Altreonic will present the novel ARRL criterion at the SASSUR (Next Generation of System Assurance Approaches for Safety-Critical Systems) workshop of SAFECOMP2013 on 24th September in Toulouse, France. The paper is co-authored with the Simula Research Lab in Norway (Jose Luis de la Vara) and the University of Antwerp (Vincenzo di Florio).
In summary: ....
Altreonic has recently added new features to its network-centric RTOS that make programming systems with multiple, even heterogeneous processors even easier than before. The new support extend the virtual shared memory and virtual single processor support.
Supports system-wide shared data structures: virtual shared memory model
OpenComRTOS is the unique formally developed RTOS that can program seamlessly even heterogenous systems from a single processor to 1000's of processing nodes. It comes with a visual modeling environment whereby the developer independently specifies his parallel multi-processor target system and application architecture. Tasks and interaction entities can then be transparently mapped to any node in the system, even when the processors are of a different type. With prioritised scheduling and support for distributed priority inheritance, the system remains real time predictable with a typical code size of less than 10 KB per processing node. From v.1.6 of the OpenComRTOS Designer environment on, the developers benefits from a streamlined kernel source code and new features. OpenComRTOS Designer is however a lot more than an RTOS.

Altreonic is pleased to release a new publication in its Gödel Series, entitled: "QoS and Real Time Requirements for Embedded Many- and Multicore Systems". While the first part is mainly a short summary on real-time scheduling, mostly Rate Monotonic Scheduling and Priority Inheritance support, it already establishes the jump to distributed real-time scheduling as supported in OpenComRTOS.
The second part takes a closer look at modern advanced many/multi-core architectures, interrupt latency and inter-core communication measurements and makes the argument that the sharing of the on-chip resources, including the caches, makes it very hard to predict the temporal properties of an application. Rather than rejecting such advanced architectures, the argument is made to adapt the programming model to be able to handle the stochastic spread rather than trying to control it, even if a good design will try to minimise the spread.
Lastly, the bridge is made from Real-Time scheduling towards Quality of Service scheduling of on-chip resources. The connection is made with the specific case of Safety Integrity Levels. Finally, a proposal is made for a new concept that allows to classify components in terms of the assurance they provide for their functional requirements when resources are failing. Under the name ARRL (Assured Reliability and Resilience Level) it provides guidelines for selecting adequate architectures that allow to provide the required services in the presence of several classes of faults. This topic is the subject of on-going and future publications and provides the basis for extensions to the runtime support in OpenComRTOS.

Altreonic presents a working paper entitled:
"A Formalised Real-time Concurrent Programming Model for Scalable Parallel Programming",authors Eric Verhulst, Bernhard H.C. Sputh at the Workshop on High-performance and Real-time Embedded Systems(HiRES 2013) January 23, 2013, Berlin, Germany.
Held in conjunction with the 8th International Conference on High-Performance and Embedded Architectures and Compilers (HiPEAC 2013)
Altreonic will be speaking at a seminar on Functional Safety in the Vehicle Industry organised by Flanders Drive presenting the results of the ASIL (“Automotive Safety Integrity Levels”) project.
The ASIL project created a development methodology for safety-critical systems, applicable to any type of vehicle or machine. Specialists involved will share the in-depth expertise acquired and illustrate this with various actual applications. The ASIL workflow was successfully imported in Altreonic's GoedelWorks portal where users can adapt it to integrate it with their own organisational processes.
The seminar focuses on the main challenges and opportunities associated with the systematic application of functional safety standards in system development and project management in the automotive industry. External experts as well as ASIL members will present relevant topics.
Eric Verhulst, CTO of Altreonic will speak of:
Cross-domain systems and safety engineering: is it feasible?
During the presentation, a new approach for developing composable systems with different SIL levels will be presented. It introduces the notion of ARRL (Assured Reliability and Resilience Level). See attached presentation.
Joseph Kiniry, Professor at the Technical University of Denmark, Copenhagen replied in a lively discussion topic on "GNATprove, integrating theorem provers with software development" in the LinkedIn discussion group "Formal Methods: Specification, Verification, TCG" as follows:
"We find Altreonic's work tremendous. Their pragmatic use of formal methods toward high-end business needs is really a case study in how to do things right and communicate ones results to industry and the academic community. We, too, believe that there is too much emphasis on post-design validation (and, rarely, verification) and believe that a pragmatic correctness-by-construction approach that appreciates and leverages existing quality development practices is the way forward."

SAFECOMP, the 31th International Conference on Computer Safety, Reliability and Security, is an annual event covering new trends, technologies and experiences in the areas of safety, security and reliability of critical computer applications. This year, the key theme will be "Virtually safe -- making system safety traceable".
Altreonic presents its paper "An Unified Meta-Model for Trustworthy Systems Engineering".
Altreonic has been presenting "Transparent Programming of Many/Multi Cores with OpenComRTOS. Comparing Intel 48-core SCC and TI 8-core TMS320C6678" at the Intel MARC symposium in Toulouse on Friday 20st July 2012. The symposium is focused on "bare metal programming" on the Intel experimental 48core SCC chip. In attachment the paper and presentation. For the full program, visit the ONERA website.
