Session Presented at 5th IndicThreads.com Conference On Java held on 10-11 December 2010 in Pune, India
Rising power dissipation in microprocessor chips is leading to a trend towards increasing the number of cores on a chip (multi-core processors) rather than increasing clock frequency as the primary basis for increasing system performance. Consequently the number of threads in commodity hardware has also exploded. This leads to complexity in designing and configuring high performance Java applications that make effective use of new hardware. In this talk we provide a summary of the changes happening in the multi-core world and subsequently discuss about some of the JVM features which exploit the multi-core capabilities of the underlying hardware. We also explain techniques to analyze and optimize your application for highly concurrent systems. Key topics include an overview of Java Virtual Machine features & configuration, ways to correctly leverage java.util.concurrent package to achieve enhanced parallelism for applications in a multi-core environment, operating system issues, virtualization, Java code optimizations and useful profiling tools and techniques.
Takeaways for the Audience
Attendees will leave with a better understanding of the new multi-core world, understanding of Java Virtual Machine features which exploit mulit-core and the techniques they can apply to ensure their Java applications run well in mulit-core environment.
