Concepts for Flexible Parallel Multi-domain Simulations
Christian Engwer,Steffen Müthing +1 more
- 01 Jan 2016
TL;DR: This work presents an abstraction that hides this non-locality and allows the user to implement his Domain Decomposition strategy in a clear mathematical setting, without the necessity to directly deal with the aspects of parallel computations.

Extension of CHIMPS for Unstructured Overset Simulation and Higher-Order Interpolation
Seonghyeon Hahn,Gianluca Iaccarino,Shreyas Ananthan,James D. Baeder +3 more
- 22 Jun 2009
TL;DR: A majority of multi-physics-coupled applications concerns a situation where different physical phenomena occur locally in space, and a flexible integration infrastructure in which several independent solvers can be easily coupled with one another is more advantageous than to newly implement all the necessary functionalities and physical/numerical models onto a single code.

Rendezvous algorithms for large-scale modeling and simulation
TL;DR: This work describes how rendezvous algorithms work in a scientific computing context and gives specific examples for molecular dynamics and Direct Simulation Monte Carlo codes which result in dramatic performance improvements versus simpler algorithms which do not scale as well.

Enhancing performance and scalability of data transfer across sliding grid interfaces for time-accurate unsteady simulations of multistage turbomachinery flows
TL;DR: This paper redesigns the algorithm in such a way that it maintains the scalability of the original CFD code on static grids and proposes a deterministic geometric decomposition on an intermediate “rendezvous” set of processes.

A Fast and High Quality Multilevel Scheme for Partitioning Irregular Graphs
George Karypis,Vipin Kumar +1 more
TL;DR: This work presents a new coarsening heuristic (called heavy-edge heuristic) for which the size of the partition of the coarse graph is within a small factor of theSize of the final partition obtained after multilevel refinement, and presents a much faster variation of the Kernighan--Lin (KL) algorithm for refining during uncoarsening.
A Partitioning Strategy for Nonuniform Problems on Multiprocessors
TL;DR: This work uses a binary decomposition of the domain to partition it into rectangles requiring equal computational effort, and studies the communication costs of mapping this partitioning onto different multiprocessors: a mesh- connected array, a tree machine, and a hypercube.
