TM is computationally intensive and requires significant processing power to run in a decent amount of time. Have a look at the list of tested platforms to gauge TM performance.
Input and output data can be large and may require dedicated storage:
- Meteo input is about 300 Gb/year for the 1x1 resolution. See the ERA Interim and Operational Data pages for details.
- Inputs for the chemistry amount to 2.3 Gb without counting AR5, GFED3 and EDGAR4 inventories.
- Output size can reach up to 8 Gb/month if you includes time-series output at 3x2 (full chemistry with m7).
TM5 should run under any Linux/Unix (incl. Mac OS X) operating system. The following softwares are required:
- subversion (svn) to checkout the code. Version 1.6 at least.
- GNU make (sometimes installed as gmake,and sometimes as make)
- makedepf90 to build dependencies
- any Fortran 90 or above
It is recommended to have openMP or/and MPI installed, since they will significantly improve the performance of TM.
You also need to have these libraries installed:
HD5 and netCDF4 must be installed with parallel I/O enabled if you want to use "exact" restart files or output time-series. Exact restart files hold data in double precision, while the older restart files (so-called "save files") use single precision.
Met fields are available in both hdf and netcdf formats. To use the later, you must install UDUNITS.
