A MultiAgent Environment for MPSE's
In tllis paper we present a paradigm for simulaling complex phenomena which may involve multiple physical pllcnomena and complicated geometry. The computational structure is of cooperating agents and much of the proposed methodology is widely applicable, but the focus in tItis paper is on phenomena modeled by partial differential equations (PDE). The computational process is 10 subdivide the ph...
متن کاملMultiAgent Techniques for Simulation of Complex Scienti cSystemsT
In this paper we present a paradigm for simulating complex systems. Such systems, typically found in Scientiic and Engineering domains (simulating an engine, designing an airplane wing), involve multiple physical phenomena with complicated geometry. The computational techniques we propose use cooperating agents. Our focus in this paper will be on phenomenon modeled by PDEs, although much of the...
متن کاملFrom physics model to results: An optimizing framework for cross-architecture code generation
Starting from a high-level problem description in terms of partial differential equations using abstract tensor notation, the Chemora framework discretizes, optimizes, and generates complete high performance codes for a wide range of compute architectures. Chemora extends the capabilities of Cactus, facilitating the usage of large-scale CPU/GPU systems in an efficient manner for complex applica...
متن کاملModeling Stencil Computations on Modern HPC Architectures
Stencil computations are widely used for solving Partial Differential Equations (PDEs) explicitly by Finite Difference schemes. The stencil solver alone -depending on the governing equationcan represent up to 90% of the overall elapsed time, of which moving data back and forth from memory to CPU is a major concern. Therefore, the development and analysis of source code modifications that can ef...
متن کاملConception et réalisation d'un solveur pour les problèmes de dynamique des fluides pour les architectures many-core. (Design of generic modular solutions for PDE solvers for modern architectures)
Numerical simulation is nowadays an essential part of engineering analysis, be it to design a new plane, or to detect underground oil reservoirs. Numerical simulations have indeed become an important complement to theoretical and experimental investigation, allowing one to reduce the cost of engineering design processes. In order to achieve a high level of precision, one need to increase the re...
