How can I run different WRF simulations at the same time?

Post by vvidal » Mon May 04, 2020 3:03 pm

Hello everybody!

I need to run different WRF simulations at the same time. I need to study the scalability and performance of WRF-chem, and my idea is to run multiple times WRF with different parameters and also a different number of cores.

Is it possible to run it at the same time without making a copy of the WRF folder?

Thank you in advanced,

Verònica.

Hi Verònica,
Unfortunately I'm not aware of a way to do this at the same time from the same directory. You could run the runs back-to-back by writing a script to ingest the different namelists and output into different directories (so as to not overwrite anything). You may be able to find some better guidance by doing a web search to see if anyone else has been able to do same-time ensemble runs without having multiple directories. Or perhaps someone else on this forum will be able to chime in about success they've had.
