Challenges to Future Use of Java for Automotive Large-Scale Simulations 2000-01-1376

Java is a very popular programming language for Internet- based applications. With the increasing use of webbased technology in the automotive industry, Java has the potential to play a significant role in the future of large-scale 3-D computations such as crash analysis and aerodynamic modeling. This paper focuses on Java' s current bottlenecks for such applications and activities to overcome those limitations. Topics discussed include: current status of large-scale automotive computations; numeric performance comparisons of Java, C++, and FORTRAN; Java benchmarks to assess numerical performance; Java' s current floating-point limitations; a roadmap for Java evolution amongst the commercial automotive independent software vendors (ISVs).
