<DIV><FONT face=Arial size=2>Hi Dotan,<BR> <BR>About the failure in RDMA
Read, do you mean the garbage data that's printed out?<BR>I don't mind about
that for now, that's expected because the buffer isn't initialized in the
client.<BR> <BR> <BR>I already thought about endianness of the LID,
and tried to change endianness but with no success.<BR> <BR>But now I
modified the code in both Windows and Linux to send out the LID in network
order.<BR>The Windows side does nothing(sends and receives the LID as
is).<BR>The Linunx side changes endianness of the LID before sending, and
changes endianness of the received LID.<BR>(Attached new sources and
executables)<BR> <BR> <BR>But the problem is still
there.<BR> <BR> <BR>Do you have any other
ideas?<BR> <BR> <BR>Thanks,<BR>Diego<BR></DIV></FONT>

<DIV><FONT face=Arial size=2>Hi Dotan,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I apologize for that silly mistake, obviously
WR_SEND is different from IBV_WR_SEND, and the same was for WR_RDMA_READ,
etc. etc...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, I removed <iba/ib_types.h> from the
includes, to make sure I don't use them.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now the Linux program works with send/recv
and rdma to himself (daemon/client on the same machine), but I still get the
same error when I try communication between Windows/Linux.</FONT></DIV>
<DIV><FONT face=Arial size=2>The error applies to SEND, RDMA_WRITE,
RDMA_READ, and using the daemon both on Linux or Windows.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Attached are the new sources (note that Windows
sources aren't changed).</FONT></DIV>
