The STAR Unified Meta-Scheduler (SUMS)

• It presents itself as an abstract layer on top of “a” batch system : users writes a job description of his “intent” in XML (eXtensible Markup Language ~ upper set of HTML)

  • Job abstraction allows more flexibility
    • Users DO NOT write a shell script and submit
    • User write an XML and % star-submit MyJob.xml % star-submit-template –template MyTemplateJob.xml –entities jobname=test,year=2004
  • Allows to change the computing model without change of user's habits
    • We can change queue systems without having the need for users to change anything !!!
    • Distributed computing is close (actually a reality in STAR)
