Utility Accrual Real-Time Scheduling: Models and Algorithms
This dissertation first presents an uniprocessor real-time scheduling algorithm called the Generic Benefit Scheduling algorithm (or GBS). GBS solves a previously open real-time scheduling problem: scheduling activities subject to arbitrarily shaped, time/utility function (TUF) time constraints and …

Utility Accrual Real-Time Scheduling Under Variable Cost Functions
We present a utility accrual real-time scheduling algorithm called CIC-VCUA, for tasks whose execution times are functions of their starting times. We model such variable execution times employing variable cost functions (or VCFs). The algorithm considers application activities that are subject to …

On Best-Effort Utility Accrual Real-Time Scheduling on Multiprocessors
We consider the problem of scheduling real-time tasks on a multiprocessor system. Our primary focus is scheduling on multiprocessor systems where the total task utilization demand, U, is greater than m, the number of processors on a multiprocessor system---i.e., the total available processing …

LWFG: A Cache-Aware Multi-core Real-Time Scheduling Algorithm
… thesis, we consider the problem of cache-aware real-time scheduling on multiprocessor systems. One avenue for improving real-time performance on multi-core platforms is task partitioning. Partitioning schemes statically assign tasks to cores, eliminating task migrations and reducing system …

Optimality of Heuristic Schedulers in Utility Accrual Real-time Scheduling Environments
Scheduling decisions in soft real-time environments are based on a utility function. The goal of such schedulers is to use a best-effort approach to maximize the utility function and ensure graceful degradation at overloads. Utility Accrual (UA) schedulers use heuristics to maximize the accrued …

Bus scheduling implementation on the cell processor
Real-time computing is the study of hardware and software systems that are subject to a “real-time constraint” - i.e., strict deadline guarantees. With uncontrollable cache and front side bus, in the modern computer architectures, the estimation of a tight bound, worst case execution time (WCET) is …
