Using GPU acceleration in solving selected kinetic coal gasification models
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2016, Vol 526, Issue 2
Abstract
Coal gasification is recognized as one of clean coal technologies. Though it has been known for a relatively long time, its complexity still challenges scientists all over the world. One of the tools used in the research is simulation. The presented work investigates the capabilities of using GPGPU in modeling coal gasification. The selected set of models is used (volumetric, non-reactive core and Johnson’s). The models as well as numeric solution methods were implemented as a sequential and parallel code. The execution time for both methods was investigated and the speedup for the parallel code determined. The influence of mathematical function call in the GPU code was also checked. The results show that for all models the parallel code gives significant speedup over the serial counterpart, as long as a reasonably large equation set is used. Therefore, using a dedicated GPU code for coal gasification simulations is highly recommended, whenever big systems of ODE have to be solved.
