Cast Elimination for Containers in Java

August 4, 2008

Report from Presenter

We proposed optimization techniques for Java at the third international workshop on Implementation, Compilation, Optimization of Object-Oriented Languages, Programs and Systems (ICOOOLPS 2008). This workshop was held at Paphos, Cyprus on July 7th, 2008, and the attendees discussed a wide range of topics about the implementation techniques for object-oriented languages, such as optimization and garbage collection.

Our proposal, entitled "Cast Elimination for Containers in Java", eliminates type casts for standard library container elements and improves the performance of Java applications that heavily use containers. For example, our optimization techniques improve SPECjbb2005 performance by 14.8%. SPECjbb2005 is one of server-side Java benchmarks.
