Payu run but skip collate

Hi,
I have an application where I want to run MOM5 model using payu, but I’m only interested in the restart files and don’t care about diagnostic outputs. Thus, I would like to find a way to make payu completely bypass the collate step, because I just need to run a postscript that will extract restart information and then delete the output folder and the restart folder (then modify the original restart and resubmit as if it’s the “same” run).

Is there a way to tell payu not to do collate? Please help

Thanks, Dave

Hi Dave,

Thank you for reaching out!
Yes, you can definitely turn off collation by setting the config.yaml as

collate: false

Please give it a try and let me know if it works for you :slight_smile:

Best,

Thanks @Qianhui_Chen, that is great to know! I will try it.

You are very welcome Dave!

On top of this, if you don’t need the diagnostic output at all, you could choose to turn off diagnostics completely. This will make your model run even faster. Please let me know if this is something that you are interested.

Best,
Qianhui

Thanks Qianhui! I suppose that would mean just making the diag_table an empty file?

Could I confirm whether you are running MOM5 only, or is there any other components involved, such as ESM1.5?

This particular case is MOM5 only.

For MOM5 only experiment, we can remove most of the diag_table and only leave the first two lines (i.e., experiment string and the base date). Hopefully this can help fasten your runs :slight_smile:

Awesome, thanks again Qianhui!
