The 7th Workshop on Java Technologies for Real-Time and Embedded Systems

The 7th Workshop on Java Technologies for Real-Time and Embedded SystemsJTRES 2009Universidad Complutense de MadridFacultad de Informatica23-25 September 2009Madrid, Spainhttp://pan.vmars.tuwien.ac.at/jtres2009/Over 90 percent of all microprocessors are now used for real-time andembedded applications, and the behavior of many of these applicationsis constrained by the physical world. Higher-level programminglanguages and middleware are needed to robustly and productivelydesign, implement, compose, integrate, validate, and enforcereal-time constraints along with conventional functional requirementsand reusable components. It is essential that the production ofreal-time embedded systems can take advantage of languages, tools,and methods that enable higher software productivity. The Javaprogramming language has become an attractive choice because of itssafety, productivity, its relatively low maintenance costs, and theavailability of well trained developers.Although it features good software engineering characteristics,standard Java is unsuitable for developing real-time embeddedsystems, mainly due to under-specification of thread scheduling andthe presence of garbage collection. These problems are addressed bythe Real-Time Specification for Java (RTSJ). The intent of thisspecification is the development of real-time applications byproviding several additions such as extending the Java memory modeland providing stronger semantics in thread scheduling.Interest in real-time Java in both the research community andindustry has recently increased significantly, because of itschallenges and its potential impact on the development of embeddedand real-time applications. The goal of the proposed workshop is togather researchers working on real-time and embedded Java to identifythe challenging problems that still need to be solved in order toassure the success of real-time Java as a technology, and to reportresults and experiences gained by researchers.This year following two topics are of special interest:* Open source solutions* Multiprocessor and distributed real-time JavaOpen source software and hardware solutions have received growingattention in recent years; major vendors of Java technology haveadopted the open source development model for some of their products.Open source development benefits from distributed peer review andtransparency and enables easy verification of published results.Access to the source code also stimulates building upon prior work,as it allows to reuse tested and reviewed components.Nowadays, real-time systems demand more functionality than inprevious years. Consequently the execution platforms are oftenmultiprocessors or distributed systems. Although the Real-TimeSpecification for Java has addressed some multiprocessor issues,other issues are still outstanding. Furthermore, defining theappropriate RTSJ abstractions for distributed real-time programmingis still an open topic. One day of the workshop will be designatedfor multiprocessor and distributed systems issues with papers, panelsand invited presentations.Submission RequirementsParticipants are expected to submit a paper of at most 10 pages (ACMConference Format, i.e., two-columns, 10 point font). Accepted paperswill be published in the ACM International Conference ProceedingsSeries via the ACM Digital Library and have to be presented by oneauthor at the JTRES.Papers describing open source projects shall include a descriptionhow to obtain the source and how to run the experiments in theappendix. The source version for the published paper will be hostedat the JTRES web site.Accepted papers will be invited for submission to a special issue ofthe Journal on Concurrency and Computation: Practice and Experience.See http://www.cc-pe.net/journalinfo/Topics of interest to this workshop include, but are not limited to:

  • New real-time programming paradigms and language features

  • Industrial experience and practitioner reports

  • Open source solutions for real-time Java
