[OMPI users] what is "thread support: progress" ?

[Riccardo Murri]

Hello,

I just re-compiled OMPI, and noticed this in the
"ompi_info --all" output:

                Open MPI: 1.4.3a1r23323
                ...
          Thread support: posix (mpi: yes, progress: no)
                ...

what is this "progress thread support"?  Is it the "asynchronous
progress ... in the TCP point-to-point device" that the FAQ
mentions?  I could not find any ./configure option to enable or
disable it.

Cheers,
Riccardo
