市场经济与高等教育

市场经济体制的逐步建立，使高等教育既面临机遇，又面临挑战。教育与经济是互动关系．经济是教育的物质基础，教育要适应经济发展的需要。高等教育作为一种社会活动．要与经济、政治、文化相互联系、相互作用。与此同时，高等教育内部在各种社会因素的制约下．按照教育自身的规律运行。

A Dynamic Job Scheduling Algorithm for Parallel System

One of the fundamental problems in parallel and distributed systems is deciding how to allocate jobs to processors. The goals of job scheduling in a parallel environment are to minimize the parallel execution time of a job and try to balance the user‘s desire with the system‘s desire. The users always want their jobs be completed as quickly as possible, while the system wants to service as many jobs as possible. In this paper, a dynamic job-scheduling algorithm was introduced. This algorithm tries to utilize the information of a practical system to allo-cate the jobs more evenly. The communication time between the processor and scheduler is overlapped with the computation time of the processor. So the communication overhead can he little. The principle of scheduling the job is based on the desirability of each processor. The scheduler would not allocate a new job to a processor that is already fully utilized. The execution efficiency of the system will he increased. This algorithm also can he reused in other complex algorithms.
