Nested MIMD-SIMD Parallelization for Heterogeneous Microprocessors

Parallel Image Processing on Heterogeneous SIMD-MIMD Machines

From a hardware standpoint a heterogeneous architecture such as an SIMD array coupled onto a MIMD system, will yield a powerful solution for real time embedded vision tasks. From a software standpoint there is a need to approach this heterogeneous system in a homogeneous way. We investigated the feasibility of a uniform parallel programming approach on a heterogeneous machine. Using the paralle...

Realizzazione di modelli di varie architetture di calcolatori paralleli (di tipo SIMD, MIMD e ibridi) e loro validazione sperimentale To Floriana Acknowledgments I would like to thank my supervisor Prof. Giuseppe Serazzi for the inspiration , guidance, friendship ooered throughout my studies. I feel a special gratitude towards Peter King and Paolo Cremonesi for their important contribution to t...

Comparing SIMD and MIMD Programming Modes

| The Connection Machine CM-5 supports both SIMD and MIMD programming modes. The SIMD mode is simulated over the MIMD mode. This simulation is likely to lead to a loss of performance in SIMD programs. This paper describes a comparison of the two programming modes with CM Fortran and message-passing Fortran. Two kinds of benchmarks are discussed. The rst kind consists of synthetic benchmarks in ...

Compiling 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...
