What function is used to calculate the time of the main functions in the atmospheric chemistry module

[Peter0728]

Hello everyone, please help me. I want to count the hot functions in the atmospheric chemistry module, the number and time of calls to the main functions, and what built-in functions should I use to measure them. Are they the t_startf and t_stopf functions? What functions should I use to measure time and how to use the built-in timing function.

yes, t_startf and t_stopf are the built in timers. You might also consider using external tools such as gprof or intel-vtune

Thank you for your answer. I want to measure the timing time of the atmospheric chemistry module, chemistry under Mozart Add 'use perf_mod' and 'call t_startf' ('chemr ') to the F90 file, but the timing file does not include the time of' chemr '. There are two questions that need your help to solve. Do you know which files should be measured for the time of the atmospheric chemistry module? How should t_startf and t_stopf be used to display time in the timing file?
