3178 | ! PURPOSE: Custom method for reducing MPI lists for OASIS using a log2 |
---|
3179 | ! algorithm. This generates a list on all tasks that consists of the intersection |
---|
3180 | ! of all the values on all the tasks with each value listed once. linp1 |
---|
3181 | ! is the input list, possibly different on each task. lout1 |
---|
3182 | ! is the resulting list, the same on each task, consistenting of all unique |
---|
3183 | ! values of linp1 from all tasks. This ultimately reduces the list onto |
---|
3184 | ! the root task and then it's broadcast. The reduction occurs via a binary |
---|
3185 | ! type reduction from tasks to other tasks. |
