A method and apparatus for computation is provided. A main cluster crossbar is
connected to a plurality of statically scheduled routing processors. A first sub-cluster
crossbar is associated with a first one of the plurality of statically scheduled
routing processors where the first sub-cluster crossbar is connected to a first
plurality of execution processors. A second sub-cluster crossbar is associated
with a second one of the plurality of statically scheduled routing processors where
the second sub-cluster crossbar is connected to a second plurality of execution processors.
