Modern High Performance I/O: Leveraging Object Stores

DescriptionAs more diverse applications move to high performance computing (HPC), the I/O workload has also become more varied. The community has spent three decades improving large-scale parallel file systems, but object stores provide new approaches and novel interfaces. At the same time, traditional parallel I/O approaches and abstractions have evolved under the covers to make use of both novel object stores and classic parallel file systems. In this full-day tutorial we will explore several object storage technologies and discuss both old and new approaches to getting maximum performance from them. With a mix of lectures and hands-on exercises, attendees will learn about object storage design and usage. We will also tackle how the classic I/O software stack has evolved to make use of object stores, as well as provide attendees with the knowledge to know when file systems and object stores are the most appropriate storage approach for their applications. By the end of the day, attendees will learn a bit more about what these new storage systems are doing, as well as how to use libraries and tools to hide the details.
