Sun Grid Engine Inspect [22281]
New Monitoring Tool Developed Purely in Java, Uses JMX

Inspect is a new monitoring tool included in Sun Grid Engine (SGE) Update 3. It is a flexible interface for viewing current and historical data on SGE cluster(s) and the Service Domain Manager. The new GUI-based monitoring tool is developed purely in Java and uses JMX. This means an SGE installation has to enable JMX. Users interested in using Inspect must have version 6+ of the following software: Sun JDK, OpenJDK, IcedTea, and Apple JDK.

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.

Configuring Systems for Very High Bandwidth I/O [21964]
Enables Data-intensive Streaming Read/Write I/O Performance.

The Sun BluePrints Online paper "Configuring Systems for High Bandwidth I/O" by Kevin Colwell and Carolyn Bumatay describes a recipe for configuring systems to support the very high bandwidth I/O capabilities needed by such data-intensive applications as operational intelligence and surveillance, epidemic trend analysis and prediction, failure analysis of aircraft and ships, predictive traffic management, weather and ocean forecasting, virtual design, astronomy, human genomics, and other scientific disciplines that are data-intensive, and depend on streaming read/write I/O performance.
