In this paper, we propose a parallel I/O system utilizing parallel commodity network attached to multiple I/O processors of parallel processing systems. I/O requests from user application are automatically distributed to parallel I/O channels to achieve the best utilization of parallel network, and the system provides highly scalable performance according to the number of channels. We also provides an API for easy user-level programming and a set of utilities for high-speed data transfer and real-time parallelized visualization based on it.
