Description
In HPC, low latency communication between remote processes is crucial to application performance. InfiniBand networks can reduce the latency but require special and costly network interface cards, which are loosely coupled with CPU, thus needing to constantly re-pin pages. In this work we leverage the SMMU available in the Zynq Ultrascale+ MPSoC’s in order to perform user-level initiated zero-copy transfers in a cluster of 64-bit ARM-based nodes, achieving a 5x latency improvement over kernel-based solutions.
