<DIV><FONT face=Arial size=2>Hi Tzachi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The error is on the "daemon" side
(sender) at the polling of the cq, I get a completion work, but the status
is not success.</FONT></DIV>
<DIV><FONT face=Arial size=2>The "client" (receiver) don't sees nothing, in the
recv case none of the recv wr are used. In the rdma case, it is normal that
the recv wr isn't used.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using either send/recv and rdma operations but
the results are the same.</FONT></DIV>
<DIV><FONT face=Arial size=2>I am doing only one operation, the code is the
example in WinIB 1.3, under Mellanox\WinIB\SDK\examples\hello_world</FONT></DIV>
<DIV><FONT face=Arial size=2>with some slight modifications on Windows to get
RDMA working, and heavy modifications on Linux to use the Verbs interface
instead of ib_al.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I can send you the sources if you
want.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The same program works OK on Windows using the
same machine as client/daemon. (I don't have 2 windows machines with Infiniband
here)</FONT></DIV>

Completion with bad status: IBV_WC_RETRY_EXC_ERROR<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV><FONT face=Arial size=2>Hi</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm trying to port the source example in
Mellanox\WinIB\SDK\examples\hello_world to Linux.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The problem I have is this: after I post the
WR, I get completion with error:</FONT></DIV>
<DIV><FONT face=Arial size=2>status = 12 (IBV_WC_RETRY_EXC_ERROR) on
Linux;</FONT></DIV>
<DIV><FONT face=Arial size=2>status = IB_WCS_TIMEOUT_RETRY_ERR on
Windows.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What does this error means? I'm not sure about
it.</FONT></DIV>
<DIV><FONT face=Arial size=2>Perhaps am I sending to the wrong LID? to the
wrong QPN??</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any help is appreciated.</FONT></DIV>
