Getting PISM sources
The latest "stable" version of PISM is stable0.2.
As PISM is currently under rapid development, we distribute it only as compilable source code.
Check out the source code by subversion from
Gna! (recommended):
svn co http://svn.gna.org/svn/pism/tags/stable0.2 pism0.2
Or download a tarball (if you feel you must; SVN is better!): http://download.gna.org/pism/
User's documentation
- The Installation Manual (updated on March 31, 2009) describes how to download PISM source code and install it and the libraries it needs. Installation of PISM for Debian-based Linux (like Ubuntu) is smoothest, but many other Unix flavors including SUSE, Cray, and Mac OS X have been used with success.
- The User's Manual (updated on March 31, 2009) describes how to run PISM for certain simplified geometry situations and illustrates how PISM's numerical approximations are verified. It also describes how to use PISM as a Greenland ice sheet model or a Ross ice shelf model, with basic publicly-available data.
- Changes (compared to stable0.1) include:
- following Climate and Forecasting metadata conventions version 1.4
- supporting both PETSc 2.3.3 and 3.0
- separation of climate inputs from the ice-dynamics core
- software tests
- installation instructions moved to a separate manual
- SSA can be used as a sliding law
- MISMIP and simplified geometry experiments
- new numerical scheme for temperature and age
- bootstrapping code is much more flexible
- unit conversion with a custom version of UDUNITS-1
- model state snapshots without affecting the time-stepping mechanism
- Support at help@pism-docs.org
Technical documentation
- Reference Manual (PDF; automatically generated from source files by doxygen on March 31, 2009; DRAFT!)
- PISM class, namespace, and source file browser (automatically generated by doxygen on March 31, 2009)
- track changes (commit messages) at cia.vc/stats/project/pism
- Get manuals for your version by
cd doc/ && make
Then view manual.pdf (User's Manual) and refman.pdf (Reference Manual) and doxy/html/index.html (PISM class browser). - PISM is a C++ program which uses the
- PETSc library for parallel numerics
- MPI library for interprocess communication
- NetCDF file format
- A customized version of UDUNITS-1 for unit conversion
- and generates CF-1.4 (Climate and Forecasting version 1.4) compliant NetCDF files
