We present the E] compiler and runtime library for the ‘F’ subset of
the Fortran 95 programming language. ‘F’ provides first-class support for arrays,
allowing E] to implicitly evaluate array expressions in parallel using the SPU coprocessors
of the Cell Broadband Engine. We present performance results from
four benchmarks that all demonstrate absolute speedups over equivalent ‘C’ or
Fortran versions running on the PPU host processor. A significant benefit of this
straightforward approach is that a serial implementation of any code is always
available, providing code longevity, and a familiar development paradigm
