    • Systems and methods implementing utility-maximized scheduling of time-sensitive tasks in a resource constrained-environment are described herein. Some embodiments include a method for utility-optimized scheduling of computer system tasks performed by a processor of a first computer system that includes determining a time window including a candidate schedule of a new task to be executed on a second computer system, identifying other tasks scheduled to be executed on the second computer system within said time window, and identifying candidate schedules that each specifies the execution times for at least one of the tasks (which include the new task and the other tasks). The method further includes calculating an overall utility for each candidate schedule based upon a task utility calculated for each of the tasks when scheduled according to each corresponding candidate schedule and queuing the new task for execution according to a preferred schedule with the highest overall utility.

    • Systems and methods implementing a demand-driven workload scheduling optimization of shared resources used to execute tasks submitted to a computer system are disclosed. Some embodiments include a method for demand-driven computer system resource optimization that includes receiving a request to execute a task (said request including the task's required execution time and resource requirements), selecting a prospective execution schedule meeting the required execution time and a computer system resource meeting the resource requirement, determining (in response to the request) a task execution price for using the computer system resource according to the prospective execution schedule, and scheduling the task to execute using the computer system resource according to the prospective execution schedule if the price is accepted. The price varies as a function of availability of the computer system resource at times corresponding to the prospective execution schedule, said availability being measured at the time the price is determined.
