High Performance Java for Scientific
and Technical Computing

Among the many features of Java as program development platform, one of the most commonly 
cited shortcomings is its performance, particularly for computational-intensive codes.  In this 
presentation we take a close look at how Java works and how it can be made to execute faster for 
scientific simulations and modeling.  We will examine optimization strategies and bytecode 
transformations that generate 100% Pure Java with 2-10x performance improvement, with speeds 
competitive with optimized C/C++ and Fortran.  We will also look at ongoing research in 
compiler technology and distributed computing that allow Java applications to reach 
supercomputing status.  Finally, we will discuss activities of the Java Numerics Group, an 
industry-wide consortium focusing on the development high performance tools, compilers, and 
libraries for high-end Java applications.
