An app can register multiple memory regions. Just call register mr for each region that you want to register. > Client writes on different MRs with only one send WR. Is that possible? No - an RDMA write targets a single remote MR. > The goal is: build an array of addresses (MRs) and write (or read) with > a First Input Fist Output (FIFO) model using RDMA. > > Any ideas? If you have an array of addresses, you can register each address and store the mr handle with each. The address, rkey associations must be transferred to the remote peer, so it can issue the RDMA operations. Unless the addresses are scattered, you could also look at registering a single, larger memory region, with each RDMA operation targeting only a portion of that region. Although, based on this brief description of having a FIFO, posted receive buffers may work just as well for you. And a receive would allow incoming data to be scattered to different memory buffers. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
