Sept. 18, 2000, NASA announced solicitations for Round 3 Grand Challenge Investigations in the area of Interoperability and Performance of Applications in Earth, Life, Space and Microgracity Science. NASA Solicitation ,




Gamma Ray bursts (GRBs), discovered accidentally in the late sixties, are flashed of gamma rays occuring for a period ranging from .01 seconds to several hours. Their is no pattern to either time or location in these occurences. Recent obsevations, coordinated among several teams scattered over the world, have revealed GRBs to be outside our galaxy and therefore requiring immense energies, making the sources, whatever they are, the most powerful explosions in the universe.

The purpose of our response to the solicitation was to propose three levels of needs and activities.

  • Radiation-hydrodynamic simulation of GRB expanding fireballs so as to allow observed data.
  • To develop radiation transport models as a tool for theorists.
  • To develop an Iteroperability Based Environment for Adaptive Meshes (IBEAM) framework for the multiple scientific simulation codes.
