Intel Wins IO500 10-node Challenge with DAOS

In this video from SC19, Kelsey Prantis from Intel describes how the DAOS parallel file system won the IO500 10-node Challenge with Intel Optane DC persistent memory. As an all-new parallel file system, DAOS will be a key component of the the upcoming Aurora supercomputer coming to Argonne National Laboratory in 2021.

Intel has been building an entirely open source software ecosystem for data-centric computing, fully optimized for Intel architecture and non-volatile memory (NVM) technologies, including Intel Optane DC persistent memory and Intel Optane DC SSDs. Distributed Asynchronous Object Storage (DAOS) is the foundation of the Intel exascale storage stack. DAOS is an open source software-defined scale-out object store that provides high bandwidth, low latency, and high I/O operations per second (IOPS) storage containers to HPC applications. It enables next-generation data-centric workflows that combine simulation, data analytics, and AI.”

Unlike traditional storage stacks that were primarily designed for rotating media, DAOS is architected from the ground up to make use of new NVM technologies, and it is extremely lightweight because it operates end-to-end in user space with full operating system bypass. DAOS offers a shift away from an I/O model designed for block-based, high-latency storage to one that inherently supports fine- grained data access and unlocks the performance of next- generation storage technologies.”
