UVMBench: A Comprehensive Benchmark Suite for Researching Unified Virtual Memory in GPUs

20 Jul 2020 Yongbin Gu Wenxuan Wu Yunfan Li Lizhong Chen

The recent introduction of Unified Virtual Memory (UVM) in GPUs offers a new programming model that allows GPUs and CPUs to share the same virtual memory space, shifts the complex memory management from programmers to GPU driver/ hardware, and enables kernel execution even when memory is oversubscribed. Meanwhile, UVM may also incur considerable performance overhead due to the tracking and data migration along with the special handling of page faults and page table walk... (read more)
