     CH01
Data-parallel computation
             (bit parallel)
Application of Data-parallel Architectures:
      One data entity processed by one PE
Connectivity
Near-neighbor connectivity
               (2-D: Mesh)
Tree: 2-D hierarchy
Pyramid: 3-D hierarchy
Hypercube: 2^N nodes in N
               dimension
                  Hypercube: 4-D
Long and short-range connections
Data-parallel approaches
Principal characteristics of data-parallel
