Re: [OMPI devel] THREAD_MULTIPLE

[George Bosilca]

There is a priority change for us. It's definitively time to have a fully supported MPI_THREAD_MULTIPLE mode in Open MPI. I'm working to figure out how and where to get the cycles for this. I expect to start working on it in January. So, the good news is that 1.3 will have thread support.

  Thanks,

I seriously doubt that we're going to advance the state of threading
on the 1.2 series (which is nowhere as close as it is on the 1.3
series).

And 1.3 I think still has a way to go to before one could really say it

supports THREAD_MULTIPLE.

Here's a proposal: why don't we disable it (at least in the 1.2
