| subroutine, public | qs_fb_com_tasks_types::fb_com_tasks_set (com_tasks, task_dim, ntasks, nencode, tasks) |
| | Sets attributes in a fb_com_tasks object, one should only access the data content in a fb_com_tasks object outside this module via this procedure. More...
|
| |
| subroutine, public | qs_fb_com_tasks_types::fb_com_tasks_transpose_dest_src (tasks_dest_is_me, direction, tasks_src_is_me, para_env) |
| | Start from a local set of tasks that has desc/src process equal to the local MPI rank, communicate with other processes so that a new local set of tasks is constructed with src/desc process equal to the local MPI rank. More...
