|Additional resources]]

If you have thorn that you would make public and maybe entually see included in the Einstein Toolkit, you are encouraged to list it here, together with a short description of what it does. Our hope is to provide a list of (most of) the available Cactus thorns. Having a thorn listed here also makes it easier for us to estimate how much interest there is in it.

Source code repositories are vastly preferred over just source tarballs since they make it much easier for your users to contribute back changes.
