--------------------------------------------------------------
Software aging is the progressive degradation of performance and
dependability in computer programs, especially those executing for long
periods of time. This phenomenon has been extensively studied for over 30
years, as it affects many systems, from embedded devices to server software
to critical systems.
Software rejuvenation, i.e., proactive restart of applications
(components/threads/tasks), reboot of VMs or machines, and failover to a
replica are the most prominent approaches to prevent or postpone the
negative effects of software aging. A variety of rejuvenation techniques,
scheduling plans, scopes, and granularities have been proposed for
different application types and platforms.
WoSAR is the premier international venue for discussing the recent advances
and discoveries in the theoretical and practical aspects of software aging
and rejuvenation research. This year, we encourage submissions targeting
interdisciplinary research, in particular those listed in the topics of
interest.
--------------------------------------------------------------
TOPICS OF INTEREST
--------------------------------------------------------------
This call for papers addresses all researchers and
practitioners interested in the performance and dependability degradation
of software systems. Topics addressed in the workshop include, but are not
limited to:
- Progressive degradation of performability / availability / reliability /
scalability / “-ilities” in software systems.
- Online feedback control view of software rejuvenation.
- Modeling and characterization of the software aging phenomenon.
- Design and evaluation of rejuvenation techniques.
- Analysis of aging-related faults/bugs, errors, and failures.
- Software test strategies for detecting aging-related bugs.
- Monitoring, detection, and data analysis of software aging effects (e.g.,
memory leaks, database index fragmentation, unterminated processes/threads,
accrual of round-off errors).
- New classes of software aging effects.
- Software aging and rejuvenation applied to anomaly detection and security
intrusions.
- Software aging and rejuvenation in Big Data and IoT Apps.
- Prognostics and Health Management (PHM) interactions with software aging
and rejuvenation approaches.
- Environment-dependent bugs and their mitigation techniques.
- Metrics for software performance and degradation.
- Fault localization and testing for aging-related bugs.
- Software refactoring for aging-related software problems.
- Clone detection in aging software.
- Machine learning techniques for aging-related bugs.
- Tools for the detection and repair of memory leaks.
- Software aging monitoring and software rejuvenation techniques for
unmanned vehicles like drones or cars.
- Software aging and rejuvenation techniques for humans in safety-critical
environments, like large warehouses.
- Other software-aging-related phenomena, such as the age of information.
- Analytical, empirical, and experimental studies of any of the above
topics.
For all the above topics, WoSAR is a unique forum to discuss the software
aging and rejuvenation impacts on systems from different domains of
applicability, such as:
Cloud computing, Mobile Edge Computing, Fog computing, Mobile, Machine
learning systems, Embedded, Medical, Cyber-physical systems,
Cyber-Security, Industrial control systems such as SCADA, Smart Grids,
Smart Infrastructures, Smart Cities, Transportation, Telecommunication,
Banking, Military, System of systems, Databases, High Performance
Computing, Software Defined Networks, and others.
