ABSTRACT
<p>Features of an explicitly parallel programming language targeted for reconfigurable parallel processing systems, where the machine's N processing elements (PEs) are capable of operating in both the SIMD and SPMD modes of parallelism, are described. The SPMD (single program-multiple data) mode of parallelism is a subset of the MIMD mode where all processors execute the same program. By providing all aspects of the language with an SIMD mode version and an SPMD mode version that are syntactically and semantically equivalent, the language facilitates experimentation with and exploitation of hybrid SIMD/SPMD machines. Language constructs (and their implementations) for data management, data-dependent control-flow, and PE-address-dependent control-flow are presented. These constructs are based on experience gained from programming a parallel machine prototype and are being incorporated into a compiler under development. Much of the research presented is applicable to general SIMD machines and MIMD machines.</p>
