WebMar 2, 2015 · 1 Answer. RDMA atomic operations are implemented using PCI-express read and write operations. As such they do not provide atomicity with respect to the CPU's atomic operations, nor with respect to other HCAs. Are there HCAs (say, Mellanox's ConnectX-4) that use PCIe atomics instead of read + write over PCIe? WebIn order to perform RDMA operations, establishment of a connection to the remote host, as well as appropriate permissions need to be set up first. The mechanism for accomplishing this is the Queue Pair (QP). For those familiar with a standard IP stack, a QP is roughly equivalent to a socket. The QP needs to be initialized on both sides of the ...
