Distributed management of flexible times schedules

Stephen F. Smith, Anthony Gallagher, Terry Zimmerman
2007 Proceedings of the 6th international joint conference on Autonomous agents and multiagent systems - AAMAS '07  
We describe an agent architecture for solving this problem that couples two basic mechanisms: (1) a "flexible times" representation of the agent's schedule (using a Simple Temporal Network) and (2) an  ...  We consider the problem of managing schedules in an uncertain, distributed environment.  ...  The coupling of incremental scheduling with flexible times scheduling adds additional leverage in an uncertain, multiagent execution environment.  ...

A survey of self-adaptive grids

Daniel Batista, Nelson da Fonseca
2010 IEEE Communications Magazine  
Adaptive scheduling can be used for any type of application, whereas dynamic scheduling is designed for applications with unknown demands.  ...  When a dynamic scheduling approach is employed, the execution time is 300 min; whereas with adaptive scheduling no migration takes place, and the execution time of the application is 358 min.  ...

Chronos: Failure-aware scheduling in shared Hadoop clusters

Orcun Yildiz, Shadi Ibrahim, Tran Anh Phuong, Gabriel Antoniu
2015 2015 IEEE International Conference on Big Data (Big Data)  
Upon failure detection, rather than waiting an uncertain amount of time to get resources for recovery tasks, Chronos leverages a lightweight preemption technique to carefully allocate these resources.  ...  In addition, Chronos considers data locality when scheduling recovery tasks to further improve the performance. We demonstrate the utility of Chronos by combining it with Fifo and Fair schedulers.  ...  freed, an effective preemption mechanism with low overhead and enforcing data-aware execution of recovery tasks.  ...

Robust almost sure stability for uncertain stochastically scheduled anytime controllers

Luca Greco, Daniele Fontanelli, Antonio Bicchi
2008 2008 16th Mediterranean Conference on Control and Automation  
Hence, preemptive scheduling schemes are considered, under which the maximum execution time allowed for control software tasks is not a-priori known.  ...  The execution of the control tasks are driven by the available computational time of an embedded platform under stringent real-time constraints.  ...  Worst-Case Execution Time (WCET) of tasks.  ...

Prediction performance method for dynamic task scheduling, case study: the OLLAF Architecture

Ismail Ktata, Fakhreddine Ghaffari, Bertrand Granado, Mohamed Abid
2010 2010 5th International Design and Test Workshop  
Actual dynamic applications, executed on real-time systems, have the tendency to be built on dynamically reconfigurable hardware devices.  ...  In order to deal with all of the dynamic aspects of such systems, we describe a predictive scheduling allowing an early estimation of our application dynamicity.  ...  After a task's execution and for uncertain parameters, the prediction technique will compute predicted values to be taken for the next execution. Tasks are executed at the earliest possible time.  ...

Scheduling grid tasks under uncertain demands

Daniel M. Batista, André C. Drummond, Nelson L. S. da Fonseca
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
In this paper, a scheduler based on fuzzy optimization is proposed to deal with such uncertainties.  ...  The uncertainty of the demands of grid applications can cause unpredicted performance and, consequently, can make ineffective schedules derived for target demand values.  ...  These schedulers can be executed in parallel to obtain a schedule with the highest possible quality within a time period.  ...
