摘要
该系统以CRAY X-MP4机系统为体系结构,利用单机COS 操作系统,探讨了一种无逻辑CPU方式的多处理机调度策略。并着重研究了多任务库所支持的TSKSTART语句的执行流程,以及它在OS中的实现。
In Cray X-MP/4 there is the logical CPU which connects task to physical CPU. The management overhead of logical CPU is very high. This paper proposes a CPU schedule scheme without logical CPU, and describes its implementation. By comparison this overhead is really lower. Research on the execution of statement TSKSTART supported by multitasking library is based on the COS (Cray Operating System).
