Abstract :
The authors describe a reference implementation and evaluation of Scalable I/O Low-Level API (SIO-LLAPI) on a scalable file system (COSMOS) of the Dawning2000 cluster system. This prototype provides scalable I/O API, keeps COSMOS compatible file structure and stripping algorithm, and runs as a user-level library. We present the initial experiences and evaluation results. It is observed that SIO-LLAPl provides the opportunities of significant I/O performance improvement on a cluster system.
