Abstract

Current real-time application systems demand complex functionality and are increasingly coming to be implemented upon multiprocessor platforms, with complex synchronization, data-sharing and parallelism requirements. However, the formal models for representing real-time workloads have traditionally been designed in the context of uniprocessor environments; hence, they are often not able to accurately represent relevant features of multiprocessor realtime systems. Researchers have recently addressed this shortcoming by applying workload models from Divisible Load Theory (DLT) to real-time systems. The resulting theory, referred to as Real-time Divisible Load Theory (RT-DLT), holds great promise for modeling an emergent class of massively parallel real-time workloads. However, the theory needs strong formal foundations before it can be widely used for the design and analysis of real-time systems. In this paper, we briefly describe our current findings on RT-DLT and ongoing research efforts at extending this work to develop such formal foundations. © 2009 IEEE.

Abstract

Recent research in real-time divisible load theory (RT-DLT) has addressed the problem of distributing arbitrarily parallelizable real-time workloads among processors which become available at different instants in the future. Given a real-time job and the times as which the processors become available, we devise exact efficient algorithms to solve two important problems: (i) determine the smallest number of processors needed to complete this job by its deadline; and (ii) given a specific number of processors, determine the earliest completion time for the job on these processors. © 2008 IEEE.

Abstract

We extend the current state of the art in real-time divisible load theory (RT-DLT), by considering the problems of scheduling a real-time divisible job on computing clusters in which different processing nodes have different computing capabilities, as well as different costs associated with executing on them. We seek to minimize the cost of executing a job while also meeting its deadline. © 2011 IEEE.

CFP: SynCoP 2016

Posted on October 24, 2015 ·

====================================================================
Call for papers

SynCoP 2016
3rd International Workshop on the SYNthesis of COmplex Parameters

(ETAPS satellite event)

http://lipn.univ-paris13.fr/SynCoP2016/
====================================================================

SynCoP aims at bringing together researchers working on verification and
parameter synthesis for systems with discrete or continuous parameters, in
which the parameters influence the behavior of the system in ways that are
complex and difficult to predict. Such problems may arise for real-time,
hybrid or probabilistic systems in a large variety of application domains. The
parameters can be continuous (e.g., timing, probabilities, costs) or discrete
(e.g., number of processes). The goal can be to identify suitable parameters
to achieve desired behavior, or to verify the behavior for a given range of
parameter values.

The workshop will take place on Sunday, April 3, 2016, in Eindhoven, The Netherlands, as a
satellite event of ETAPS.

The workshop may be able to (at least partially) support the travel and the
ETAPS workshop registration fees for one or two PhD or Master student(s).
