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.

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 got the same issue like this: #5.

my card is mlx5 with roce mode:
CA 'mlx5_0'

Hardware version: 0
Node GUID: 0x0c42a103007555a4
System image GUID: 0x0c42a103007555a4
Port 1:

Physical state: LinkUp

Base lid: 0
LMC: 0
SM lid: 0
Capability mask: 0x00010000
Port GUID: 0x0e42a1fffe7555a4

Thanks!

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.

Hello,

My Mellanox installation has GID information, how do I use it in your code? Thank you1

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 ?
