Main objective of
this paper is to outline possible ways how to achieve a substantial
acceleration in case of advectiondiffusion equation (ADE) calculation, which
is commonly used for a description of the pollutant behavior in atmosphere.
ADE is a kind of partial differential equation (PDE) and in general case it is
usually solved by numerical integration due to its high complexity. These types
of calculations are time consuming thus the main idea of our work is to adopt
CUDA platform and commodity GPU card to do the calculations in a faster way.
The solution is based on method of lines with 4th order RungeKutta
scheme to handle the integration. As a matter of fact, the selected approach
involves number of auxiliary variables and thus the memory management is
critical in order to achieve desired performance. We have implemented several
possible solutions that use different memory access schemes. Detailed
evaluation is provided in this paper where the obtained results show a tremendous
processing speed up in comparison to CPU.
