How to calculate computation cost in your paper?

[HALF111]

@gorold Hi, I'm wondering that what is the context length in the table 23 in your paper, when the prediction varies from 1000 to 5000? And similarly, what is the prediction length when the context varies from 1000 to 5000? By the way, is this cost computed on the univariate time series?
In addition, if possible, could you please provide the script file or python file for calculating computation time? We also hope to reproduce the result. Thanks in advance.
