本文描述了UNITY的愿景，UNITY是一种新的高性能计算数据存储抽象，它将整个内存层次结构（包括传统上分离的内存和基于文件的数据存储）置于一个存储连续体中。通过使用新颖的API和一组围绕智能运行时系统的服务，UNITY能够提供许多有价值和有趣的好处。统一存储空间提供了一个可扩展和弹性的数据环境，可以根据多种因素（包括所需的持久性和能源预算考虑因素）动态管理数据到可用资源的映射。通过消除高性能计算领域科学家为快速发展的数据存储技术开发依赖于架构的优化的需要，UNITY解决了易用性和性能问题。
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 memory-and 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.
