Abstract

Parallel file systems often work guided by APIs which provide hints to access storage in a coordinated manner. Nevertheless, the current APIs do not offer the expressiveness necessary to specify I/O operations conveniently in irregular applications. We characterize the state of irregular applications that precedes the performance degradation of the parallel file system and we propose a schedule based on profile information.
