ABSTRACT
The main objective of the study is to develop a reactive-transport model able to utilize HPC resources. The primary purpose is constructing a mathematical representation of a proposed reactivetransport system in order to simulate the potential risk of environmental contamination. Additionally, the contribution of the study is not only associated with HPC usage but also with new model features implemented during the developing phase. Overall, the Transport-Reaction Model (TRM) was developed to include complex functionality that is necessary in order to solve specific transport-reaction issues. TRM is based on coupling the PhreeqcRM geochemical library with 2D solute species transport in water on a regular rectangular network of elements. Compared to the other similar models, our model offers a unique feature that is associated with the 2D mesh. This feature represents an innovative component that improved our modelling results. Testing revealed that TRM provides conditions for simulation acceleration up to 16 threads. The further addition of resources to 20 or 24 also speeds up the calculation but decreases the efficiency of the parallel solution. Generally, the TRM is optimally run on 16 threads.
