Data is the new natural resource of this century. As data volumes grow and applications aimed at monetizing the data continue to evolve, data processing platforms are expected to meet new scale, performance, reliability and data retention requirements. At the same time, storage hardware continues to improve in performance and price-performance. In this paper, we present TOKVS - Trillion Operation...
Software-Defined Networking (SDN) is a framework conceived to make network infrastructures more programmable and more easily manageable. We explore the integration of the latter in Wireless Mesh Networks (WMNs) through the design of an opportunistic and self-configurable SDN solution. Opportunistic to be able to cope with the intermittent connectivity and network partitioning and merging scenarios...
Scaling web applications such as e-commerce in cloud by adding or removing servers in the system is an important practice to handle workload variations, with the goal of achieving both high quality of service (QoS) and high resource efficiency. Through extensive scaling experiments of an n-tier application benchmark (RUBBoS), we have observed that scaling only hardware resources without appropriate...
In this paper, a hardware resource management method based on virtualized modeling is designed for the problem of difficult hardware resource management in heterogeneous signal processing platform. Firstly, the hardware architecture of heterogeneous signal processing platform is introduced. Secondly, the hardware virtualization modeling method is given. Finally, the model of resource management based...
Mathematical modeling is an important approach for creating a parallel database management system that could efficiently use capabilities, provided by modern heterogeneous computational clusters, equipped with manycore coprocessors or GPUs. To this day, several models heterogeneous computational systems were proposed, but none of them is suited for modeling database processing. In this paper, we address...
Thanks to its 1-cycle lookup performance, the Ternary Content Addressable Memory (TCAM) is considered an essential hardware component for the deployment of high-performance Software-Defined Networks (SDN). Unfortunately, in many network scenarios, TCAMs can quickly fill due to their limited memory size, thus preventing the installation of new flow-rules and leading to inefficient traffic forwarding...
Fault Management (FM) is a cardinal feature in communication networks. One of the most common FM approaches is to use periodic keepalive messages. Hence, switches and routers are required to transmit a large number of FM messages periodically, requiring a hardware-based packet generator that periodically transmits a set of messages that are stored in an expensive on-chip memory. With the rapid growth...
Nowadays, huge amounts of data are produced within shortest time. Especially modern production and measurement systems daily generate a big volume of data, which is growing exponentially. In many cases the challenge is not just obtaining the data, but an appropriate analysis, which is necessary to extract the significant information for enterprises and institutions. The added value of information...
The goal of the paper is in determining the characteristics of relations between security databases (databases of vulnerabilities, attacks, platforms, weaknesses etc.) to apply the ontological approach for construction of a hybrid security repository. The paper analyzes various security data specifications used in databases and interconnections between different data types. On the basis of the outlined...
Due to advances in medicine, the societies have become aging, which leads to the problem of missing teeth. Missing teeth negatively affects not only external appearance but also personal dietary habits. Therefore, it has become an important issue in dentistry to solve the problem of missing teeth. In Taiwan, dental prostheses for missing teeth are produced by dental technicians in dental laboratories...
Parking in modern world is always a subject of concern and isn't a task to be ignored as it was in old days. With modernization and introduction of digital devices, machines have taken a very important and irreplaceable role in human life. Parking nowadays is also done with the help of much advanced and sophisticated systems. The problem with most of these system is that they need a very high capital...
The tourism industry is a fast growing sector in today's world that has penetrated itself in digital domain. Tourists are unable to fetch necessary information that could be required at the time of emergency due to absence or inappropriate mobile network connectivity. Moreover, tourists are often lost and many casualties are recorded because they could not be tracked and help could not reach them...
Accelerating relational databases in general and SQL in particular has become an important topic given thechallenges arising from large data collections and increasinglycomplex workloads. Most existing work, however, has beenfocused on either accelerating a single operator (e.g., a join) orin data reduction along the data path (e.g., from disk to CPU). In this paper we focus instead on the system...
Early design space evaluation of computer systems is usually performed using performance models (e.g., detailed simulators, RTL-based models, etc.). However, it is very challenging (often impossible) to run many emerging applications on detailed performance models owing to their complex software-stacks and long run times. To overcome such challenges in benchmarking these complex applications, we propose...
This paper describes an industrial case study using Atlassian JIRA® and third party plugins for requirements management in the field of transit systems. The solution presented shows efficiency in supporting the management of requirements, traceability and the systems engineering processes globally. After a short description of the technologies in action and a brief overview of the process we targeted,...
In this paper, we introduce SWiF – Simplified Workload-intuitive Framework – a workload-centric, application programming framework designed to simplify the large-scale deployment of FPGAs in end-to-end applications. SWiF can intelligently mediate access to shared resources by orchestrating the distribution and scheduling of tasks across a heterogeneous mix of FPGA and CPU resources in order to improve...
Oracle's Real Application Cluster (RAC) allows multiple database instances to run on different server nodes in a cluster against a shared set of data files. A critical aspect of an Oracle RAC system is that of instance recovery. When a node suffers from a hardware failure, or a database instance suffers from a software failure, instance recovery is performed by a surviving instance to ensure that...
Hardware development is a major driver for the development of data management systems. For example, due to the increased capacity and low cost of main memory, data management systems have shifted from disk-based to in-memory systems [1]. Recently, databases on emerging hardware have gained a lot of attractions in both academia and industry. A significant amount of research has been devoted to the...
General purpose processors have traditionally been favored over application-specific architectures due to the provided flexibility, standardized and simpler programming model, as well as significant reduction in development time. Fueled by the steady advances in transistor scaling, general purpose CPUs satisfied the performance needs of most applications. While CPUs were becoming ubiquitous, advances...
