[ofw] OpenSM with HPC

[Yevgeny Kliteynik]

Hi Anatoly,

Missed Hal's response when I wrote mine.
As Hal says, Windows SM version is old. IMHO, fixing problems like
you've reported it is not even an option, because it will involve
serious changes to existing features or implementing additional ones,
which was already done in the Linux OpenSM.
So I can only reiterate what Hal has already said - OpenSM in Windows
needs to be updated to the latest and greatest.
