摘要： 本文着重讨论并行处理领域里的多任务有关技术,讨论了并行度、多重处理和多任务处理的一般概念。在此基础上,围绕处理机分配、调度和处理机通讯,讨论了并行处理的模型,并行粒度(Gra-nularity)和并行处理开销的关系。许多并行系统通过硬件支持来减少系统开销,所以特别较全面地介绍了Convex ASAP技术。

Abstract: Multitasking technologies in the area of parallel processing are presented, including the main concepts of parallelism, multiprocessing and multitasking. A model of parallel processing and the relattion between parallel granularity and parallel processing overhead are also provided for processor allocation, scheduling and communications. Since not a few parallel systems incorporate special hardware to reduce system overhead, Convex ASAP technique is particularly introduced in detail.
