    Improving the Performance of Actor Model Runtime Environments on Multicore and Manycore Platforms

    The actor model is present in many systems that demand substantial computing resources which are often provided by multi-core and multiprocessor platforms such as Non-Uniform Memory Access architectures (NUMA) and manycore processors. Yet, no mainstream actor model Runtime Environment (RE) currently in use takes into account the hierarchical memory characteristics...

    A NUMA-Aware Runtime Environment for the Actor Model

    The actor model is present in several mission-critical systems, such as those supporting WhatsApp and Twitter. These systems serve thousands of clients simultaneously, therefore demanding substantial computing resources usually provided by multiprocessor and multicore platforms. Non-Uniform Memory Access (NUMA) architectures account for an important share of these platforms. Yet, little...

    Strategic Innovation Planning and Partnerships: Aligning Market, Products/Services/Processes and Technologies

    There are different tools to support the innovation planning, however, the paradigm of open innovation shows that there is a need to adopt different partners in the development of technology, product, service or process, and many of the proposals in the literature ignore this theme on the innovation process. This...

    Scheduling Workflows in Multi-Cluster Environments

    Scientific applications modeled as workflows can exhibit both task and data parallelism. Scheduling these workflows in a multi-cluster environment is challenging due to the large number of task mapping possibilities. Therefore, several heuristics have been proposed over the last years to address such a problem. A key limitation of existing...

    An Quantitative Analysis of Current Security Concerns and Solutions for Cloud Computing

    The development of cloud computing services is speeding up the rate in which the organizations outsource their computational services or sell their idle computational resources. Even though migrating to the cloud remains a tempting trend from a financial perspective, there are several other aspects that must be taken into account...

    An Implementation of a Transaction Model for Business Process Systems

    Business process systems have received increased attention from research and industry communities specially in order to guarantee transactional properties. Despite the significant efforts in new transactional models and software tools developed, the business processes still offer a scenario with several theoretical and practical challenges. In this paper, the authors present...

    Interaction Protocols for Cross-Organisational Workflows

    Workflow technologies are widely used in industry and commerce to assist in the specification, execution and completion of well defined processes within organizations. As industrial and commercial relations have evolved, based on advances on information and communications technologies, cross-organizational workflow integration has become an important issue. Since organizations can have...

    Energy and Spectral Efficiencies Trade-off with Filter Optimization in Multiple Access Interference-Aware Networks

    In this paper, the authors analyze the optimized deployment of two resources scarcely available in mobile multiple access systems, i.e., spectrum and energy, as well as the impact of filter optimization in the system performance. Taking in perspective the two conflicting metrics, throughput maximization and power consumption minimization, the distributed...

    Web Services Choreographies Adaptation: A Systematic Review

    A service choreography describes the observable behavior of a multi-party collaboration from a global perspective. Unlike service orchestrations, each party involved in the collaboration knows exactly when to execute its operations and with whom to interact in order to achieve the established common goal. In this paper, especially when a...

    From Business Process Model and Notation to Stochastic Automata Network

    The qualitative and quantitative analysis of operational processes recently started to receive special attention with the business process management systems. But the Business Process Model and Notation (BPMN), the standard representation of business processes, is not appropriate to support the analysis phase. Most of the works proposing mappings from BPMN...

    Embedded System for Security Services Integration

    Researches on security systems have focused typically on creating new services or improving the performance and reliability of a single technique, algorithm or mechanism. The approaches that aim some integration among several security mechanisms have usually focused on a specific strategic application, since the systematic approach for integrating security systems...

    The C Compiler Generating a Source File in VHDL for a Dynamic Dataflow Machine Being Executed Direct Into a Hardware

    In order to convert High Level Language (HLL) into hardware, a Control Data-Flow Graph (CDFG) is a fundamental element to be used. Related to this, Dataflow Architecture, can be obtained directly from the CDFG. The ChipCflow project is described as a system to convert HLL into a dynamic dataflow graph...

    A Routing Load Balancing Policy for Grid Computing Environments

    The evolution of computers and networks has motivated the development of high performance systems using the distributed system concepts. Such evolution has motivated the study of load balancing techniques, low latency protocols, operating systems and middlewares. Furthermore, the evolution from distributed systems based on clusters to grid environments has motivated...
