Performance of open-nic-dpdk #2

Open aneesullah opened 2 years ago

aneesullah commented 2 years ago

Hi, How to reproduce the results reported in "Xilinx Answer 71453 QDMA Performance Report" with PKTGEN, only getting 10Gbps link speed on threadripper pro with U280 card. Are these results only for the QDMA example design or they apply to Open NIC also? Regards, Anees

Hi @aneesullah,

Can you say more about your test setup?

The QDMA Performance report was characterized separately by a different team and not using OpenNIC, however, performance should be similar based on using the QDMA.

The performance using pktgen-dpdk should be something along the lines of the following, however, depending on machine capabilities:

It seems from pktgen output that only 64 bytes packets are generated. How to generated larger size packets? Regards, Anees

cneely-amd commented 2 years ago

Hi @aneesullah in your testing with pktgen-dpdk, can you try something like the following:

range 0 size 64 64 1518 3
range 1 size 1500 64 1518 5
enable 0-1 range
start 0-1
cneely-amd commented 2 years ago

@aneesullah Also, maybe to go along with my above suggestion for how to vary the packet size in pktgen-dpdk, I wanted to mention that in my testing I've been enabling serdes loopback instead of a cable for those quick tests by writing 0x1 to 0x8090 (for port 0) and 0x1 to 0xC090 (for port 1).

aneesullah commented 2 years ago

Hi @cneely-amd , Thanks a lot. Improved, getting around 70 Gbps for Cable loopback but still not able to hit the link rate. Here is the PKTGEN snapshot: pktgen_cable_lp Also getting around 70 Gbps with SERDES loopback, For enabling SERDES Loopback used the following open_nic_registers_setup Any idea?

Regards, Anees

aneesullah commented 2 years ago

Another related question: pktgen-dpdk allows only 16 bytes of user fill pattern for testing, what if we have a large amount of data from a file or from memory to transfer? I think, it is not supported. What about dma_to_device and dma_from_device functions from the QDMA driver library, Can they be used to transmit custom user data at 100 Gbps with Open NIC? Shall we need to write our own dpdk app based on QDMA driver library which is patched for OpenNIC? Any suggestion how such functionality can be quickly achieved? Note, we do need to measure the performance while doing the TX/RX when transferring our data. Thanks a lot

@aneesullah I'm not sure what the best approach would be to improving the performance. I can give two examples of different machine configurations that I have tried recently. Both are using -n 4 with mapping cores like in the example.

I also have a Ryzen 5950 with 32GB for testing, but right now my GPU is using up most of the lanes and I need to swap the order of my PCI cards around before I can test it. I'll try to do that as an experiment when I get a chance.

Best regards, --Chris

Hi @aneesullah,

I tried my Ryzen 5950X machine and I'm getting the following:

Hi @cneely-amd, I checked on another machine, on this one, NUMA nodes are not enabled from the BIOS. I am able to get 100Gbps. image (5) Thanks for your help. Any idea why the enabling NUMA reduces the speed on the other machine or is it something else? Regards, Anees

cneely-amd commented 2 years ago

Hi @aneesullah, I would guess that it might have to do with NUMA and allocation of hugepages and their locality to whichever processor cores are specified in the test, but that is just a guess. --Chris

attdone commented 10 months ago

Hi @aneesullah and @cneely-amd , I am utilizing the Alveo U200 and have conducted tests with pktgen. However, the observed packet transfer rates are at 300 MBits/s for transmission and 9000 MBits/s for reception. I'm seeking guidance on how to enhance the throughput to achieve the optimal 100 Gbps. I have configured the BIOS settings in accordance with the specifications outlined on the Open-NIC DPDK Git page. image

During packet transfer, I used to get "Timeout on request to dma internal csr register", "Packet length mismatch error" and "Detected Fatal length mismatch". This hinders further transfer. Please let me know how to resolve this? image

Thanking in advance.
