Cache performance of vector processors
An instruction-level simulator for IBM 3090 with VF (vector facility) has been developed for studying the performance of vector processors and their memory hierarchies. Results of a study of the locality of several large scientific applications are presented. The cache miss ratios of vectorized applications are found to be almost equal to those of their original scalar executions. Moreover, both the spatial and temporal locality of these applications (in scalar and vector executions) are strong enough to show a sufficiently high hit ratio on conventional cache structures.<<ETX>>
Directed against the principle of count by time-sharing and based on the parameter model of electrolytic zinc process,an optimization model of power supply for electrolytic zinc is established in this paper.Particle swarm optimization algorithm is applied in time-sharing power supply optimal dispatching system,obtaining optimal time-sharing power supply scheme to production.Results show that this system can effectively decrease the power consumption and create great economic profits.
