This comes little bit late. But if you are still looking for feedback, I would recommend "verbs;ofi_rxm". "verbs;ofi_rxd" uses UD QPs underneath and doesn't use native RDMA write operations. So is the write support in "psm3". These two are not recommended for the applications using WRITE_IMM ops. "ucx" is also a viable choice but has less feature. Also it requires the FI_MR_RAW mode so the application needs to handle that accordingly. |
