| Abstract: |
| Based on the scalability on NOWs (networks of workstations), this paper proposes an adaptive migration and coscheduling model DASIC(dynamic adaptive scalable process migration and coscheduling). DASIC takes not only coscheduling to schedule in teractive processes simultaneously, but also adaptive migrating to satisfy the system s dy namics and scalability. It can grow, shrink and load balance to adjust the processes scheduling status in the process space, and the processor pool can be expanded or shrinked. |
| Key words: Adaptive coscheduling load balancing migration scalable |
