GPM: Exploring GPUs with Persistent Memory

Series: M.Tech (Research) Thesis Defense

Speaker: Shweta Pandey

Date/Time: Sep 13 11:00:00

Location: Microsoft Teams - Online

Faculty Advisor: Arkaprava Basu

Abstract:
GPUs are a key computing platform for many application domains. While the emergence of non-volatile memory has brought the promise of fi ne-grain byte-addressable persistence (a.k.a., persistent memory, or PM) to CPU applications, the same unfortunately is beyond the reach of GPU programs.
This work takes three steps toward enabling GPU programs to directly access PM. First, we show how various existing software and hardware technologies can be put together to enable direct access to PM from within a GPU kernel. Next, we created a workload suite of 10 GPU-accelerated applications to demonstrate how GPUs can benefit from PM. We then created a GPU library to support logging, checkpointing, and primitives for native persistence to enable GPU programmers to easily leverage PM.
