[OMPI users] UCX and multithreading

[marcin.krotkiewski]

Hi, all,

I'm reading in the changelog 3.0.0 that

- Use UCX multi-threaded API in the UCX PML. Requires UCX 1.0 or later.

Also, the changelog for 3.1.0 it says that

- UCX PML improvements: add multi-threading support.

Could anyone briefly explain, what those mean in terms of the
functionality / performance? Does this mean that the UCX PML have an
internal progress thread for asynchronous comm, or is this only related
to supporting multi-threaded MPI applications?

BTW, is there any plans to support progress threads in the future?

Thanks!
