Abstract
In recent year, the speed of CPU becomes more and more progressive. However, the development of the storage system is incompetent to catch up with that of CPU. For this reason, the parallel file system is widely used to overcome this problem. In addition, as the PC cluster has increased in popularity as a parallel computing platform, the demand for system software support is necessary for parallel computing to continue to grow on this famous platform. But it may be devoid of parallel I/O systems. The parallel file system is required for providing a high performance parallel I/O system for PC clusters. Although it is so applicable to solve the bottleneck due to poor I/O performance, most of the existing parallel file systems are based on UNIX-like operating systems. Therefore, we implement a Windows based parallel file system by using Microsoft .NET framework. Design and implementation of our system are described in this thesis and the performance evaluation is performed as well. Both write and read performance are better than those of only using a single disk. The results indicate that the write performance can achieve 110 MB/s at the utmost and the read performance can also reach a peak of 75 MB/s.We develop a simple VOD system by using Microsoft DirectShow and some primary methods of MPI-IO on top of our parallel file system. These two implementations are discussed in the thesis, too. Taking advantage of the parallel file system, the VOD system could have sufficient ability to supply higher QoS for clients and the performance of MPI-IO also benefits from it and attains outstanding results without suffering serious overhead.
