I may be missing your point but is there something in the Windows OpenIB/OpenFabrics license that precludes using Windows OpenIB licensed code (e.g. BSD like license) in concert with non OpenIB code (like LGPL) ? Isn't that essentially what using the Windows pthreads DLL with OpenSM would be like ? As I understand it, I don't think this requires a license change or anything in the OpenIB Windows charter prevents this or needs changing. > > > The only two ways that I see around this are 1) Change the > > license of > > > open IB windows which might be a complicated thing. 2) Find an > > > implementation of pthreads that is BSD. > > > > BTW, just wondering...

In all the cases I'm aware of, the portability is from Linux to Windows and not the other way around. -- Hal > > Sasha > > > > > > > > Thanks > > > Tzachi > > > > > > > -----Original Message----- > > > > From: Sasha Khapyorsky [mailto:[EMAIL PROTECTED] > > > > Sent: Thursday, February 08, 2007 7:46 PM > > > > To: Tzachi Dar; Yossi Leybovich > > > > Cc: Yevgeny Kliteynik; OPENIB; Michael S.
