Hi, I'm running a 3D Fortran CFD code. The grid used is Cartesian. The current code is partitioned in the z direction for MPI.
For e.g. for total size z = 10, if partitioned into 5 cpus, it'll become size z = 2 for each cpu. Uneven grids are used to reduce the number of grids and the main bulk of grids clusters around the center. I read about load balancing software. I wonder if it will improve the performance/speed of my code. If so, what are the available choices for use with PETSc and Fortran? Are ParMETIS, Zoltan or Isorropi recommended? Thanks! -- Yours sincerely, TAY wee-beng
