improve time information in TimeLoop
Feature request
There are two small issues about the output of time information in the class TimeLoop.
-
The output format of wall clock time and other CPU times is in a low precision
{:.2g}, so it is impossible to measure the time in detail. -
(Optional) The output shows Simulation took but Time loop took seams more consistent since only the time of the time loop is measured.
For parallel computations the start-up (partitioning etc.) may take a lot of time and this time belongs also to as simulation, but is not measured by TimeLoop.
What does this feature / why does DuMux need it:
-
Change the precision to {:.5g} for Wall clock time, Simulation took and the cumulative CPU time
-
(Optional) Rename Simulation took to Time loop took
DuMux needs a higher output precision for time related information to allow users to measure the time used by the time loop for performance studies, benchmarks and checking/plotting the convergence. Making a plot of **Wall clock time** and time or time step size only works if all variables are given in a sufficient precision.
Which issue does this feature fix (if any)
Anything else we need to know?:
This issue is related to #916 (closed) I'm not sure if the formulation Simulation took has been explicitly chosen instead of something like Time loop took.
