Openhub's summary of the PISM project

Published: Nov 26, 2017 by The PISM Authors

We think PISM has pretty-good open-source-software cred. But don’t take our word for it. Here is the automatically-generated nutshell (here, on 4 November 2017) at

In a Nutshell, Parallel Ice Sheet Model (PISM)…

  • has had 6,867 commits made by 21 contributors representing 76,716 lines of code
  • is mostly written in C++ , with a well-commented source code
  • has a well established, mature codebase, maintained by a large development team, with stable Y-O-Y [year-on-year] commits
  • took an estimated 19 years of effort (COCOMO model), starting with its first commit in September, 2006, ending with its most recent commit 2 days ago`

PISM 2.0 is out

PISM developers have been hard at work to bring you a brand new version of PISM, packed with new features. After years of development, PISM finally includes a Blatter solver, warranting a new major version: PISM 2.0.

Version 1.2

We are pleased to announce the release of the Parallel Ice Sheet Model (PISM) v1.2.

MPI-M Hamburg, Germany: open postdoc for coupled atmosphere-ocean-ice sheet model

The Max Planck Institute for Meteorology (MPI-M) contributes to the BMBF project “From the Last Interglacial to the Anthropocene: Modeling a Complete Glacial Cycle” (PalMod,, which aims at simulating the climate from the peak of the last interglacial up to the present using comprehensive Earth System Models. Phase II of this project has an open position Postdoctoral Scientist (W073). The successful candidate will be part of a local team performing and analysing long-term transient simulations covering the last glacial and the transition into the Holocene with an interactively coupled atmosphere-ocean-ice sheet model. Additionally, the candidate will contribute to the continued development of this model. The model system consists of the MPI-Earth system model, the ice sheet model PISM, and the solid-earth model VILMA.
