3rd International Workshop on Analysis Tools and Methodologies for
Embedded and Real-time Systems (WATERS 2013)
July 9th 2013, Paris, France
In conjunction with ECRTS 2013

In the research area of real-time and embedded systems, the comparison
among results achieved by different research efforts is often very
difficult or even impossible due to the lack of common tools, data
sets or methodologies upon which the comparison is based. For example,
different authors use different algorithms for generating random task
sets, different application traces when simulating dynamic real-time
systems, different simulation engines when simulating scheduling
algorithms. To make the problem worse, different research communities
(e.g., the real-time, networking, storage, parallel and distributed
computing, Service-Oriented, GRID and cloud computing, etc.) often
consider the same or very similar problems and scenarios (e.g.,
performance of multimedia applications) from different but
complementary perspectives, and they use very different abstraction
models and simulation engines, making it very difficult to build an
integrated view and compare approaches among each other.

Research in the field of real-time and embedded systems (and not only)
would greatly benefit from the availability of well-engineered,
possibly open tools, simulation frameworks and data sets which may
constitute a common metrics for evaluating simulation or experimental
results in the area. Also, it would be nice to have a possibly wide
set of reusable data sets or behavioural models coming from realistic
industrial use-cases over which to evaluate the performance of novel
algorithms. Availability of such items would increase the possibility
to compare novel techniques in dealing with problems already tackled
by others from the multifaceted viewpoints of effectiveness, overhead,
performance, applicability, and others.

The ambitious goal of the International Workshop on Analysis Tools and
Methodologies for Embedded and Real-time Systems is to start creating
a common ground and a community to collect methodologies, software
tools, best practices, data sets, application models, benchmarks and
any other way to improve comparability of results in the current
practice of research in real-time and embedded systems. People from
industry are also welcome to contribute with realistic data sets or
methods coming from their own experience, which in the midterm may
serve as benchmarks for assessing RT research efforts.

Often the research literature on real-time and embedded systems
insists in giving importance mostly to task scheduling, neglecting
other practical aspects of the system achitecture that may strongly
impact the performance of distributed real-time applications, such as:
the presence of shared caches and multiple memory controllers and
paths to the main memory in multi-core and multi-processor systems
(and particularly in NUMA architectures); network technologies and
scheduling, beyond the well-known and well-investigated CAN bus, like
point-to-point or standard TCP/IP; disk access and scheduling, along
with the possibility to simulate different existing storage
technologies (e.g., SSD vs traditional HDs) and architectures (e.g.,
NAS). Furthermore, it is often very useful if the simulation accounts
for some critical elements of the run-time environment software
architecture, such as: the device driver architecture of the Operating
System; the presence of hypervisors and various virtualization
technologies, along with their architecture in handling interrupts and
communications; probabilistic models of the impact of factors that may
be outside of the control of the system designer, such as: latency and
bandwidth variability over open TCP/IP networks, such as the Internet,
or over wireless networks; impact of virtualization technologies;
workload fluctuations at run-time; etc.

All of the above factors, and surely many others, have non-negligible
impact on the responsiveness of distributed real-time systems and
applications, and deserve to be accurately modelled and simulated when
evaluating novel mechanisms and comparing approaches among each other,
in order to achieve realistic results.

The focus of the 2013 edition of WATERS is on tools, benchmarks, and
data sets that are useful for a comprehensive analysis and evaluation
of systems where many of the above factors are considered in an
integrated way (e.g., including an integrated view on computing,
networking, and storage aspects).

The workshop seeks original contributions on methods and tools for
real-time and embedded systems analysis, simulation, modelling and
benchmarking. We look for papers describing well-engineered, highly
reusable, possibly open, tools, methodologies, benchmarks and data
sets that can be used by other researchers.

Areas of interest include, but are not limited to:
* Simulation of real-time, distributed and embedded systems
* Simulation of multi-core, many-core and massively parallel and
distributed systems
* Modelling, analysis and simulation of the various components of
the run-time environment, including the Operating System, the
hypervisor, or complex middleware components
* Tools and methodologies for real-time analysis
* Instrumentation, tracing methods and overhead analysis, including
proper accounting of the overheads due to various virtualization
* Power consumption models and experimental data for real-time
power-aware systems
* Simulation, instrumentation and analysis of complex distributed
systems infrastructures such as for Service-Oriented, GRID and
Cloud Computing infrastructures, when supporting real-time and
QoS-aware applications
* Realistic case studies and reusable data sets
* Comparative evaluation of existing algorithms and techniques

Submitted papers should follow the IEEE conference format and should
not exceed 6 pages in length. Papers may be submitted in either PDF or
Postscript format. The papers will be reviewed by the workshop
Program Committee. All accepted papers will be made available to all
participants one week before the workshop so that contributions can be
examined prior to the event. Instructions on how to submit papers
will be available on the workshop website:

If a paper is accepted, at least one author should register for the
workshop following indications sent in the notification of acceptance,
and present the paper at the workshop in person.

The best papers from the workshop will be invited for being submitted
in extended form to a special issue of the Elsevier Journal of Systems
Architecture. The extended papers will undergo a new peer-reviewing

* Submission deadline: April, 26th 2013
* Acceptance notification: May, 24th 2013
* Camera-ready due: June, 14th 2013
