چکیده
Abstract The development, validation, and applications of an object-oriented free-wake solver for multi-rotor fixed-wing systems are outlined here. Advantages utilizing the philosophy modeling multi-rotor/wing problem described. To explore feasibility conventional desktop workstations, vortex lattice methodology’s time complexity is examined as evolving n-body advantage gained from employing wake roll up models demonstrated. Modifications in typical formulae to leverage features multi-core improvements computational performance obtained these modifications illustrated using a roofline analysis. incorporating optimizations then employed—after extensive validation—to simulate distributed propulsion aircraft urban mobility vehicle. paper also proposes novel skew parameter monitoring instabilities solutions commonly observed rotorcraft

POEMS: A Parallel Object-oriented Environment for Multi-computer Systems
POEMS is a Parallel Object-oriented Environment for Multi-computer Systems. In order to support dynamic load balancing, its runtime execution model is based on object replication. Method invocation in POEMS is asynchronous and threads are created to execute methods. Inter-object, intra-object as well as intra-method parallelism are all supported. Programs in POEMS are written using two classes ...
متن کاملParallel object-oriented framework optimization
ion could not be expected to be optimized by any serial compiler, moreover all of the specific user-defined semantics defined by any library abstraction are ignored within compilation because the compiler only understands the semantics of the language in which the abstraction is implemented. The potential for the optimization of abstractions and their interaction depends heavily upon the charac...
متن کاملDesigning a Parallel Object Oriented Graphics Framework
This paper aims to present a design strategy for graphics frameworks, that facilitates easy parallelization. This is achieved by introducing two mechanisms for dealing with the main issues of parallelization, that can be seamlessly integrated into graphics frameworks which have been designed adhering to a few implementation rules. These two main mechanisms are Remote Access Nodes, that mainly d...
متن کاملA Multi-Paradigm Object Oriented Parallel Environment
Control and data parallelism are two complementary but often mutually exclusive paradigms used to program massively parallel systems. We propose to encapsulate both control and data parallelism in regular classes of a sequential Object Oriented language: a SPMD programming model is used and thus no language extensions are needed, provided a Shared Virtual Memory is available. We show how these ...
متن کاملA Parallel Object-Oriented Framework for Stencil Algorithms
We present an object-oriented framework for constructing parallel implementations of stencil algorithms. This framework simplifres the development process by encapsulating the common aspects of stencil algorithms in a base stencil class so that application-specifre derived classes can be easily defined via inheritance and overloading. In addition, the stencil base class contains mechanisms for ...
