[FAQ]

The total elapsed time refers to the clock time of the entire simulation. The solver time is the CPU time spent on solving the model. Their difference is called Edit Time, when the program saves the results, exchanges the data between the slaves (cores). Edit time is not done by parallel processing. If a large difference is observed between the Elapsed Run Time in Solver and the Total Elapsed Run Time, user should check the output frequency of results trackers and results files. If the results trackers are saved at every cycle and the simulation will run a very large number of cycles such as 100,000 or more, user is suggested to reduce the output of results trackers by increasing save frequency from every 1 cycle to every 10 or more cycles in Output Controls under Analysis Settings. This will effectively reduce the edit time and thus increase the HPC performance.
