HUM Hidden Unified Memory

Overview

HUM (Hidden Unified Memory) is an open-source framework for NVIDIA GPUs that hides host-to-device memory copy time without any code modification. It overlaps the host-to-device memory copy with host computation or CUDA kernel computation by exploiting CUDA Unified Memory and fault mechanisms.

HUM consists of two components: a linux kernel module (HUM-driver), and a runtime system (HUM-runtime).
