Pfortran and PC Translators

Abstract

PROJECT DESCRIPTION: The Pfortran programming approach eases the task of writing parallel programs for massively parallel computers by providing constructs to coordinate non-local memory accesses. At Pfortran's center is an operator that specifies the location of off-processor variables and an operator for aggregate operations. Portability and ease of programming are achieved by unifying off-processor accesses with the guarded-memory model. Because the programmer writes low-level node code with Pfortran, the loss in performance compared to using the lowest-level primitives is typically negligible. A number of well-known computational chemistry programs parallelized with Pfortran are now in production use on massively parallel computers, with several research groups now contributing to the ongoing development. Recently, a prototype of PC++ has been developed, with further refinements to the P-language concept.
