Urgent computing

Urgent computing is prioritized and immediate access on supercomputers and grids for emergency computations such as severe weather prediction during matters of immediate concern.[https://web.archive.org/web/20080228143847/http://spruce.teragrid.org/ Spruce; Special Priority and Urgent Computing Environment]{{unreliable source?|date=August 2023}} spruce.teragrid.org{{cite journal |last1=Beckman |first1=Pete |title=Urgent Computing: Exploring Supercomputing's New Role |journal=CTWatch Quarterly |date=March 2008 |volume=4 |issue=1 |url=https://icl.utk.edu/ctwatch/quarterly/articles/2008/03/urgent-computing-exploring-supercomputings-new-role.html }}

Applications that provide decision makers with information during critical emergencies cannot waste time waiting in job queues and need access to computational resources as soon as possible.{{cite thesis |last1=Cope |first1=Jason M |date=2009 |title=Data management for urgent computing environments |id={{ProQuest|304873520}} |oclc=650213207 }}{{page needed|date=August 2023}} Systems for urgent computing commonly use dedicated resources to ensure immediate and dedicated access to urgent computations. However, recent studies have shown the possibility of using shared resources to make urgent computing more economical.{{Cite journal |title=Preemptive Parallel Job Scheduling for Heterogeneous Systems Supporting Urgent Computing |date=2021 |doi=10.1109/access.2021.3053162 |last1=Agung |first1=Mulya |last2=Watanabe |first2=Yuta |last3=Weber |first3=Henning |last4=Egawa |first4=Ryusuke |last5=Takizawa |first5=Hiroyuki |journal=IEEE Access |volume=9 |pages=17557–17571 |bibcode=2021IEEEA...917557A |doi-access=free }}
