9807112Lizy K. JohnCraig M. ChaseThe University of Texas at AustinExperimental Software Systems: Performance Impact of Contemporary Programming Paradigms and WorkloadsThe primary objective of this project is to characterize several contemporary programming paradigms, including object-oriented computing and networked computing. This study investigates why contemporary programs (developed in C++, Java, etc.) tend to run slower than traditionally developed (e.g., Fortran and C) programs. For example, when the same application is written in an object-oriented fashion and also constructed in a traditional procedural style, the object-oriented version is known to consume more memory, exhibit worse cache behavior, and to have less predictable branch behavior. This research attempts to isolate these effects and trace them to specific elements of the object oriented programming style. The principal benefit of this study is the collection of knowledge concerning how microprocessors should be designed in the future. Design decisions and engineering tradeoffs in microprocessors are often based on assumptions made about the types of programs that these processors will execute. However, detailed and accurate program characterization, such as those in this project, allows processor designers to make intelligent and informed engineering decisions.

Chasethe在Austinexpermiment Software Systems：当代编程范式和工作负载的性能影响该项目的主要目标是表征几个当代编程范式，包括对象计算和网络计算。 这项研究调查了为什么当代计划（在C ++，Java等中开发的）往往比传统开发的计划（例如Fortran和C）程序慢得多。 例如，当以对象为导向的方式编写相同的应用程序并以传统的程序样式构建时，已知该版本会消耗更多的内存，表现出更差的缓存行为，并且具有较低的可预测分支行为。 这项研究试图隔离这些效果，并将其追溯到面向对象的编程样式的特定元素。 这项研究的主要好处是收集有关将来应如何设计微处理器的知识。 微处理器中的设计决策和工程折衷通常基于对这些处理器将执行的程序类型的假设。 但是，详细且准确的程序表征（例如该项目中的计划）使加工设计师可以做出智能和知情的工程决策。
