This paper presents Safe-ERfair, an efficient resource allocation strategy for handling overloads in real-time ERfair scheduled embedded systems. Each task has an assigned criticality value and consists of a mandatory part and an optional part. The scheduler employs an a priori look-ahead mechanism at the time of arrival of a new job to examine the occurrence of possible overloads during the execution...
Putting the processor into shutdown state when it is idling is one of the primary methodologies towards the reduction of energy consumption in today's systems where leakage power is emerging as a dominant concern. This paper presents ERfair Scheduler with Processor Shutdown (ESPS), a uniprocessor ERfair scheduler that attempts to minimize energy consumption in rate-based periodic real-time task systems...
We have implemented a job scheduling system for massively parallel system with Mpich that supports different scheduling policies for execution of parallel jobs. The system is available on C-DAC HPC cluster Param Padma. It is highly modular scalable and can easily be adapted to variety of other MPP systems. Conventional job scheduler daemons take a part of resources continuously for its own activity...
