网络并行计算环境中的任务派生机制和进程调度策略

TASKS FORKING MECHANISM AND PROCESS SCHEDULING STRATEGY IN A NETWORK PARALLEL COMPUTING ENVIRONMENT

在多用户的网络环境中，并行计算任务的分配和网络负载的动态变化都会影响并行计算任务的响应时间和执行效率．文中通过在ＰＶＭ中增加负载平衡策略，以及对操作系统的调度策略进行修改，使得并行计算任务的分配更合理，并且降低了网络串行负载变化对其运行的影响．

In a multi user network environment, the response time and running efficiency of parallel applications can be influenced by the distribution of parallel tasks and the varying work load in the network. By adding load balancing strategy to PVM and by modifying the process scheduling strategy, the tasks of parallel job can be distributed more reasonably, and its running speed can be less influenced by the variation of serial work load.
