abstract

PGLIB allows the
user to perform global operations within certain groups of processors, in
addition to performing global operations on the entire allocated processor
mesh. Subroutines are provided to define groups of processors, perform
arithmetic operations including maximum and minimum, logical operations
such as and, or, etc., and synchronization within each group.
