PDDP: A Data Parallel Programming Language Tool

description

http://www.nersc.gov/doc/Parallel_Processing/pddp.html
The Parallel Data Distribution Preprocessor (PDDP) language
translator provides a model similar to High Performance Fortran
compilers for users of massively parallel Multiple Instruction
Multiple Data computers.
In the absence of High Performance Fortran compilers, PDDP
allows scientists using HPF-like coding to quickly port their codes
to massively parallel computers. Our Parallel Data
Distribution Preprocessor (PDDP) model provides an HPF-subset
offering efficient performance on massively parallel processors
(MPPs) with nonuniform memory access (NUMA). When HPF
compilers do arrive, PDDP codes will require few changes.
PDDP is a simple model that separates the layout of data from the
actual algorithm, allowing the algorithm to be described in Fortran
90 array syntax notation.
