Foil 19 Introduction to Fortran90 Arrays - II

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
1 Extract sections (subarrays) of arrays as u(lb:ub:step)
  • lb is Lower Bound
  • ub is Upper Bound
  • step (defaults to 1) is step
2 masked (conditional) Array operations using WHERE .... ELSEWHERE
3 Can still do Fortran77 array element operations (DO Loops) but of course this might not be interpretable for efficient parallelism by HPF compiler
4 Note Fortran90 designed for science and engineering with originally special concern for vector supercomputers but Cray supports F77 better than F90(!)
