| 25 | ! Initial revision. |
|---|
| 26 | ! Routine re-written and optimised based on poismg. |
|---|
| 27 | ! |
|---|
| 28 | ! Following optimisations have been made: |
|---|
| 29 | ! - vectorisation (for Intel-CPUs) of the red-black algorithm by resorting |
|---|
| 30 | ! array elements with even and odd indices |
|---|
| 31 | ! - explicit boundary conditions for building walls removed (solver is |
|---|
| 32 | ! running through the buildings |
|---|
| 33 | ! - reduced data transfer in case of ghost point exchange, because only |
|---|
| 34 | ! "red" or "black" data points need to be exchanged. This is not applied |
|---|
| 35 | ! for coarser grid levels, since for then the transfer time is latency bound |

|---|
| 45 | ! Solves the Poisson equation for the perturbation pressure with a multigrid |
|---|
| 46 | ! V- or W-Cycle scheme. |
|---|
| 47 | ! |
|---|
| 48 | ! This multigrid method was originally developed for PALM by Joerg Uhlenbrock, |
|---|
| 49 | ! September 2000 - July 2001. It has been optimised for speed by Klaus |
|---|
| 50 | ! Ketelsen in November 2014. |
