Subject Re: [DISCUSS] Meerkat as a Hama sub-module or sub-project
Date Mon, 28 Apr 2014 08:45:50 GMT

Sub-projects are generally frowned on.  Incubator projects can graduate
eventually to a top-level project, but starting a project as a sub is not
so good.  The incubator docs on this are pretty good reading.

But if the committer community for your real-time BSP is (or can be) the
same as the committer community for Hama itself, you might want to just
fold this new code directly into Hama itself.  No need in that case for a
separate project.

If the committer community is very different, then a separate project is

I don't think that the Hama development is such a high bandwidth thing that
splitting is required.  To my mind that says that joining groups together
is better than breaking them apart.  Together, the two efforts can feed off
each other.  Apart, they could each run down due to lack of interest.

You will know much better than any of us the details of your communities.
