It's not a real application.
It's a performance test, demonstrating a possibilty of IB HW to send data at >
4GBps.
That's why it is using only one buffer.
That's why it doesn't care about synchronization.
But you may write a real application working almost as fast as this one.
You will have to use a pool of buffers and RC QP connection.
If the receiver side won't manage to read the data, it won't post receive WQEs,
making thereby a back pressure on the sender.

Hello Tzachi!
I have tried to use sources from latest SVN and have deal with send_bw
example. In this example I have inserted 2 bytes frame counter for receiving
control.
I found out that on receive side there is no syncronization between
write/read operations. Sending side writing frames in the shared memory
(ctx->buff) on receive side while previous frames are not read yet.
Thanks.
Zh.Sergey.

I meant openfabric stack.
As Sean mentioned, it is found under
svn://openib.tc.cornell.edu/gen1/trunk.
We provide usually only binaries, but we have the same sources
as openfabric stack, so you can look there.

Thanks but where I can get it?
In my distrib pack (MLNX_WinOF_wnet_x64_2_0_3) there is
no such dirs.
How I cat get perftests from IB source tree?

Hello!
Is there developers who wrote applications with
RDMAoIB support and can help me in such things? I need for source examples that
do send/recv with high perfomance and throughoutput on IB.
Best regards.
Zh. Sergey
