Annual Conference: Communicating Process Architectures
Communicating Process Architectures 2016,
the 38th. WoTUG conference on concurrent and parallel systems, takes place from
Sunday August 21st. to Wednesday August 24th. 2016 and is hosted by the
Niels Bohr Institute,
University of Copenhagen.
Conference sessions will take place at the
Hans Christian Ørsted Institute, which is located
here.
The evening Fringe sessions will be at the
Caféen Bar,
which is just
a few minutes walk from the Ørsted buildings.
About WoTUG
WoTUG provides a forum for the discussion and promotion of concurrency ideas,
tools and products in computer science.
It organises specialist workshops and annual conferences that address
key concurrency issues at all levels of software and hardware granularity.
WoTUG aims to progress the leading state of the art in:
-
theory (programming models, process algebra, semantics, ...);
-
practice (multicore processors and run-times, clusters, clouds, libraries, languages, verification, model checking, ...);
-
education (at school, undergraduate and postgraduate levels, ...);
-
applications (complex systems, modelling, supercomputing, embedded systems, robotics, games, e-commerce, ...);
and to stimulate discussion and ideas on the roles concurrency will play in the future:
-
for the next generation of scalable computer infrastructure (hard and soft) and application,
where scaling means the ability to ramp up functionality (stay in control as complexity increases)
as well as physical metrics (such as absolute performance and response times);
-
for system integrity (dependability, security, safety, liveness, ...);
-
for making things simple.
Of course, neither of the above sets of bullets are exclusive.

RMoX: A raw-metal occam Experiment
By Christian L. Jacobsen, Frederick R. M. Barnes, Brian Vinter
Operating-systems are the core software component of many modern computersystems, ranging from small specialised embedded systems through to largedistributed operating-systems. This paper presents RMoX: a highly concurrent CSPbasedoperating-system written in occam. The motivation for this stems from theoverwhelming need for reliable, secure and scalable operating-systems. The majorityof operating-systems are written in C, a language that easily offers the level offlexibility required (for example, interfacing with assembly routines). C compilers,however, provide little or no mechanism to guard against race-hazard and aliasing errors,that can lead to catastrophic run-time failure (as well as to more subtle errors,such as security loop-holes). The RMoX operating-system presents a novel approachto operating-system design (although this is not the first CSP-based operating-system).Concurrency is utilised at all levels, resulting in a system design that is well defined,easily understood and scalable. The implementation, using the KRoC extended occam,provides guarantees of freedom from race-hazard and aliasing errors, and makesextensive use of the recently added support for dynamic process creation and channelmobility. Whilst targeted at mainstream computing, the ideas and methods presentedare equally applicable for small-scale embedded systems - where advantage can bemade of the lightweight nature of RMoX (providing fast interrupt responses, for example).
