Hi Dominic, take a look in your_domain>conf>ems_run>run_ncpus.conf It explains how to do the partitioning. For example, if you have 20 cores, you should not use all of them. Suppose you'll use 16. You can try several configurations: 16x1 1x16 4x4 2x8 8x2 See which one is faster for the same run. The...

Hi,
did you noticed about the problem of too many processors? Try to adjust this in your configuration files ncpus.conf.
Other than this, I'd check the amount of memory it's using, but also try to check if there is some kind of CFL problem.

However, when I plot the terrain, there are missing tiles in every domain. Has someone experienced this? How can I check if the data are ok or there are miss...

Hi all, I intend to do a four-month simulation using FNL data. I'd like to know which is the minimum set of data to download from NCAR'S Research Data Archive in order to initialize UEMS, because FNL data also include lots of information which is not relevant for me now. Also, is there a way to trim...
