... * Benchmark testing of storage performance using the Lustre™ parallel file system and the popular IOZone benchmark application was performed, in order to evaluate large sequential I/O operations typical for the Lustre file system employed as a compute cluster data cache. These tests were performed using three system configurations:
** A baseline test using the Lustre file system with a single HDD-based Object Storage Server (OSS)
** A Lustre file system configuration using a single SSD-based OSS similar to the baseline test
** A comparison test using the Lustre file system and two SSD-based OSSs in parallel
The results of these tests demonstrate the potential for significant benefits in the use of SSD devices for HPC applications with large I/O components.
The results of these tests demonstrate the potential for significant benefits in the use of SSD devices for HPC applications with large I/O components.

Larry McIntosh is a Principal Systems Engineer at Sun Microsystems and works within Sun's Systems Engineering Solutions Group. He is responsible for designing and implementing high performance computing technologies at Sun's largest customers. Larry has 35 years of experience in the computer, communications, and storage industries and has been a software developer and consultant in the commercial, government, education and research sectors as well as a computer science college professor. Larry's recent work has included the deployment of the Ranger system servicing the National Science Foundation and Researchers at the Texas Advanced Computer Center (TACC) in Austin, Texas.
Michael Burke obtained his Ph.D. from Stanford University. Since then he has spent over 35 years in the development and application of MCAE software. He was the principal developer of the MARC code now owned by MSC/Nastran. Following the SS Challenger disaster he developed FANTASTIC (Failure Analysis Thermal and Structural Integrated Code) for NASA and its suppliers/contractors for the analysis of rocket (nozzles) More recently he has been involved with the benchmarking of state of the art HPC platforms using the more prominent commercial ISV MCAE/CFD/CRASH and other scientific applications He has performed this benchmarking for Fujitsu and Hewlett Packard, and is currently in the Strategic Applications Engineering group at Sun Microsystems.
