Scalability and I/O efficiency are two of the biggest challenges in building cloud storage system, especially to the data-intensive applications that will run on cloud. To cloud computing, constructing a suitable architecture for every kind of cloud service is the key to succeed. But very little work has been done to create a valid and standard cloud storage architecture. In this paper, a four-layer...
It can achieve a very good teaching effect by the combination of software engineering theory course and practice course. This paper presents the design and implementation steps of a software engineering practice course. It also describes the requests of which students should submit materials in the implementation stage, lists the knowledge areas and the students outcomes according to The Guidelines...
One way of improving I/O performance is to carry out I/O operations in parallel, which is supported by parallel file systems. The data management techniques are very important to build a parallel file system with high performance and high reliability. A simple and efficient parallel file data management method was implemented. A fixed stripe size and redundant data placement technique was used. Experimental...
One important way of solving I/O bottleneck is to develop parallel file system. Research showed that the strided file access pattern in scientific applications combined with current file system methods to perform these accesses lead to unacceptable performance for large data access. To enhance performance of discontiguous data access, we have created a new high performance I/O method: the user-defined...
