Parallel Performance of a Combustion Chemistry Simulation

Parallel Performance of a Combustion Chemistry Simulation

We used a description of a combustion simulation's mathematical and computational methods to develop a version for parallel execution. The result was a reasonable performance improvement on small numbers of processors. We applied several important programming techniques, which we describe, in optimizing the application. This work has implications for programming languages, compiler design, and ...

Computationally efficient implementation of combustion chemistry in parallel PDF calculations

In parallel calculations of combustion processes with realistic chemistry, the serial in situ adaptive tabulation (ISAT) algorithm [1,2] substantially speeds up the chemistry calculations on each processor. To further improve the efficiency of chemistry calculations in parallel computations, in this work, the ISAT algorithm is extended to the multi-processor environment, with the aim of minimiz...

National Combustion Code: Parallel Implementation and Performance

Introduction The National Combustion Code (NCC) is being developed by an industry-government team for the design and analysis of com bustion systems. CORSAIR-CCD is the current baseline reacting flow solver for NCC. This is a parallel, unstructured grid code which uses a distributed memory, message passing model for its parallel implementation. The focus of the present effort has been to improv...

Large Eddy Simulation of Combustion on Massively Parallel Machines

Combustion is the source of eighty percent of the energy produced in the world: it is therefore a topic of major interest in the present context of global warming and decreasing fuel resources. Simulating combustors and especially instability mechanisms in these systems has become a central issue in the combustion community in the last ten years. This can be achieved only on massively parallel ...
