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.

10 Aug 2009 Best Practices for Performance Tuning MD Nastran [22068]
Sun BluePrints Provides Overview for Running MD Nastran in HPC Environment

Get performance tuning recommendations and best practice guidelines on MSC.SoftwareÂ’s HPC application, MD Nastran, and the hardware platform in a Sun BluePrints piece that aims to educate its readers on

  • estimating the optimum amount of memory (RAM) needed to run a particular MD Nastran analysis,
  • determining the number of concurrent MD Nastran jobs that can efficiently run on one compute node and
  • maximizing MD Nastran's File Management System (FMS) interface to access the available storage devices for optimum I/O performance.

The 39-page PDF is written for experienced MD Nastran users who are interested in performance-related issues.
