Dear WRF help team,
I am running mulyear wrf simulations with WRFV3.7.1. First, i run the wrf on two clusters, one with 4 nodes, the other is national computing centers with 2000 more nodes. I compiled the wrf with same configuration and compiler. I thought it should have procude identical output with identical wrfinput, wrfbdy files and namelist.input. Actually, outputs were not identical. How could this happen? What should I do? I was doing simulations in the cluster with 4 nodes, and recently i want to change to national computing centers. The results are not consistent before and now, should I rerun the all the simulations on the new cluster?
Thanks a lot
Best, longfei
