In the past few days at iMechanica, there have been quite a few messages dealing with different aspects of programming, libraries and so on...
It would perhaps be timely, therefore, to ask:
Do you have any opinion about using Java in numerical analysis (NA) / FEM / CFD etc.---i.e., in computational engineering and sciences (CES)?
Do you have any experience or hard data concerning performance of Java vis-a-vis C++ or FORTRAN, esp. for large systems, or for high-performance applications? Any pointers?
