This page is an overview, configuration and tasks for ISC22 Student Cluster Competition teams.
...
On successful completion you will have an executable called xcompact3d.
Running the wind turbine 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.
For debugging or quick testing, you can reduce ilast value in iput.i3d but make sure it is set to 2000 for the final test.
