General Project Information

DRIHM project

  • DRIHM aims for facilitating the access to hydrometeorological data and models, the collaboration between meteorologists, hydrologists, and Earth science experts for accelerated scientific advances in hydrometeorological research (HMR).
  • Leader: Antonio Parodi (antonio.parodi @ cimafoundation.org)

EGI-DRIHM collaboration

  • Leader: Tiziana Ferrari (tiziana.ferrari @ egi.eu)
  • Start Date: 17.05.2013
  • End Date:
  • Mailinglist: egi-drihm @ mailman.egi.eu
  • Meetings: Indico page (slides and minutes from meetings)

Requirements

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:

  • MPICH or MPICH2 or OPENMPI
  • 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 (http://www.sci-bus.eu/)

Virtual organization

  • DRIHM VO is in production
  • ID Card: https://operations-portal.egi.eu/vo/update/283
  • vousers at drihm.eu: Write to all VO users

  • vosecurity at drihm.eu: Write to security representatives of the VO
  • vomanagers at drihm.eu: Write to VO managers
