Have you tried Mellanox Infiniband and RDMA?
- geerlingguy 6y agoCheck out the linked GitHub repo: https://github.com/geerlingguy/raspberry-pi-pcie-devices https://github.com/geerlingguy/raspberry-pi-pcie-devices — for any card I'm actually testing, I have an open issue. For proposals or discussions around a certain topic, there are some ongoing conversations in the Discussions tab. Specifically concerning Infiniband, check out this issue: https://github.com/geerlingguy/raspberry-pi-pcie-devices/discussions/12 https://github.com/geerlingguy/raspberry-pi-pcie-devices/dis... - I'd be willing to test, but currently I have a bit of a backlog of other gear I'm getting through testing :)
- Namidairo 6y agoWouldn't you saturate the bus fairly easily with a Mellanox card? I can't imagine the experience would be optimal.
- geerlingguy 6y agoFrom all my testing, it looks like the maximum throughput you can get on the entire PCIe x1 gen 2 lane on the CM4 is about 3.2-3.4 Gbps. But that's still better than the current maximum of 1 Gbps over Ethernet, or the ~3 Gbps I have tested through a USB 3.0 card.
