• Abstract:
  Array privatisation is usually viewed as being one of the most important loop transformations in automatic parallelisation. This paper takes the view that each array or data structure in a scientific program can be prejudged as being either shared or privatised based on what it's data represents. Consequently, this property, the structure's plurality, is constant throughout the program. Far from being restrictive, it is argued that this concept aids the parallelisation process. The theory has been used in the construction of an interactive compiler for Fortran 77. Results are presented for the parallelisation of the SPEC CFP95 benchmarks by the prototype compiler.
