Dear All,
NGIs have received a request to ask their sites to consider supporting the DRIHM project (the request/requirements are in the forwarded message below). The project aims are described in http://www.drihms.eu/drihm-kick-off-meeting but briefly it concerns "predicting weather and climate and its impacts on the environment, including hazards such as floods and landslides". I do not see any UK partner sites in the 4 main collaborating research collaborations that form DRIHM, but there may be some (or could be given the landslides component) and contributing does not require UK academic involvement, though it is a bonus. There is a requirement for MPICH2 (or MPICH or OpenMPI). Although I do not expect a massive response to the enablement request, this prompts me to check which sites have or are considering enabling MPI in the near future - I suspect we will getting increasing requests for it. Please let me know if you are interested in getting involved in this EGI collaboration or if you have MPI plans.
Many thanks,
Jeremy

> I would like to inform you about the collaboration that EGI is establishing with the Distributed Research Infrastructure for Hydro-Meteorology Study (DRIHM) project (http://www.drihm.eu/).
>
> 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.
>
> The list of requirements for running the WRF simulation model in a site follow, for your information.
>
> We are seeking for NGI support to the DRIHM testing activities.
> So far we identified 5 sites (in Serbia, Greece, France and Italy)
> that according to the information published meet the most stringent case.

> - CE: ce-01.roma3.infn.it (MPICH + MPICH2)
> - CE: ce64.ipb.ac.rs (only MPICH2)

> - CE: cream02.athena.hellasgrid.gr (only MPICH2)
> - CE: ipngrid04.in2p3.fr (only MPICH2)

> I would like to proceed by contacting the sites listed above to collect information about their interest in supporting this new user community.

> 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/)
