HI,WRF forum!
I met a problem when I tried to run a wrf model. I am using mpirun -np 72 ./wrf.exe, i tried with mpirun -np 96./wrf.exe, but my model runs very slow almost 1 hours simulation take 2.5 hors to complete. How can choose the effective no. of processor for faster run. Currently m following:
For your largest-sized domain
(e_we)/100) * ((e_sn)/100) = least amount of processors you should use.
For your smallest-sized domain(e_we)/25) * ((e_sn)/25) = most amount of processors you should use.
this rule to choose the no. of processors but still its low. I am attaching my namelist.input file & job script. I request you to kindly look into it. and tell me what changes should be made for faster run.
Thankyou
