Rescheduling Optimal Algorithm Based on CPU Factor

In the stage of spacecraft model design, the use of expensive licensed resources is extremely tight, the calculation efficiency is low. This study analyzed the shortcomings of the existing job dispatching mechanism in the high performance computing system that without considering the idle state of the high performance host. Based on the platform LSF, combined with the characteristics of spacecraft simulation analysis, a new resolution, i.e., rescheduling algorithm based on high CPU factor, which is used to distinguish the relative running speed of different machines, priority has been designed and implemented. The simulation results show that the algorithm can effectively improve the efficiency of the operation and shorten the occupancy time of licensed resources. The practical case shows that the algorithm has the possibility of popularization and application, which can improve the utilization of licensed resources and meet the needs of cost control for spacecraft simulation analysis and the efficacial utilization of resources.
