In this work, a restructuring of the calls of the direct model solver was carried out to remove redundant executions of the symbolic and numerical factorization stages present in the original implementation of the chemistry module from BRAMS regional numerical weather prediction. In the case study chosen, this change resulted in a gain of approximately 37.5% on average of the chemistry iteration serial time.
