Configuration Example
First, get the source code by cloning the git repository (you want to work with version 4.0):
...
On successful completion you will have an executable called xcompact3d.
Running the Taylor-Green vortex case
...
When p_row and p_col are set to zero, the size of the pencils will be automatically decided during the execution. The simulations are performed with [p_row x p_col] MPI_processes (with one MPI_process per core). For instance, if you want to use 128 cores/MPI_processes, you can have p_row x p_col = 2 x 64, 4 x 32, 8 x 16, 16 x 8, 32 x 4, 62 x 2 (p_row and p_col should be equal or larger than 2). For the competition, it is advised to try difference values for best performance.
