[Mpi-forum] Time To Open Source MPI

Mon Feb 3 13:36:44 CST 2020

Hi Wesley,

This change really won’t be as painful as it sounds

Then why do I have to do a bunch of unexpected/unscheduled backup and book-keeping work before an arbitrarily chosen deadline? I’m not sure that springing this surprise on folks is the wisest course of action.

Cheers,
Dan.

Because in the meantime, our testing remains broken and we don’t have another solution to fix it at the moment. We really want to have that testing fix.

This change really won’t be as painful as it sounds. There’s almost no Git commands required. No rebasing/merging/etc.

Why aren't we doing this when we finished 4.0, i.e. merged all the voted in
pull requests into the standard?

Hi folks,

** Look at the numbered list for your action items before 2020-02-18! **

Since we moved from Subversion to GitHub, there’s been a back and forth on
whether the MPI Standard Source code should be open source or closed source. As
you know (since most of you have access to it, we decided to keep the standard
closed for a few reasons (avoiding rogue copies of the Standard was a big one),
but recently, the scales have tipped back toward open sourcing and after
talking to Bill and Martin some more, we think it’s finally time to open up the
MPI Standard repository. Specifically, these are the issues that get addressed
by moving to a public repository:

* Participation to the forum has a barrier to entry (i.e. me)
* Our current automated testing system is broken and will not be fixed
* We rely on special dispensation from GitHub for free, private repositories

I’ll be discussing this in more detail in Portland, but I want to make folks
aware that this is coming now because it will have some impact on people who
are actively working on text proposals. The mitigations here should be pretty
straightforward and I have both slides (for a high level) and a wiki page (for
details) on what’s happening and what you need to do about it.

The short version for the purpose of this email and your action item leading up
the forum next week is to do two thing s:

1. Back up your branches.
2. Make a note for each of your open pull requests on where the are and what
issues they’re attached to.

Detailed notes and the slides I’ll present in Portland on how to do this are
here: [
https://github.com/mpi-forum/mpi-issues/wiki/Migrate-to-Public-Repository |
https://github.com/mpi-forum/mpi-issues/wiki/Migrate-to-Public-Repository ]

The plan is for me to flip this switch DURING THE FEBRUARY MEETING! This should
not disrupt any readings for the meeting itself as none of the pull requests
will actually be deleted, but they will all become stale and we’ll need to
re-open new ones. The main benefit of doing this during the meeting is that
if/when anyone has trouble, I’ll be there in person to provide live help to
anyone else that’s there (sorry, Marc-Andre, you’ll need to follow my slides
remotely \uD83D\uDE00).

Please email me if you have questions or concerns. If there’s enough demand, I’d
even be willing to do a short Virtual Meeting on this on Wednesday.

Thanks,
Wesley
