Guide to run WRF on GPU

Postby mt_tech » Fri Sep 21, 2018 7:55 am

Can anyone point to instructions, steps or guide on how to compile and run WRF on a GPU ?
I found a lot of discussions around this topic but it seems there is no solid and straightforward documentation on this.
Some additional questions on this:
1) Is it possible at all to run WRF on GPU?
2) Will I see significant improvement in performance/runtime ?
3) Is there any documentation or instructions for compiling and running ?
Any help or hint is highly appreciated.

There are bits and pieces of code for GPU in WRF but zero documentation. One place that has been around
for a long time says this code is experimental and shouldn't be considered part of WRF. It is dated 2009.

There is apparently newer code, that who knows if it works. It does use a namelist setting. I also see a
couple of checks to see if RUN_ON_GPU is defined, however, setting this isn't part of any configuration

You could try asking if anything is officially supported, though I doubt it.
