GPUnet: networking abstractions for GPU programs

https://github.com/ut-osa/gpunet

GPUnet is a native GPU networking layer that provides a reliable stream abstraction over Infiniband and high-level socket APIs to GPU programs for NVIDIA GPUs.

GPUnet enables threads or threadblocks in one GPU to communicate with threads in other GPUs or CPUs via standard and familiar socket interfaces, regardless of whether they are in the same or different machines.

GPUnet uses Peer-to-Peer DMA (via GPUDirectRDMA) to place and manage network buffers of a GPU application directly in GPU memory.
