Workshop: Metall: A Persistent Memory Allocator Enabling Graph Processing
DescriptionWe present Metall, a persistent memory allocator designed to provide developers with an API to allocate custom C++ data structures in both block-storage and byte-addressable persistent memories (e.g., NVMe and Intel Optane DC Persistent Memory). Metall incorporates state-of-the-art allocation algorithms in Supermalloc with the rich C++ interface developed by Boost.Interprocess, and provides persistent memory snapshotting (versioning) capabilities. We demonstrate Metall processing large graphs in a variety of conditions and data-structure configurations, indicating a bright future for data-analytics leveraging emerging persistent memory technologies.
