| 46 | ! 08/2016 eso: MPI version: |
---|
| 47 | ! |
---|
| 48 | ! -Root process release particles and distributes to other processes. |
---|
| 49 | ! Temporary arrays are used, also for the non-root (receiving) processes. |
---|
| 50 | ! -The scheme can be improved by having all processes report numpart |
---|
| 51 | ! (keeping track of how many particles have left the domain), so that |
---|
| 52 | ! a proportional amount of new particles can be distributed (however |
---|
| 53 | ! we have a separate function called from timemanager that will |
---|
| 54 | ! redistribute particles among processes if there are imbalances) |
