WoTUG - The place for concurrent processes

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, Chair of 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.

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.

Native JCSP - the CSP for Java library with a Low-Overhead CSP Kernel

By James Moores

The JCSP library provides a superior framework for building concurrent Java applications. Currently, CSP is a collection of classes that uses the standard Java Threads mechanism to provide low-level facilities such a process scheduling and synchronization. The overheads of using Java Threads can be quite large though, especially for synchronization and context switching. This paper begins by describing various options for increasing performance, and then how the standard Java threads work. The integration of the low-overhead CCSP run-time system into a Linux-based Sun JDK 1.2.1 Java Virtual Machine is then described. This integration provides the low-level support required to dramatically increase the performance of the JCSP library's model of concurrency. The paper then looks at the problem of maintaining backward compatibility by preserving the functionality of the existing threads mechanism on which much legacy code depends. The paper finishes by looking at the performance displayed by the current prototype JVM and contrasting it with the performance of both Green (co-operatively scheduled) and Native (operating-system scheduled) Java Threads.
