A massively parallel computer handles massive amount of data with simultaneous access requests from multiple processors, and therefore the massively parallel computer must have a large capacity secondary storage system of very high concurrency. Such a storage system should consists many disks that are connected in parallel. With such large-scale parallel disk systems, access load balancing is extremely important to enhance the effective operation of all disks. In this paper, we propose a parallel file access method named DECODE (Dynamic Express Changing Of Data Entry) which perform dynamic load balancing over all disks according to the load status of each disk. The DECODE can achieve load balancing by changing the disk for writing data to the low load disk. The efficiency of this method was verified by preliminary performance evaluation using software simulation under various access conditions by changing the access pattern and the access size. And the effects of some parameters used in this method was evaluated also.
