OpenIFS provides academic and research institutions with an easy-to-use version of the ECMWF IFS (Integrated Forecasting System). OpenIFS provides the forecast capability of IFS (no data assimilation), supporting software and documentation. OpenIFS has a support team at ECMWF for technical assistance but limited resources for detailed scientific assistance.
About OpenIFS provides more information about the model.
How to run openIFS:
First check openifs availability on your platform. Currently openIFS is available on UIO HPC (abel.uio.no) only.
module avail openifs -------------------------------------------------------------------------------- /cluster/etc/modulefiles --------------------------------------------------------------------------------- openifs/38r1v04(default)
If nothing is returned, it is likely openifs is not available. If you think it should, then contact us (drift@uio.no).
To load a given openifs version:
module load openifs/38r1v04
We suggest you specify the version you wish to use to avoid any problems if we install a new default version (as it is important to stick to the very same version for your simulations).
When loading openifs the following environment variables are defined:
- OIFS_CYCLE: ECMWF cycle such as 38r1 (version 38, revision 1)
- OIFS_HOME: directory where openIFS has been installed; this can be used to check openIFS sources
- OIFS_DATA: contains openIFS static input data. Even if you use your own compiled version of openIFS, it is NOT necessary to download these files again.
- OIFS_EXAMPLES: directory where all openIFS examples are stored. If you wish to run one of these examples see our dedicated section on running tutorials.
- OIFS_COMP: compilers used to create openIFS executables. We currently use intel compilers.
- OIFS_BUILD: type of build. It triggers a set of compiler options when building openIFS. Currently set to "opt"
- OIFS_GRIB_API_DIR: GRIB-API version used by openIFS to encode/decode GRIB files
- MARS_LSM_PATH: land sea mask used
- EMOS_VERSION: EMOS version (compiled with GRIB-API support). EMOS is used for interpolation routines.
- EMOS_HOME: directory where EMOS has been installed.
- BUFR_TABLES: bufrtables used for decoding/encoding BUFR (not used in the forecast model)
- CREX_TABLES: crex tables used for encoding/decoding CREX data.
For building openIFS, we use interl compilers:
module list Currently Loaded Modulefiles: 1) use.own 3) openmpi.intel/1.6.1 5) hdf5/1.8.9_intel 7) grib_api/1.12.3 9) udunits/2.2.16 11) intelmpi.intel/4.1.3 2) intel/2011.10 4) python2/2.7.3 6) netcdf.intel/4.2.1.1 8) perlmodules/5.10_2 10) intel/2013.sp1.1 12) openifs/38r1v04
