[petsc-users] Software for load balancing to improve parallel performance to be used with PETSc

[TAY wee-beng]

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!
