| 25 | ! 08/2016 eso: MPI version: |
---|
| 26 | ! |
---|
| 27 | ! -Root process release particles and distributes to other processes. |
---|
| 28 | ! Temporary arrays are used, also for the non-root (receiving) processes. |
---|
| 29 | ! -The scheme can be improved by having all processes report numpart |
---|
| 30 | ! (keeping track of how many particles have left the domain), so that |
---|
| 31 | ! a proportional amount of new particles can be distributed (however |
---|
| 32 | ! we have a separate function called from timemanager that will |
---|
| 33 | ! redistribute particles among processes if there are imbalances) |
