Abstract

Parallel symbolic computation has attracted considerable interest in recent years. Research groups building multiprocessors for such applications have been frustrated by the lack of data on how symbolic programs run on a parallel machine. This report describes the behavior of Multilisp programs running on a shared memory multiprocessor. Data was collected for a set of application programs on the frequency of different instructions, the type of objects accessed, and where the objects were located in the memory of the multiprocessor. The locality of data references for different multiprocessor organizations was measured. Finally, the effect of different task scheduling strategies on the locality of accesses was studied. This data is summarized here, and compared to other studies of LISP performance on uniprocessors.
LISP在多处理器上的初步研究
并行符号计算近年来引起了人们极大的兴趣。为这类应用构建多处理器的研究小组一直因缺乏符号程序如何在并行机器上运行的数据而受挫。此报告描述在共享内存多处理器上运行Multilisp程序的行为。为一组应用程序收集有关不同指令的频率、访问对象的类型以及对象在多处理器内存中的位置的数据。测量了不同多处理器组织中数据引用的局部性。最后,研究了不同任务调度策略对访问局部性的影响。这里总结了这些数据,并与其他关于单处理器上LISP性能的研究进行了比较。
