Function is called whenever nprocs > no_task. Function returns only the subset of processors that are closest to each other.

Parameters:

proc_permutation	holds the indices of the processors that are chosen.
nprocs	the number of processors.
ntasks	the number of taks.

Parameters:

proc_to_task_xadj	holds the pointer to the task array
