[ofw] WinOF interoperable with Linux OpenIB

[Davis, Arlin R]

We could possibly resurrect the openib_scm provider without too much
effort. It was developed before the existence of rdma_cm and uses
sockets to exchange QP information.

As far as I know, the RDMA CM protocol, which is used by the Linux DAPL,
is not implemented for Windows.

 

You may be able to link the systems by going directly to the IB CM and
verbs, or using verbs and exchanging QP information over sockets.

We would like to link a Windows machine to a Linux machine with
InfiniBand and use DAPL.  IPoIB is not fast enough.   On the Linux side
we have OFED 1.2 with RHEL 5.1.    I am new to OpenIB but I hear that
Windows would have a problem with RDMA cm.   Can anyone give me some
high level advice before I get the hardware?   The Windows machine will
be Windows 2003 R2 with Mellonox SDR card. 

Thank you.
