(Pl. note that I am not a full fledged Fortran programmer but I do use
it rarely!)

        (X) Automatic compiler parallelization
            Interesting area. I would like to see how this evolves hand
            in hand with the next generation of super-scalar RISC processors
            (PA-8000 for eg. appears to have some nice features which might
             help research in this area)

        (_) Compiler directives

        (X) Message-passing
            (using MPI/PVM)

        (_) High Performance Fortran (HPF) 

        (X) Threads
            Have used for parallelizing applications on KSR. and for
            improving performance of few GUI apps on AIX.

          
            
        (_) Parallel Translators (KAP, VAST, FORGE, etc.)
        (_) Others (please specify)


>Which of the following criteria were important in your choice of model
>above?

        (X) Portability
            (not in the case of  threads, due to lack of thread safe
             libraries.) Hope this changes soon.

        (X) Performance

        (X) Ease-of-programming 
            MPI, PVM.

        (_) Others (please specify)
