Download Meso-NH in binary standalone mode for DRIHM GRID


beta binary version of MNH 4-9-3 DRIHM_V0

  • Download the tar-ball MNH_DRIHM_V0.tar.gz file ( 180 MB ) , and untar it where you want

  • tar xvfz MNH_DRIHM_V0.tar.gz 


Test Case


Without physiographic :: 002_3Drelief

  • Download the tar-ball 002_3Drelief test case file ( 5.3KB ) , and untar it where you want

  • tar xvfz PACK-002_3Drelief.tar.gz
  • download the test.sh file ,and run it

  • /!\ in this the ROOT_MESONH variable must point to the directory where the MNH binaries MNH_DRIHM_V0 was untarred

  • ...
    #
    # ROOT_MESONH = where MNH binaries  MNH_DRIHM_VO was untared 
    #
    #export ROOT_MESONH=~/bin/MNH_DRIHM_V0
    export ROOT_MESONH=`pwd`/MNH_DRIHM_V0
    ...

With physiographic :: 007_16janvier

  • Download the tar-ball 007_16janvier test case file ( 23MB ) , and untar it where you want

  • tar xvfz PACK-007_16janvier.tar.gz
  • download the test.sh file ,and run it

  • /!\ In this test case, the first time, the 001_pgd1/get_pgd_files script will fetch via wget the physiographic files = 5 GB untarred, in the ~/PREP_PGD_FILES_WWW directory .

  • This script wait for an answer from the terminal for cancellation crt-C if not enough space is available . Must by adapted if no interactive session is done .

    • For example the and of test.sh could be rewrite like this

  • #
    # run the testcase
    #
    ...
    ./run_007_16janvier < /dev/null


Real MesoNH Drihm Case0

  • download the mesonh_real_drihm0.sh file , (rename it to test.sh if needed ) and run it .

  • Data will be fetch via wget from our MesoNH WEB site <=> 3GB for static PGD files + 1.5 GB for GRIB Time dependent files .

/!\ bandwidth problem now fixed about 10MB/sec expected , tell me (Juan) if not the case ...

  • The PREP_REAL_CASE exec which generate the MesoNH input files, will take about 4GB of Memory by MPI processes on this grid size, and if mpirun/m(va)pich is detected on the compute node the executable will be run in parallel with 2 MPI processes ( so 4GB*2 = 8GB needed ) . If needed change the MONORUN variable , to run with least memory = 1 MPI processes ( or more processes to run faster if more memory is available )

  • ...
    #export MONORUN="Mpirun -np 2 "
    export MONORUN="Mpirun -np 1 "
    ...


Real MesoNH Drihm Case0 with datarsync-user acces

  • download the mesonh_real_drihm0_datarsync.sh file , (rename it to test.sh if needed ) and run it .

  • Data will be fetch via rsync port 2222 from our MesoNH WEB site <=> 3GB for static PGD files + 1.5 GB for GRIB Time dependent files .

  • /!\ bandwidth problem now fixed about 10MB/sec expected , tell me (Juan) if not the case ...
