A Domain-Decomposition-Free Parallelisation of the Fast Marching Method
نویسندگان
چکیده
The Fast Marching Method (FMM) is an efficient technique to numerically solve the eikonal equation. The parallelisation of the FMM is not easy because of its intrinsic sequential nature. In this paper we propose a novel approach to parallelise the FMM which is not based on a classic domain-decomposition procedure. Compared to other techniques in the field, our method is much simpler to implement and initialise. By numerical experiments we show that it gives in addition a slightly better computational speed-up. Making use of an example from the field of computer vision, we verify that the favourable properties of our approach are useful for real-world applications.

Shared-memory parallelization of the fast marching method using an overlapping domain-decomposition approach
The fast marching method is used to compute a monotone front propagation of anisotropic nature by solving the eikonal equation. Due to the sequential nature of the original algorithm, parallel approaches presented so far were unconvincing. In this work, we introduce a shared-memory parallelization approach which is based on an overlapping domain decomposition technique. We introduce our paralle...
متن کاملمسیریابی حرکت روباتهای ماشینواره با روش پیشروی سریع
The Robot Motion Planning (RMP) problem deals with finding a collision-free start-to-goal path for a robot navigating among workspace obstacles. Such a problem is also encountered in path planning of intelligent vehicles and Automatic Guided Vehicles (AGVs). In terms of kinematic constraints, the RMP problem can be categorized into two groups of Holonomic and Nonholonomic problems. In the first...
متن کاملA level set simulation of dendritic solidification of multi-component alloys
A level set method combining features of front tracking methods and fixed domain methods is presented to model three-dimensional microstructure evolution in the solidification of multi-component alloys. Phase boundaries are tracked by solving the multi-phase level set equations. Diffused interfaces are constructed from these tracked phase boundaries using the level set functions. Based on the a...
متن کاملSemi-automatic Parallelisation of Unstructured Mesh Codes Using Domain Decomposition
In this paper we discuss enhancements to a suite of semi-automatic parallelisation tools to enable unstructured mesh (irregular) computational mechanics (CM) codes to be rapidly parallelised using SPMD domain decomposition techniques. This work draws upon the dependence analysis and code generation techniques that were originally developed for structured mesh (regular) FORTRAN codes and have be...
متن کاملStochastic Reduced-order Model for Dynamical Structures Having a Modal Density in the Low Frequency Range
This paper is devoted to the construction of stochastic reduced-order model for dynamical structures having a high modal density in the low-frequency range. We are particularly interested in automotive vehicles which are made up of stiff parts and flexible components. This type of structure is characterized by the fact that it exhibits, in the low-frequency range, not only the classical global ...
