Contained here are the software tools developed by the NASA HPCC ESS group at the University of Washington. These tools may be freely obtained (see each tool for details) and used.

For problems, questions and comments concerning this software, please go to our Bugzilla site and submit a bug report for the "hpcc" product.

Also see our NChilada site where we are distributing tools developed in collaboration with the UIUC Parallel Programming Lab for the running, anaylsis and visualization of numerical simulations within a common parallel environment.

• TIPSY: Theoretical Image Processing System

• SMOOTH: Code for calculating mean-field quantities in N-body simulations, for example the density at every particle position.

• SKID: Code to find gravitationally bound groups in N-body simulations.

• FOF: A friends-of-friends group finder for N-body simulations.

• SOF: A spherical overdensity group finder for N-body simulations.

• AFOF: A fast approximate friends-of-friends group finder.

• DIRECT: An O(N^2) direct sum gravity tool, useful for testing other codes and for calculating small N systems. Now supports periodic boundary conditions!

The software shown above is written and maintained by the HPCC Group in the UW Department of Astronomy.

We offer the following pointers to software NOT supported by this group, but written by other participants in this project: Snyder and Lin's ZPL Programming Language Project and Hugh Couchman's Hydra: a parallel adaptive grid code with SPH.
