What is the Alternative?
So most existing Grande codes are written in Fortran or C with a clearly unattractive and comparatively unproductive programming environment
These current languages and tools are sufficient but does not seem likely that can build much better environments around them
- Fortran77 has excellent compilers, good user base but will not be taught broadly and clearly limited in capabilities; in particular not object oriented
- Fortran90 and HPF do not look as though they will “make it”
- Subsume discussion of C under that of C++
Five years ago, it looked as though C++ could become language of choice (perhaps with Fortran as inner core) but this appears stalled
- The language is complex and no agreement on Grande standards?
- Java halted C++ (in HPCC) ”bandwagon” even though capabilities of C++ has advanced quite significantly
