PISM: a Parallel Ice Sheet Model
home page and documentation

Getting PISM sources

As PISM is currently under rapid development, we distribute it only as compilable source code. The latest stable version of PISM is "stable0.2". Check out your copy by subversion:

svn co http://svn.gna.org/svn/pism/tags/stable0.2 pism0.2

PISM stable0.3 will be released March 2010.

User's documentation

• The Installation Manual (updated on September 29, 2009) describes how to install PISM 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) shows how to use PISM generally. It describes an example Greenland ice sheet model and an example Ross ice shelf model, built from publicly-available data.

Technical documentation

• Reference Manual (PDF; automatically generated from source files by doxygen on March 31, 2009; DEPRECATED; the preferred technical docs are in the HTML browser, next)
• PISM class, namespace, and source file browser (automatically generated by doxygen on March 31, 2009)
• PISM is a C++ program which
  • uses the PETSc library for parallel numerics
  • uses the MPI standard for interprocess communication
  • reads and writes NetCDF files
  • automatically converts units by using UDUNITS
  • and generates CF 1.4-compliant NetCDF files
• Changes from stable0.1.
• Some key journal articles on PISM design and applications.

Development of PISM is supported by NASA's Modeling, Analysis, and Prediction (MAP) program (grant #NNX09AJ38G, 2009--2013), and formerly by NASA's Cryospheric Sciences program (grant #NAG5-11371, 2002--2008).
