Parallel Memory System for a Partitionable Simd/mimd Machine
نویسندگان
چکیده
PASM is a large-scale partitionable SIMD/MIMD multimicroprocessor system being designed for image processing tasks. To improve machine throughput, a memory management system employing parallel secondary storage devices and double-buffered primary memories has been devised. The memory system is an intelligent one, using communicating microprocessors which are dedicated to handling data requests and file management. The memory system bus structure is organized to exploit much parallelism in transferring data from the secondary memories to the primary memories of virtual SIMD and MIMD machines.

Control of a Partitionable Multimicroprocessor System
A dynamically reconfigurable large-scale multimicroprocessor system capable of operating as one or more independent SIMD (single instruction stream multiple data stream) machines and/or MIMD (multiple instruction stream multiple data stream) machines is described. The system consists of a Parallel Computation Unit, which contains N processors, N memory modules, and an interconnection network; Q...
متن کاملExtensions to the C Programming Language for SIMD/MIMD Parallelism
A superset of the C programming language that is applicable to the SIMD/MIMD mode processing environment of PASM is described. The language extensions for SIMD mode include the definition of parallel variables, functions, and expressions; a scheme for accessing parallel variables; and extended control structure semantics. Extensions for MIMD mode are realized by defining a preprocessor to conve...
متن کاملThe Rewrite Rule Machine Node Architecture and Its Performance
The Rewrite Rule Machine (RRM) is a massively parallel MIMD/SIMD computer designed with the explicit purpose of supporting veryhigh-level parallel programming with rewrite rules. The RRM’s node architecture consists of a SIMD processor, a SIMD controller, local memory, and network and I/O interfaces. A 64-node cluster board is already an attractive RRM system capable of extremely high performan...
متن کاملCompiling Rewriting onto SIMD and MIMD/SIMD Maschines
We present compilation techniques for Simple Maude, a declarative programming language based on Rewriting Logic which supports term, graph, and object-oriented rewriting. We show how to compile various constructs of Simple Maude onto SIMD and MIMD/SIMD massively parallel architectures, and in particular onto the Rewrite Rule Machine, a special purpose MIMD/SIMD architecture for rewriting. We sh...
متن کاملA Comparative Study of the Programmability of a Signal Processing Application in an MIMD and an SIMD Multiprocessor
In this report, we address the issues of compilation and execution of a functional program, SISAL (Streams and Iterations in a Single Assignment Language), on the MP-1TM SIMD (Single Instructionstream Multiple Data-stream) parallel machine. SISAL has been successful on many shared memory multiprocessors (SMM) as well as sequential machines. However, the compiler has not been available for distr...
