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 ...
متن کاملComparing CM Fortran and Message-Passing Fortran Programming Modes on the CM-5
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 the design and implementation of benchmarks which were used to bring out the diierence in speed between the two programming modes with CM Fortran and message-passing Fortran. Tw...
متن کاملCharon toolkit for parallel, implicit structured-grid computations: Functional design
1 Introduction In a previous report the design concepts of Charon 5] were presented. Charon is a toolkit that aids engineers in developing scientiic programs for structured-grid applications to be run on MIMD parallel computers. It constitutes an augmentation of the general-purpose MPI-based 4] message-passing layer, and provides the user with a hierarchy of tools for rapid prototyping and vali...
متن کاملCompiler Support for Machine - IndependentParallel Programming in
Because of the complexity and variety of parallel archi-tectures, an eecient machine-independent parallel programming model is needed to make parallel computing truly usable for scientiic programmers. We believe that Fortran D, a version of Fortran enhanced with data decomposition speciications, can provide such a programming model. This paper presents the design of a prototype Fortran D compil...
متن کاملCalculation of Absorbed Glandular Dose using a FORTRAN Program Based on Monte Carlo X-ray Spectra in Mammography
Introduction: Average glandular dose calculation in mammography with Mo-Rh target-filter and dose calculation for different situations is accurate and fast. Material and Methods: In this research, first of all, x-ray spectra of a Mo target bombarded by a 28 keV electron beam with and without a Rh filter were calculated using the MCNP code. Then, we used the Sobol-Wu parameters to write a FORTRA...
