High-performance Java codes for computational fluid dynamics
The computational science community is reluctant to write largescale computationally-intensive applications in Java due to concerns over Java’s poor performance, despite the claimed software engineering advantages of its object-oriented features. Naive Java implementations of numerical algorithms can perform poorly compared to corresponding Fortran or C implementations. To achieve high performance, Java applications must be designed with good performance as a primary goal. This paper presents the objectoriented design and implementation of two real-world applications from the field of Computational Fluid Dynamics (CFD): a finitevolume fluid flow solver (LAURA, from NASA Langley Research Center), and an unstructured mesh adaptation algorithm (2D TAG, from NASA Ames Research Center). This work builds on our previous experience with the design of high-performance numerical libraries in Java. We examine the performance of the applications using the currently available Java infrastru...
