Pyclaw is a Python-based solver for hyperbolic PDEs that includes the algorithms of Clawpack and SharpClaw.
It has been designed with easy extensibility, performance, and exploration in mind. PyClaw also includes a scalable parallel implementation of Clawpack using PETSc.

You can get the latest development version of PyClaw from http://github.com/clawpack/.
