Seminar: Fastest Terabyte/sec Parallel File System for High-Performance Computing

The Titan supercomputer, a 27 PFLOPSCray XK7 system, has radically increased the I/O demand beyond the capabilities of the existing Spider Lustre parallel file system at the Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory (ORNL). Spider, deployed in 2008, was the fastest Lustre parallel file system in the world at the time of deployment. Spider is capable of performing at 240 GB/s at the Lustre file system level and had a capacity of 10 PB. The new Lustre parallel file system is designed to provide 32 PB capacity to OLCF users at an aggregate rate of 1 TB/s at the Lustre file system level. This presentation introduces OLCF and ORNL and describes the architecture, design choices and configuration of the next-generation Spider file system.
