To express data parallelism and so hide machine dependent features of parallel programming from the user
|
We use Fortran90 as base language both because it is
-
more advanced than Fortran 77 with object oriented features and
-
The array syntax allows an elegant explictly parallel expression of some operations
|
Use of Fortran90 is a Problem because
-
It is a complex language which it is difficult to build compilers for
-
Not many people use Fortran90 and maybe they will all switch to Java before Fortran90 gets in common practice
-
So perhaps it is "too little too late" and we should focus on supporting the past (Fortran77) and the "correct" future ( (HP)Java) and not an irrelevant middle solution .....
