Foil 59 What about other languages ?

From HPCC Software Technologies Fall 96 -- Overview and HPF Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 26 September 96. by Geoffrey C. Fox
Parallelism is a feature of problems
It can be expressed in different languages with trade-offs in performance, flexibility and convenience
Fortran 77 Þ HPF
Fortran 90 Þ HPF
C++ Þ HPC++
  • Limitations (focus) of Fortran allow higher performance implementations
HPC++ more naturally handles complex data structures e.g. data parallel collections which are not the staple array data structure of Fortran
Must have common runtime support
  • Explored by PCRC - Parallel Compiler Runtime Consortium
