Welcome to the page of the EGI-DRIHM collaboration



General Project Information

  • 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)

Motivation

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). A DRIHMS VO will be soon created. We are seeking for Resource Centres who are willing to provide resources for the run of the DRIHM meteorological models WRF - Weather Research and Forecasting. WRF is a community model with open source license.

WRF requirements for EGI sites:

  • MPICH or MPICH2 or OPENMPI
  • WRF model can work both with Distributed-Memory Parallelism and Shared-Memory Parallelism, with different combinations of compilers (PGI, INTEL, gfortran/gcc and so forth). WRF should be provided with mpich or mpich2 and ifort, icc (or as alternative gfortran, gcc) to ensure the best scalability and portability performances for this modeling suite. Additional WRF dependencies for weather specific formats: NetCDF, GRIB2.
  • 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/)

Progress

CONFIRMED SITES

List of sites which did confirm of their interest and participation:

Croatia

  • 3 sites, not supporting MPI at the moment but will do in a short time, DRIHM will be enabled then
  • Contact: Emir Imamagic

Germany

  • LRZ already supported initial testing of the hydro simulations

Greece:

  • all mpich2 sites (TODO: define exact list)
  • contact: Kostas

Italy

  • IGI-BOLOGNA. Level of parallelism offered: 48-64 nodes
    • cream-01.cnaf.infn.it:8443/cream-pbs-prod-sl5 (SL5 - no infiniband - 24 core per node - 80 GB per node)
    • cream-02.cnaf.infn.it:8443/cream-pbs-test-sl6 (SL6 -no infiniband - 24 core per node - 80 GB per node)
    • Issues reported by D. Cesini in compiling WRF code on SL6
  • NAPLES: level of parallelism offered: 48-64 nodes
    • emi-ce01.scope.unina.it:8443/cream-pbs-hpc (SL6 infiniband enabled - 8 core per node - 16GB per node)
  • NAPLES, ROma3 INFN (tentative, sys admins being contacted)
  • Contact: Daniele Cesini
  • Note: Daniele reported that site IGI-BOLOGNA will be used by DRIHM to use virtualized resources using the WNODES technology (DRIHM needs virtual machines requiring windows as suppor OS)

Macedonia:

  • MK-03-FINKI
  • contact: Boro Jakimovski

Serbia:

  • AEGIS01-IPB-SCL site (hosting cream.ipb.ac.rs, ce64.ipb.ac.rs).
  • contact: Antun Balaz

Spain

  • cream.egi.cesga.es (only MPICH2)
  • contact: Esteban Freire
