Is it possible to run WRF Without I/O (Writing)?

[matician09]

Hi everyone, I am trying to measure performance of WRF with some kind of benchmark set.

Ideally, to control variability in the system's I/O performance, I would like to run only the minimum required input reads and avoid any output writes. However, when I set history_interval as 0,0,0 or 10000,10000,10000 (too big numbers) and run the model, WRF terminates just successfully without performing the main computation. (It appears that at least Domain 1 must be configured for the run to actually execute.)

Would anyone be able to offer advice or share good ideas on how to properly measure computational performance?

I guess I found some kind of solution for the title question.
My iofields_empty file seems to function correctly for executions without any writing. The namelist includes iofields_filename = "iofields_empty", and the file contains the following entries.
