Optimizing MPI Communication on Multi-GPU Systems Using CUDA Inter-Process Communication

Many modern clusters are being equipped with multiple GPUs per node to achieve better compute density and power efficiency. However, moving data in/out of GPUs continues to remain a major performance bottleneck. With CUDA 4.1, NVIDIA has introduced Inter-Process Communication (IPC) to address data m...
