EIA-9975011Princeton UniversityKai LiNext Generation Software: Adaptive, Performance-Portable Software for Next-Generation and Immersive ApplicationsA new generation of applications is becoming very important for high-performance computing, including collaborative design, interactive walkthroughs and large data visualization, and telepresence. They require tremendous resources including CPU, memory, storage, and audio/visual devices, and they have substantially different characteristics, performance goals and system interactions than traditional scientific applications. For example, they have extremely irregular and unpredictable data access needs and workload distributions, they interact more dynamically and with many more types of input/output sensors and devices, they involve dynamic user interaction and steering, and their goal is to deliver the best possible quality at a fixed output refresh rate rather than a solution of fixed quality in the minimum possible time. As computer architectures become more complex, it becomes increasingly difficult to develop such applications to achieve the desired performance. Three properties are critical: (i) high performance for rich interactive behavior, (ii) adaptability and isolation in all layers (i.e. the complexity, and unpredictability demand that each layer of application or system software must adapt to the layers above and below it-through performance modeling and through runtime feedback and adaptation-and should try to shield the neighboring layers from each other's complexity), and (iii) performance portability across component upgrades and across the different major types of platforms that may be used in such environments. Our goal is to develop the software building blocks, runtime systems and design methodologies to assist such application development.

EIA-9975011普林斯顿大学李凯下一代软件：用于下一代和沉浸式应用程序的自适应、高性能便携式软件新一代应用程序对于高性能计算变得非常重要，包括协作设计、交互式演练和大数据可视化以及网真。 它们需要大量资源，包括 CPU、内存、存储和音频/视频设备，并且与传统科学应用程序相比，它们具有截然不同的特征、性能目标和系统交互。 例如，它们具有极其不规则和不可预测的数据访问需求和工作负载分布，它们更加动态地交互并与更多类型的输入/输出传感器和设备交互，它们涉及动态用户交互和指导，它们的目标是提供尽可能好的服务固定输出刷新率下的质量，而不是在尽可能短的时间内提供固定质量的解决方案。 随着计算机体系结构变得更加复杂，开发此类应用程序以实现所需的性能变得越来越困难。 三个属性至关重要：（i）丰富交互行为的高性能，（ii）所有层的适应性和隔离性（即应用程序或系统软件的每一层必须适应其上方和下方的层的复杂性和不可预测性要求） (iii) 跨组件升级和跨可能在此类环境中使用的不同主要类型平台的性能可移植性。 我们的目标是开发软件构建块、运行时系统和设计方法来协助此类应用程序开发。
