Effective use of high performance computing is an essential component of the US economy and national defense. Future computing systems leading to exascale will pose new challenges if they are to be used effectively to simulate complex applications that support the national interest. These systems introduce complexity to processor and system design not previously encountered. This effort brings together six leading universities conducting research leading to software that will support a spectrum of multiscale applications. A key component of the effort is to demonstrate the infrastructure required by these emerging architectures on these applications that include:

•  University of Florida: Compressible multiphase turbulence resulting from explosions such as a volcanic eruption.
• University of Illinois: Plasma coupled combustion in ignition of fuel in, for example, automobile engines.
• University of Notre Dame: The impact of shocks on heterogeneous materials.
• Stanford University: The effect of radiation on particle motion in a turbulent airflow in solar thermal receivers with applications in energy production.
• Texas A&M University: Radiation transport in nuclear reactor design and astrophysics.
• University of Utah: The simulation of large clean-coal boilers leading to clean generation of electricity.

This allocation supports development of software tools in the stated areas. This multi-institutional research project will advance effective use of high performance computing for a broad base of important scientific and technological areas.
