SnuRHAC A Runtime for Heterogeneous Accelerator Clusters with CUDA Unified Memory

Overview

SnuRHAC is an open-source framework that provides an illusion of a single GPU for multiple GPUs in a cluster. SnuRHAC automatically distributes workload and manages data across the nodes. It exploits several optimization techniques such as prefetching to maximize the performance. SnuRHAC aims to achieve both ease-of-programming and performance for GPU programming.

SnuRHAC consists of three components: a memory access pattern analyzer (MAPA), a linux kernel module (SnuRHAC-Driver), and a runtime system (SnuRHAC-Runtime).
