held in conjunction with the

ECRTS13: 25th Euromicro International Conference on Real-Time Systems

July 9, 2013, Paris, France




The RTSOPS 2013 program is now available.  The program includes an invited talk by Alix Munier from the University of Paris 6.


New: The RTSOPS 2013 proceedings is now available.


New: Alan Burns was the recipient of an iPad mini for presenting the open problem "Is Audsley's scheme the most expressive optimal priority assignment scheme?" based on votes from RTSOPS '13 participants. This problem was considered to be one that most people were likely to engage in solving among all the problems presented at RTSOPS '13. RTSOPS '13 organizers, Liliana Cucu-Grosjean and Sathish Gopalakrishnan, thank INRIA for their generous support that made this award possible.


 The 4th International Real-Time Scheduling Open Problems Seminar (RTSOPS 2013) provides a venue for the exchange of ideas and the discussion of interesting unsolved problems in real-time scheduling. The format of the seminar encourages interaction between participants and provides ample time for relaxed discussions. The goal of the seminar is to promote a spirit of co-operation and collaboration within the real-time scheduling community.

RTSOPS 2013 is organized around presentation and collaboration sessions. Each presentation session provides the opportunity to hear about a number of unsolved problems in real-time scheduling, highlighted via brief presentations. The following collaboration session gives participants the opportunity to interact in small groups, exchange ideas with the presenters, explore how the problems might be solved, and take the first steps towards a solution.

In addition, authors of open problem submissions from previous years' RTSOPS are invited to submit short status reports on progress made towards a solution to their open problem. This year’s seminar will include a session for presentation of such advances.



Real-time scheduling theory has provided a foundation for understanding and solving resource allocation and scheduling problems in systems that have real-time constraints. New fundamental results are needed to address recent advances and trends in real-time systems design. RTSOPS 2013 encompasses all aspects of real-time scheduling. 


RTSOPS 2013 invites extended abstracts of open problems in areas such as, but not limited to: 


  • Multiprocessor, uniprocessor, and communications scheduling;
  • Mixed-criticality scheduling;
  • New models for real-time systems;
  • Scheduling in cyber-physical systems;
  • Interactions between WCET (worst-case execution time) analysis and scheduling.
