Hi @vinawara , Can you say more about the version of Vivado that was used to build the open-nic-shell? I've been seeing an issue recently that Vivado 2022.1 seems to work, but I've been observing issues with Vivado 2022.2 and potentially 2023.1. Best regards, |

It depends on the capabilities of your machines, and iperf3 is single threaded. Typically for me, a single iperf3 will get ~14 Gbps or so, and multiple cores need to be used for sending and receiving at higher throughput. For example, I have two 16 core machines that I use for testing, and I run iperf3 like the following (running N=15 instances, binding each iperf3 instance to a processor core):

Hello team,
I'm currently testing OpenNIC shell and it's device driver with Alveo U55N/C. As mentioned in topic, the system hang after sending a kind of bursty packets. Here's the details of the issue.
Test configuration
[HOST A [U55N/C]]<----[100G Optic]---->[[U55N/C] HOST B]
both hosts have almost identical hardware and software configurations.
Sending a somewhat small-sized at a low rate works without any issues. However, when attempting to send a large-sized packet(e.g. 6000 bytes, which is fragmented into 1500-byte packets), the sender hangs. Desptie pressing 'Magic SysRq key', there is no oops or panic message on the console and the system appears to be frozen. Where should I begin troubleshooting this case?
Regards,
Jeff
