....I O at the level of files. The advantage of this approach is that the application programmer need not care for the basic problems of file I O since this is accomplished by the operating system, i.e. the file system. Examples of parallel file systems are Galley [10] HFS [11] HiDIOS [19] ParFiSys[4], PIOUS [12] based on PVM [ and Vesta [8] Looking at one level above the file system, we come to the second category, namely the I O libraries. In short, this method enhances existing programming languages by features dealing with file I O. Thus, the application programmers can use ....

....ION NETWORK Distributed Partition Figure 1: Generic parallel file system architecture The following sections describe the cache scheme implemented in ParFiSys and how we solve the cache coherence problem in an efficient manner for parallel file systems. 2. 1 Cache Management in ParFiSys ParFiSys [Carretero96b, Carretero96a] is a parallel and distributed file system developed at the UPM. to provide parallel I O services for parallel and distributed systems. To fully exploit all the parallel and distributed features of the I O hardware, the architecture of ParFiSys is clearly divided in two levels following the ....
