Parallel functional disk array for high performance computing

In high performance scientific computing, operations such as searching, sorting, filtering are very frequent. Due to limited access ability of storage system and limited capacity of main memory, it is difficult to archive high performance of data access using traditional methods, and it is also impossible to carry all the data into main memory and operate in the memory. A new kind of storage system architecture, called Parallel Functional Disk Array (PFDA), is proposed in this paper. The study of the PFDA in this paper is mainly focused on the following two aspects: one is the architecture study of PFDA, including the storage requirement of high performance scientific computing environment and the operation frequency for different function, the other is the algorithm of dynamic analysis and scheduling of function units to perform in parallel, so as to solve the conflict problem among function units and the data dependent problem caused by the data distribution in the redundant disk array
