Urgent computing is a new and evolving field made possible by the improved fidelity and utility of high-performance computing

High-performance computing

High-performance computing uses supercomputers and computer clusters to solve advanced computation problems. Today, computer systems approaching the teraflops-region are counted as HPC-computers.-Overview:...

 to decision making. It refers to the concept of providing prioritized and immediate access on regular Supercomputers and Grids

Grid computing

Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common goal. The grid can be thought of as a distributed system with non-interactive workloads that involve a large number of files...

 for emergency computations such as severe weather prediction during matters of immediate concern. Applications that provide decision makers with information during critical emergencies cannot waste time waiting in the job queues and need access to compute resources

Computational resource

In computational complexity theory, a computational resource is a resource used by some computational models in the solution of computational problems....
