Urgent computing is a new and evolving field made possible by the improved fidelity and utility of high-performance computing to decision making[1]. It refers to the concept of providing prioritized and immediate access on regular Supercomputers and Grids for emergency computations such as severe weather prediction during matters of immediate concern[2]. Applications that provide decision makers with information during critical emergencies cannot waste time waiting in the job queues and need access to compute resources as soon as possible[3].
