	Hi Tzachi,
	 
	I attached the sources, as you requested. Please tell me if they
are stripped out by mail spam filters.
	 
	The Linux code is full of "#ifdef WIN32", treat them as "#if 0"
since that code is never meant to be compiled on Windows. I leave that
here to have some reference to what I should do.

windows)

			Hi Tzachi,
			 
			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.
			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.
			 
			I am using either send/recv and rdma operations
but the results are the same.
			I am doing only one operation, the code is the
example in WinIB 1.3, under Mellanox\WinIB\SDK\examples\hello_world
			with some slight modifications on Windows to get
RDMA working, and heavy modifications on Linux to use the Verbs
interface instead of ib_al.
			 
			I can send you the sources if you want.
			 
			 
			The same program works OK on Windows using the
same machine as client/daemon. (I don't have 2 windows machines with
Infiniband here)

				Hi Diego,
				 
				Can you give us more information on
where the error is?
				 
				Does your problem happen on the first
packet that you send or only after some time?
				Are you using send/recv or RDMA
operations?
				 
				Thanks
				Tzachi

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