The electron impact excitation rate coefficients or effective collision strengths are one of the ingredients for plasma modeling or plasma diagnosis. The present work provides a computational implementation for calculating excitation rate coefficients using the Jena Atomic Calculator toolbox within the framework of the relativistic distorted wave approximation. To address the need for large-scale calculations involving complex shells and heavy atoms and ions, parallel programming is implemented to expedite the computation of cross sections, collision strengths, effective collision strengths and rate coefficients. As a case study, we have calculated collision strengths, effective collision strengths and rate coefficients for Fe XXII.
