1. A method comprising:

  • obtaining a range list of available timeframes for each job in a list of jobs to consume compute resources in a compute environment;

    converting each availability timeframe in the range list of available timeframes to a first start range;

    determining a second start range based on a node range that indicates available compute resources associated with a node in the compute environment;

    logically AND'"'"'ing the second start range with the node range to yield a second node range;

    logically OR'"'"'ing the second node range with a global node range to yield a third node range, wherein the global node range reflects timeframes and resources available to all jobs that can simultaneously consume resources on a same set of allocated resources;

    generating a list of compute resources based on the third node range on which to start jobs from the list of jobs to consume compute resources and a timeframe at which to start the jobs; and

    establishing a reservation in the compute environment according to the list of compute resources.
