[ofa-general] OFED 1.2 RC2 <-> WinIB 1.3

[Kovacs Peter Tamas]

Dear all,

I've tried to do some sped tests between a Linux and a Windows box using 
InfiniBand.
I've installed OFED 1.2 RC2 to a Fedora Core 6 x64 box, and connected it 
to a Windows XP x64 box with WinIB 1.3, both machines having a Mellanox 
MHES-14XTC.
Unfortunately, ib_read_bw (which works perfectly between two linux 
boxes), fails in this case. Here is what I got:

On the linux box:
[pkovacs at localhost ~]$ ib_read_bw 1.2.3.6

Do you know why does it fail? I suspect some version incompatibilities, 
but then, who can tell which OFED goes with which WinIB?

Thanks for your kind help in advance,
Peter
