| 摘 要： | 本文介绍作者研制的一个基于任务排队动态调度并任务且具有进程迁移功能的并行计算支持环境ＤＰＶＭ系统。它是对ＰＶＭ系统的改进，以网络中各主机的ＣＰＵ利用率和ＣＰＵ队列长度为负载指标，动态调度系统中的并行任务以使整个并行任务的执行时间最短。在并行任务执行期间，ＤＰＶＭ系统使用进程先锋来进一步支持动态调度、主人优先和关机迁移的功能。

| Abstract: | The DPVM, a system based on queuing for dynamic scheduling and migrating parallel tasks, is presented in this paper. It is able to dynamically choose idle machines for executing parallel tasks, and make load balanced by migratingtasks among machines. It improves the utilization of resources and responding timeof jobs. Experiments with typical applications show that DPVM can make PVM applications run with better performance. |
