DRIHM meteorological models is based on WRF (Weather Research and Forecasting). WRF is a community model with open source license.

WRF requirements for EGI sites:

  • 160-240 processors, but the simulations can be designed also to run on 50-100 processors
  • about 24 hours of physical simulation time, to an elapsed time of a single run of 144--96 hours (6--4 days).
  • Temporary disk space (GB): 80 GB for input, output, which corresponds to 24 h physical time, saving the data every 30 minutes of physical time. 28 GB for restart files, saving files every 6 hours of physical time.
  • submission is through the DRIHM portal, based on SCI-BUS (
