Implementations of Urgent Computing on Production HPC Systems

AbstractThe requirements of urgent computing applications distinguish those applications from other jobs running within a production batch system. To accomodate urgent computing, specific strategies may be used to allow fast job start time, while mitigating adverse effects on the other parts of the workload. San Diego Supercomputer Center (SDSC) has provided high-performance computing resources in a production-oriented environment to urgent computing appli-cations using several techniques. Processing of data, triggered by real-world disaster events has been accomplished. An on-demand reservation capability to support urgent computing applications has been developed and is currently available on the SDSC Trestles machine
