This paper describes the vision for UNITY, a new high-performance
computing focused data storage abstraction that places the entire
memory hierarchy, including both traditionally separated memoryand
file-based data storage, into one storage continuum. Through
the use of a novel API and a set of services centered around a
smart runtime system, UNITY is able to provide a number of valuable
and interesting benefits. The unified storage space provides a
scalable and resilient data environment that dynamically manages
the mapping of data onto available resources based on multiple
factors, including desired persistence and energy budget considerations.
By eliminating the need for high-performance computing
domain scientists to develop architecture-dependent optimizations
for rapidly evolving data storage technologies, UNITY addresses
both ease-of-use and performance.
