U200 and Intel(R) Xeon(R) Platinum 8163 CPU. I only tried one to one, so I am not sure about TX or RX. iperf is used for the test. lspci output...

There is only one CPU, and the two servers are identical. The performance of iperf3 is worse, only 8Gbps with default settings.

What does `link partner` means? server or switch, or something else? How I can get the info of link partner?

Ok, the two FPGA cards are connected through a P4 switch. And, it seems that RX is the bottleneck. In 1to2 case, each iperf sender can get 26G. But in...

Hi, I replaced a AU200 card with Mellanox CX6 NIC, and found that when running iperf from AU200 to CX6, 16 connections achieve 75.8Gbps in total, but running iperf from...

I added a log before https://github.com/ucsdsysnet/corundum/blob/7c8abe261b2ec3e653da7bc881f769668a231bde/modules/mqnic/mqnic_rx.c#L296 to get info about `cq_ring->head_ptr` and `cq_ring->tail_ptr`. I found there are some bursts in `head-tail`, and only a few cqes are in cq ring...

yes, mutiple RX queues are used. The figure is plotted with the data where iperf has only one connection from CX6 to U200. I also tested with more connections, and...

Hi, Alex, Sometime, the one-to-one throughput can be 17Gbps, while it is 10Gbps in most time. Then I add a log to get `cq index`, `rx queue head` and `rx...

I have got it. Flow-level ecmp is based on five-tuple, so the flows that have the same hash value will have the same next hop, denoted as SW_A. If SW_A...
