Several approaches have been proposed for cosimulation between QEMU and SystemC. On the contrary, no paper addresses integration between Open Virtual Platform (OVP) and SystemC. Indeed, OVP models and the related simulator can be integrated into SystemC designs by using TLM 2.0 wrappers and opportune OVP APIs. However, this solution presents some disadvantages, like the incapability of supporting cycle-accurate models, and the necessity of re-design, in terms of SystemC modules, all OVP components that should be integrated in the target platform. To avoid such drawbacks, and provide an easy way to port SystemC models from a QEMU-based to an OVP-based virtual platform and vice versa, this paper presents a common co-simulation approach that works for integrating SystemC components with both QEMU and OVP.

Modern software uses frameworks through their application programming interfaces (APIs). Framework APIs may change while frameworks evolve. Client programs have to upgrade to new releases of frameworks if security vulnerabilities are discovered in the used releases. Patching security vulnerabilities can be delayed by non-security-related API changes when the frameworks used by client programs are not up to date. Keeping frameworks updated can reduce the reaction time to patch security leaks. Client program upgrades are not cost-free, developers need to understand the API usages in client programs and API changes between framework releases before conduct upgrading tasks. In this paper, we propose a tool ACUA to generate reports containing detailed API change and usage information by analyzing the binary code of both frameworks and clients programs written in Java. Developers can use the API change and usage reports generated by ACUA to estimate the work load and decide when to starting upgrading client programs based on the estimation.

This paper presents a solution of integrator application programming interface (API) generator. The goal of the solution is to decrease the integration time required for the TR-069 support in an arbitrary device, by providing an adaptive build system which generates API specific for the target device which is defined by a TR-106 data model specification. Evaluation results indicate that the implemented solution contributes to the decrease of integration time, based on the case of an example practical project in which TR-069 service is provided for an Android-based set-top box device.

This paper presents an implementation of Multicore Communications API (MCAPI), with focus on portability, stability, and simplicity of the design. The main motivation for the implementation is instability of other publicly available implementations. The developed implementation utilizes POSIX message queues, that is an easily portable interface and readily compatible with MCAPI. The performance was measured as latency and transfer rate of the API. The measurement platforms were a x86-64 PC and a development board featuring an ARM processor. A MCAPI implementation was used as reference for comparison. PMQ-MCAPI is much more stable and easily usable than other MCAPI implementations publicly available for PC. When transfer size was between 1-8 KiB, latency of transfers between cores was between 9-15 mu s and transfer rate 500-5000 MBps. This translates to 27 000-45 000 cycles and 0.16-1.67 bytes per cycle. CPU and especially performance of its cache were concluded as the most important factors contributing to the performance. In comparison to the reference, latency of the implementation was 1/8 at best, while transfer rate was up to 35x.

Cloud manufacturing refers to "as a Service" production model that exploits an on-demand access to a distributed pool of diversified manufacturing services and resources. It forms elastic and reconfigurable production lines, which enhance efficiency, by allowing optimal resource allocation in response to demand changes and market dynamics. This paper studies these challenges and proposes a portable cloud manufacturing platform, entitled "CloudMan", aiming at achieving a portable deployment of cloud manufacturing services to any compliant distributed production line in the cloud. The stakeholders of CloudMan are detailed together with their API requirements, where each stakeholder has an interest in. Having this rigorous analysis in mind, we present a holistic architecture for CloudMan, as it considers the manufacturing data, material and event flow from sensors and shop floors, through services to end products. In architecting such platform, there is a lack of agreed standard for the portability and orchestration of manufacturing services, as well as their definition. The proposed platform incorporates OASIS Topology and Orchestration Specification for cloud applications (TOSCA) policies, plans and templates as a mechanism for dynamic configuration, portability and deployment of manufacturing services across multiple collaborating manufacturers. Thereby, the architecture provides a set of abstraction levels for various types of manufacturing services in which encapsulates and addresses specific requirements to satisfy the needs of stakeholders.

This paper presents a case study of the integration of the Long Term Evolution (LTE) physical layer into the radio protocol subsystem of a macrocell base station. We conduct tests in the laboratory using a modular experimental setup aimed at validating this protocol stack integration. Measurements and analysis are carried out with the aid of Wireshark, a well-known protocol analyzer tool. This choice allows the inspection of data packets at the application program interface between PHY and MAC subsystems. Our results suggest that the LTE protocol stack can operate synchronously, thus supporting message sequences conveyed within both random access and radio-resource-control connection procedures. The proposed experimental setup and test methodology make it possible to validate the control plane operation of the protocol stack without the need of a core network interface.

In certain business sectors adapting to modern and cost reducing technologies and service models can be still a challenge. This especially applies for health care related SME, such as hospitals, where cost reduction runs counter the need of being compliant to legal regulations and where the access control has to struggle against a diverse landscape of health care equipment accompanied by dynamic and complex role models. Outsourcing data storage and data processing seems not to reduce the complexity, rather bears the risks of reduced data availability, loss or abuse of data and can increase legal compliance risks and concerns. Since this applies for many SMEs, a common platform, such as an ecosystem, can help to lower the entrance barrier by regaining helpful management functionalities, standardized basic services and therefore push the adoption to modern cost reducing service consumption scenarios. In this paper a generic design pattern for realizing distributed authorization in an API ecosystem is presented. The pattern is applied within a research project, which aims to develop an ecosystem for trading and consuming services within demanding business sectors and reduce lock-in effects for both, service providers and consumers. The concept of Distributed Authorization is applied in a new complex multi entity use-case, where access policies for RESTful APIs can be designed flexible under consideration of service providers' and consumers' requirements which are enforced by a central trusted 3rd party provider.

The power and energy walls are changing the way users utilize supercomputers: Time-to-completion is not the only important goal but other metrics, such as the energy required to solve a problem or the power efficiency, are becoming as important as performance. This shift towards power- and energy-aware computing is expected to continue in the exascale era, thus, understanding the performance, power and energy implications of different hardware configurations is of paramount importance. In this paper we analyze the performance, power efficiency and energy consumption of scientific applications programmed in MPI, OpenMP and MPI+OpenMP on two different architectures that have take different approaches to limit power consumption, IBM POWER7+ and AMD Interlagos. We compare the scalability, power efficiency and energy consumption of distributed and shared memory versions of each applications and analyze performance and bottlenecks of different combinations of MPI tasks/OpenMP threads. Our results show that, although shared memory programming models usually provide lower synchronization cost, achieving the highest performance/efficiency requires a combination for MPI tasks/ OpenMP threads that is dependent on the underlying architecture and takes into consideration how hardware resources are distributed among the computing elements. More importantly, our results show that the "best configuration" strongly depends on the particular target metric.

DATA PUBLISHING AND ARCHAEOLOGY'S INFORMATION ECOSYSTEM

Though archaeologists have long recognized the importance of detailed data documentation, the practical limits of conventional paper publication have usually prevented sharing such information in detail. Researchers have been forced to select what they see as the most important data to disseminate or to provide summarized data tables to support heir arguments. Advances in technology over the past few decades allow researchers to collect even more digital data than ever before. However, dissemination practices have not kept pace with technological advances. Scholars still largely cling to traditional channels for communicating their research. After all, publishing is a high-stakes game in academia. In today's highly competitive pressure cooker, researchers are loath to invest effort in new forms of publishing where recognition and rewards are far from certain.

Whilst robots are increasingly being used in scenarios that involve human-robot interaction, it is still difficult to program them to interact with humans. This is because current programming tools either require programmers to work at low abstraction levels or they lack features needed to implement particular aspects of human-robot interaction. Our goal is to create an API that is both capable of programming a wide range of human-robot interaction scenarios and is easy to use by the various users of human-robot interaction programming tools. We have taken a first step toward this API by developing an exemplar, high level API for programming social interaction and evaluating it with the Cognitive Dimensions framework. We plan to explore other aspects of human-robot interaction, including navigation and manipulation and exploring how they should be integrated with our existing primitives for programming social interaction.
