    "abstract": "We report on the development of a computational framework for the parallel,\nmesh-adaptive solution of systems of hyperbolic conservation laws like the\ntime-dependent Euler equations in compressible gas dynamics or\nMagneto-Hydrodynamics (MHD) and similar models in plasma physics. Local mesh\nrefinement is realized by the recursive bisection of grid blocks along each\nspatial dimension, implemented numerical schemes include standard\nfinite-differences as well as shock-capturing central schemes, both in\nconnection with Runge-Kutta type integrators. Parallel execution is achieved\nthrough a configurable hybrid of POSIX-multi-threading and MPI-distribution\nwith dynamic load balancing. One- two- and three-dimensional test computations\nfor the Euler equations have been carried out and show good parallel scaling\nbehavior. The Racoon framework is currently used to study the formation of\nsingularities in plasmas and fluids.",
