Annual Conference: Communicating Process Architectures
Communicating Process Architectures 2018,
the 40th. WoTUG conference on concurrent and parallel systems, takes place from
Sunday August 19th. to Wednesday August 22nd. 2018 and is hosted by
Professor Dr. Rainer Spallek,
VLSI Design, Diagnostics and Architecture
at the Faculty of Computer Science,
Technische Universität Dresden, Germany.
The conference is organised by Dr. Spallek in collboration with Oliver Knodel and Uwe Mielke
and in partnership with 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:
and to stimulate discussion and ideas on the roles concurrency will play in the future:
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, ...);
Of course, neither of the above sets of bullets are exclusive.
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.
A database of papers and presentations from WoTUG conferences is here.
The Abstract below has been randomly selected from this database.
Using Java for Parallel Computing - JCSP versus CTJ
Java provides support for concurrent and parallel programming throughthreads, monitors and its socket and Remote Method Invocation (RMI) classes.However, there have been many concerns expressed about the way in which thissupport is provided, e.g., , citing problems such as improper implementation ofmonitors and difficulty of programming with threads. Hoare’s CommunicatingSequential Processes (CSP)  model fully specifies thread synchronizationand is based on processes, compositions, and channel communication. It provides amathematical notation for describing patterns of communication using algebraicexpressions and contains formal proofs for analyzing, verifying and eliminatingundesirable conditions, such as race hazards, deadlocks, livelock, and starvation.Two independent research efforts provide a CSP based process-oriented designpattern for concurrency implemented in Java: Communicating Sequential Processesfor Java (JCSP)  and Communication Threads in Java (CTJ) . In this paper, wecompare these two packages, looking at the philosophy behind their development,their similarities, their differences, their performance, and their use.
