WRF EMS and Infiniband?

[Akio]

Hi,

at first thank you all for this very helpful knowledgebase! It helps me a lot to solve my problems I had in the beginning of using the WRF model.
I'm actually trying to configure a WRF EMS model on an Infiniband connected Cluster. I already installed the OFED. But how can I configure the WRF EMS to use the Infiniband for clustering? Are there any HowTos?

Thank you very much for your answers!

Hi,

has no one any experience with running the wrf ems version on an infiniband cluster?

Thank you very much!

Hi,

Unfortunately, I don't think anyone who is active here on this board has worked with infiniband cluster. But, maybe.. never know... you can wait and see if someone really does come up with some help.

Hi,

I don't have WRF EMS experience but I do have WRF + Infiniband experience.

It's all about how you pass options to mpirun - ideally compiled with openMPI + infiniband support.

Typically it goes like this:
mpirun --mca btl openib,self $PATH2WRF/wrf..exe


Hope that helps!
