Case Study: Maxwell Code Automatic Parallelization

• The Maxwell program is automatically parallelized with: f77 -apo -O3 maxwell.f

• There are 3 parallel sections:

  • Initialization
  • Calculation of H
  • Calculation of E

• There are no data dependencies in each of the lops;

• The compiler divided k-loop iterations among N processors

Iterations
