Multiprocessor File System Interfaces
Increasingly le systems for multiprocessors are de signed with parallel access to multiple disks to keep I O from becoming a serious bottleneck for parallel ap plications Although le system software can trans parently provide high performance access to parallel disks a new le system interface is needed to facili tate parallel access to a le from a parallel application We describe the di culties...
متن کاملEfficient Striping Techniques for Multimedia File Servers
In this paper, we describe techniques for determining the stripe unit size and the degree of striping for efficient placement of continuous media data on disk arrays. To determine the stripe unit size, we present analytical models that use the server configuration and the workload characteristics to predict the load on the most heavily loaded disk in redundant and non-redundant arrays. We use t...
متن کاملParallel file striping on optical jukebox servers
In the near future, large digital media servers are expected to offer storage capacities in the order of petabytes. Servers made of clusters of PC's connected to jukeboxes may represent an interesting alternative compared with servers made of arrays of magnetic disks. However, due to disk exchange overhead, higher seek times and lower data transfer rates, access to data located on optical disks...
متن کاملEvaluating Dynamic File Striping For Lustre
We define dynamic striping as the ability to assign different Lustre striping characteristics to contiguous segments of a file as it grows. In this paper, we evaluate the effects of dynamic striping using a watermark-based strategy where the stripe count or width is increased once a file’s size exceeds one of the chosen watermarks. To measure the performance of this strategy we used a modified ...
متن کاملA Multiprocessor Extension to the Conventional File System Interface
As the I/O needs of parallel scienti c applications increase, le systems for multiprocessors are being designed to provide applications with parallel access to multiple disks. Many parallel le systems present applications with a conventional Unix-like interface that allows the application to access multiple disks transparently. By tracing all the activity of a parallel le system in a production...
