PSI Compiler

abstract

The PSI Compiler is a compiler that performs algebraic reductions on array
expressions based on Mullin's Psi Calculus. These reductions eliminate
unnecessary computation and temporary storage. The compiler also partitions
and maps subarray operations implicity across a group of processors, be they a
network of workstations, the processors of a hypercube, or some other
topology, in a portable and scalable way. Although the input language is not
sufficient for general purpose programming, the goal of the project is to
provide a back-end for scientific array based langauges such as High
Performance Fortran. Work has been done to translate subsets of
FORTRAN90 as well as SETL into our input grammar, allowing them access
to the compiler. Also work is currently under way in order to provide an
interface between High Performance Fortran and the Psi-Compiler.
