Comparison of simulation run times¶
Comparison of run times of the current version of MODFLOW 6 (6.4.0) to the previous version (6.3.0). The current example models available from the MODFLOW 6 Examples GitHub Repository are used to compare run times. Simulations that fail are indicated by ‘–’. The percent difference, where calculated, is relative to the simulation run time for the previous version. Percent differences for example problems with short run times (less than 30 seconds) may not be significant.
MODFLOW 6 compiled Dec 1 2022 14:46:13 with GCC version 10.4.0.
