19 Oct 2009 Optimizing Sun HPC Hardware for ANSYS FLUENT [22344]
Guidelines for IT Administrators

The Sun BluePrints article "Sun Business Ready HPC for ANSYS FLUENT: Configuration guidelines for Optimizing ANSYS FLUENT Performance" by William Aiken explores the parameters to be considered when defining a processing configuration for ANSYS FLUENT. The number of cores (independent computing elements), amount of memory, and interconnect options are discussed. For situations where a significant amount of file I/O will occur, an overview of parallel and serial file system operations and storage subsystems is also provided.

11 Aug 2009 Replacing HDDs with SSDs to Improve HPC Systems I/O Performance [22082]
Also Will Reduce Energy Usage and Cooling Load

An argument is made for the use of SSD devices in benefiting HPC applications with large I/O components in a Sun BluePrints Online article by Lawrence McIntosh in Sun's Systems Engineering Solutions Group and Dr. Michael Burke in Sun's Strategic Applications Engineering. The two compare traditional hard disk drives (HDDs) and the newer solid state drive (SSD) technology in high-performance computing (HPC) applications. Application-based benchmarking and storage performance benchmark testing are used and demonstrate significant benefits in the use of SSD devices for HPC applications with large I/O components, the authors conclude.
