چکیده
We present the job farming mechanism of the VISTA [1] TCAD framework, which enables efficient parallel and distributed simulation. A load balancing mechanism for optimal selection of computation hosts is introduced. Strategies for controlling the load of computation hosts are presented.

Dynamic balancing of communication and computation load for HLA-based simulations on large-scale distributed systems
Dynamic balancing of computation and communication load is vital for the execution stability and performance of distributed, parallel simulations deployed on the shared, unreliable resources of large-scale environments. High Level Architecture (HLA) based simulations can experience a decrease in performance due to imbalances that are produced initially and/or during run time. These imbalances a...
متن کاملAn Algorithm for Dynamic Load Balancing of Synchronous Monte Carlo Simulations on Multiprocessor Systems
We describe an algorithm for dynamic load balancing of geometrically parallelized synchronous Monte Carlo simulations of physical models. This algorithm is designed for a (heterogeneous) multiprocessor system of the MIMD type with distributed memory. The algorithm is based on a dynamic partitioning of the domain of the algorithm, taking into account the actual processor resources of the various...

This paper addresses a dynamic load balancing method of domain decomposition for 3-dimensional Molecular Dynamics on parallel computers. In order to reduce interprocessor communication overhead, we are introducing a concept of permanent cells to the dynamic load balancing method. Molecular Dynamics simulations on a parallel computer T3E prove that the proposed method using load balancing much i...
متن کاملParallel Global Aircraft Configuration Design Space Exploration
– The preliminary design space exploration for large, interdisciplinary engineering problems is often a difficult and time-consuming task. General techniques are needed that efficiently and methodically search the design space. This work focuses on the use of parallel load balancing techniques integrated with a global optimizer to reduce the computational time of the design space exploration. T...
متن کاملSynchronous distributed load balancing on dynamic networks
In this paper, three distributed load balancing algorithms for dynamic networks are investigated. Dynamic networks are networks in which the topology may change dynamically. The definition of a dynamic network is introduced and its graph model is presented. The main result of this study consists in proving the convergence toward the uniform load distribution of the diffusion algorithm on an arb...
