A major challenge for future High End Computing (HEC) systems built using many-core chips is the storage system since the available memory and bandwidth per processor core is starting to decline at an alarming rate, with the rapid increase in the number of cores per chip. Data-intensive applications that require large data sets and/or high input-output bandwidth will be especially vulnerable to these trends. Historically, the storage architecture of an HEC system has been constrained to a large degree by the filesystem interfaces in the underlying Operating System (OS). The specific focus of this research is on exploring a new storage model based on write-once tree structures. This research will explore three programming models for users of the storage system, all of which can inter-operate through shared persistent data: 1) a declarative programming model in which any data structure can be directly made persistent in the storage system, with no programmer intervention, 2) a strongly-typed imperative programming model in which a type system extension will be used to enforce a separation between data structures that can be directly made persistent and those that cannot, and 3) a weakly-typed runtime interface that enables low-level C programs to access the storage system.

使用众核芯片构建的未来高端计算 (HEC) 系统的一个主要挑战是存储系统，因为每个处理器核心的可用内存和带宽开始以惊人的速度下降，而每个处理器核心的数量迅速增加。芯片。 需要大量数据集和/或高输入输出带宽的数据密集型应用程序将特别容易受到这些趋势的影响。 从历史上看，HEC 系统的存储架构在很大程度上受到底层操作系统 (OS) 中的文件系统接口的限制。 本研究的具体重点是探索一种基于一次写入树结构的新存储模型。 本研究将为存储系统的用户探索三种编程模型，所有这些模型都可以通过共享持久数据进行互操作：1）声明性编程模型，其中任何数据结构都可以直接在存储系统中持久化，无需程序员干预，2) 强类型命令式编程模型，其中类型系统扩展将用于强制区分可直接持久化的数据结构和不能直接持久化的数据结构，以及 3) 弱类型运行时接口，可实现低持久化访问存储的 C 级程序 系统。
