Thorns we know of

There are more public thorns 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.

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 Wikipedia. Some of us have used GitHub in the past as well as BitBucket (but see ticket #697 for issues with it).
