Run single-site simulation on multiple nodes?

[jinmuluo]

Hi community,

I'm wondering can I run a single site simulation case by using multiple nodes? Does it help to accelerate the simulation speed? If it can be done, how to specify the name list var? Thank you !

best,

Jinmu

The short answer is no. One grid-cell can only use one processor, so it won't help to give more.

The longer answer is that the one thing you could do is to run multi-instance to run more than one case at the same time. You probably wouldn't want to run multiple sites this way with differences between start and stop times, but that might be useful to do simulations to calibrate parameters. But, the other disadvantage with this is that if any of the cases fail -- it will shut the other instances down. So in the end, I'm not sure this is helpful.

In terms of speeding up single site simulations, using forcing data that has only one point is helpful. And if you are running with BGC it would help to trim down the lightning dataset to a single point as well.

Thank you Erik, could you please tell me how to trim down the lightning dataset?

We do not support such a thing. You will need to use python or matlab or ncl or whatever you use to modify netcdf files.

@erik please correct me if I'm wrong.
