The problem that you describes is pretty basic and even an RC shouldn't have
this issue.
Agreed!
I think that you should upgrade the HCA's Firmware. as Ronni suggested.
But I'm not sure about the fw version. As I mentioned, on that
Mellanox page the latest firwmare for the IBM version is 2.3.00 which
is the one I have. Or am I wrong?
I checked Mellanox's site and i here is the URL for the FW of ConnectX:
http://www.mellanox.com/support/firmware_table_ConnectXIB.php
In this page, i can see that the FW version is 2.5.000.
I have a feeling that the problem is in your code:
You should access the buffer that the HCA read/write as volatile, to "tip"
the compiler
that this memory will be modified by other components and he shouldn't do
any optimization
when you want to read data from it and actually do the reading ...
I tried that as you said before but didn't help.
And the RDMA read works fine.
Of course, it is possible that the problem is with my code. In fact it
looks every time closer to this possibility. But can the code be in
such a way wrong that it works on x86 but not on ppc. That is what
intrigues me.
Pay attension that the changes from PPC64 to x86 is not only the pointer
size (64 vs. 32) and the
endianess issue. It is a different CPU architecture which may cause to
many differences.
If you wish, i can review your code that handles IB offline...
