A New Compiler Technology For Handling Hpf Data Parallel Constructs

This paper concentrates on the description of the Parallelization Engine (PE) that is responsible for the restructuring of HPF programs and for the SPMD code generation. The methods used by the PE for processing HPF codes are presented: the implementation of HPF distributed arrays and the compilation techniques are discussed. According to the access functions used in distributed array references (regular or irregular case), the compiler applies two different techniques detailed in the subsequent sections. The work described in this paper was carried out as part of the European ESPRIT project EP 6516 PREPARE. 2 ALLOCATING AND REFERENCING HPF DISTRIBUTED ARRAY
