DescriptionThis paper introduces PapyrusKV: a parallel embedded
key-value store for a distributed HPC architectures that
have nonvolatile memory (NVM). PapyrusKV stores keys and
values in arbitrary byte arrays across multiple NVMs in
a distribute system. PapyrusKV provides a set of
standard key-value store operations such as put, get,
and delete, and more advanced features specialized for
HPC such as dynamic consistency configuration, database
protection, zero-copy workflow, and asynchronous
checkpoint/restart. Beyond filesystems, PapyrusKV
provides HPC programmers a high-level interface to
exploit massive pools of NVM in the system, and it
organizes data to achieve high performance. Also, it
allows HPC programmers to configure PapyrusKV to meet
their application-specific requirements and/or needs. We
evaluate PapyrusKV on three HPC systems, including
OLCF's Summitdev, TACC's Stampede, and NERSC's Cori,
using real NVM devices. Our results show that PapyrusKV
can offer high performance, scalability, portability
across various distributed NVM architectures, and
usability for HPC.
