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? WebRDMA allows servers, through special NICs, to access the memory of other servers without the use of the operating system, offering very high throughput, low latency networking for …

My question is: … WebRemote direct memory access (RDMA) operations require the pinning of physical memory. As a consequence, the kernel is not allowed to write memory into the swap space. If a user pins too much memory, the system can run out of memory, and the kernel terminates processes to free up more memory. Therefore, memory pinning is a privileged operation.
