 Here is an example large problem size that you can run on one GPU:
 
-    $ mpirun -np 1 ./BP/BP5/BP5 -m HIP -nx 24 -ny 24 -nz 24 -p 14 -v
+    $ mpirun -np 1 ./BP/BP5/BP5 -m HIP -nx 24 -ny 24 -nz 24 -p 15 -v
 
 Running on multiple GPUs can by done by passing a larger argument to `np`:
 
-    $ mpirun -np 4 ./BP/BP5/BP5 -m HIP -nx 24 -ny 24 -nz 24 -p 14 -v
+    $ mpirun -np 4 ./BP/BP5/BP5 -m HIP -nx 24 -ny 24 -nz 24 -p 15 -v
