High-performance modeling and simulation are playing a driving role in decision making and prediction. For time-critical emergency support applications such as severe weather prediction, flood modeling, and influenza modeling, late results can be useless. Computer models must be run and the data analyzed while their predictions can still be applied. These on-demand large-scale computations can't wait endlessly in a job queue for supercomputer resources to become available. Neither can the community keep multimillion-dollar infrastructures idle until required by urgent computation.A specialized infrastructure is needed to provide computing resources quickly,automatically, and reliably.
