Hello,
My Mellanox installation has GID information, how do I use it in your code? Thank you1
When I run the same example code on both two linux machines, it hangs in the following situation:
on client side:
Connecting to remote node
Creating buffers
Reading content from remote buffer
on server side:
Creating buffers to read from and write to
Creating buffers to receive a message
Setting up connection (blocking)
Waiting for message (blocking)
Currently I'm not sure if there is any thing I should modify for my system. What I modify is the server ip and keep the same port number as 8011.
Also, in this example code, what can I send customized data form client to server? thanks.
Hi,
When I run send-performance program on two RDMA-connected Ubuntu machines, I get the "Segmentation fault" error.
I tried running rping on the machines and it worked. However, read-write-send and send-performance programs outputs "Segmentation fault" error.
Could you please inform me why this happens and recommend ways to solve this issue?
Best regards.
I was looking at some of the asserts in side of QueuePair.cpp, and there a few that don't make much sense to me, because they repeatedly mention scatter gather but look like they're really size checks.

When a Context is created, ibv_get_device_list is called, but ibv_free_device_list is never called. This creates a small memory leak.
is there no wrapper for the call ibv_post_recv
function ?
