ALL Unstructured Mesh Method¶
A Load-Balancing Library (ALL) library aims to provide an easy and portable way to include dynamic domain-based load balancing into particle based simulation codes. The library is developed in the Simulation Laboratory Molecular Systems of the Juelich Supercomputing Centre at Forschungszentrum Juelich.
Purpose of Module¶
This module provides an additional method to the ALL library, up-to-date descriptions of the methods in the library can be found in the ALL README file.
In contrast to ALL Tensor-Product method and ALL Staggered Grid Method, the unstructured mesh method adjusts domains not by moving boundaries but vertices, i.e. corner points, of domains. For each vertex a force, based on the differences in work of the neighboring domains, is computed and the vertex is shifted in a way to equalize the work between these neighboring domains.
Background Information¶
See ALL (A Load-balancing Library) for details.
Building and Testing¶
See ALL: Building and Testing for details.
Source Code¶
The implementation of the method in ALL can be found in ALL_Unstructured.hpp.
The source code to the ALL library is available as a git repository at https://gitlab.version.fz-juelich.de/SLMS/loadbalancing . To obtain a copy of the repository you can use
git clone https://gitlab.version.fz-juelich.de/SLMS/loadbalancing.git
However, please note that the source code is currently under embargo until an associated paper is published, if you would like to be obtain a copy of the code, please contact Prof. Godehard Sutmann at g.sutmann@fz-juelich.de.
