...don't know if this is the case with ELEMENTAL, however these functions will be called a lot of times, so it's not a good idea if they are slow. The code will run on parallel vectorial supercomputers. According to these informations, what would you suggest me to do? Try it both ways with a test program, and tell us which is better on the machine(s) and compiler(s...

...problems. It is not mere parallelism, it is a way of using/dealing with concurrency (a form of parallelism). Real world example (about "parallelism", not CSP): geometrical application, vectorial data, transforming "spaghettis" into topologically correct data (connected edges). I had debugged an existing program. It was finally giving an acceptable result, but it was not scalable. The ...
