Most systems that support speculative parallelization, like hardware transactional memory (HTM), do not support nested parallelism. This sacrifices substantial parallelism and precludes composing parallel algorithms. And the few HTMs that do support nested parallelism focus on parallelizing at the coarsest (shallowest) levels, incurring large overheads that squander most of their potential. We present...
Recently, the implementation of IoT technology development has been growing rapidly. One of IoT applications is smart home system. In this system, in-home hardwares are connected to the internet. Thus, residents can access them using any internet-connected devices, such as mobile phones. Since the main concern of the IoT system is communication, the design of an efficient and secure communication...
The issues of software and hardware development are considered of data logging into systems of testing complex objects. The describes the architecture of a system for testing complex scientific-technical objects. In the list of original elements of the concept of building highly reliable, fast-reconfigurable interactive test monitoring and control systems: — using of original technology of representation...
The rapid growth of data and high-dependency of industries on using data put lots of focus on the computing facilities. Increasing the efficiency and re-architecting the underlying infrastructure of datacenters, has become a major priority. The total cost of owning and running a datacenter (DC) is affected by many parameters, which until recently were ignored as their impact on the business economy...
System monitoring is an established tool to measure the utilization and health of HPC systems. Usually system monitoring infrastructures make no connection to job information and do not utilize hardware performance monitoring (HPM) data. To increase the efficient use of HPC systems automatic and continuous performance monitoring of jobs is an essential component. It can help to identify pathological...
This paper proposes a novel hybrid transactional memory scheme based on both abort prediction and an adaptive retry policy. First, the proposed scheme can predict not only conflicts between transactions running concurrently, but also the capacity and other aborts of transactions by collecting the information of previously executed transactions. Second, the proposed scheme can provide an adaptive retry...
In this paper, a customized software tool to manage remote access to test equipment is presented. The software tool is developed using LabWindows/CVI and runs on Ethernet over TCP protocol. Ethernet is used as the media for communication and control since a local-area-network (LAN) infrastructure is mostly available in a facility; and almost all commercial-off-the-shelf (COTS) equipment manufacturers...
Relational databases provide a wealth of functionality to a wide range of applications. Yet, there are tasks for which they are less than optimal, for instance when processing becomes more complex (e.g., regular expression evaluation, data analytics) or the data is less structured (e.g., text or long strings). With the increasing amount of user-generated data stored in relational databases, there...
Development of technologies in bioinformatics resulted into many folds growth of biological data that led to the research for accelerated solutions in various domains of computational bioinformatics. String matching is one of the most widely performed tasks at various stages of computational pipeline and it needs an accelerated and reconfigurable methodology for implementation. In this paper we present...
Early design-space evaluation of computer-systems is usually performed using performance models such as detailed simulators, RTL-based models etc. Unfortunately, it is very challenging (often impossible) to run many emerging applications on detailed performance models owing to their complex application software-stacks, significantly long run times, system dependencies and the limited speed/potential...
The integration of Internet of Things (IoT) and Cloud computing has brought the rising of IoT Clouds able to provide different kinds of IoT as a Service solutions consisting of various micro-services deployed in IoT devices (including sensors and actuators) interacting with different Infrastructure, Platform, and Software as Service (i.e., IaaS, PaaS, SaaS) running in the Clouds' data centres. On...
Indoor localisation has the potential to revolutionise the way people navigate indoors, similar to the tremendous impact that GPS has had on outdoor navigation. A number of solutions have been proposed for indoor localisation but most rely on specialised hardware or on the presence of a strong (access point) infrastructure. Many places do not have such infrastructure, thus limiting the use of these...
This paper targeted to reduce the Queue at a billing counter in a shopping complex. The system does the same by displaying the total price of the product kept inside the cart. In this way the customer can directly pay the amount at the billing counter and leave with the commodities he/she has bought. It eliminates the traditional scanning of products at the counter and in turn speeds up the entire...
The Indian ‘smart cities’ have burgeoning population consuming the intelligent systems running over the city infrastructure and services. One critical set of such services is that of the emergency services involving Ambulances, Police and Firefighters. The services provided by these officials are often time critical, which makes their easy and quick availability a must have attribute. This paper proposes...
ICs are subject to many causes of malfunction such as aging or aggressive environment, while avoiding unwanted behavior of critical applications is a key issue. Monitoring is a cornerstone of safety policies, as it supports triggering counter measures on demand. High Level Synthesis (HLS) allows to easily implement applications in hardware, and some HLS compliant solutions have been reported. These...
The complexity of cyber-physical systems (CPSs) poses new challenges in their design, model checking and maintenance. The hardware and software designers are in search, more than ever, for simple and interoperable approaches that render the complexity of CPSs a treatable matter. In this work, database language is suggested as an enabling technology and a lean technique to the purpose. An example with...
This paper presents an innovation in the implementation of RFID in terms of authentication and offline intelligent payment system in public transport, Bus Rapid Transit (BRT), for the academicians. The authentication is conducted using a contactless smart card as an e-ticket as well as an identity card. Contactless smart cards can be obtained through the registration process on the administrator to...
Due to the high cost and high power consumption problem of the present smart home server, we designed and implemented a home server based on embedded system, mainly developed by ARM11 for a hardware platform, Linux system for operating system, SQLite database and BOA server for a software platform. The home server has successfully implemented the network communication, SQLite database peration and...
In contrast to applications relying on specialized and expensive highly-available infrastructure, the basic approach of microservice architectures to achieve fault tolerance – and finally high availability – is to modularize the software system into small, self-contained services that are connected via implementation-independent interfaces. Microservices and all dependencies are deployed into self-contained...
Uptime is very important with any computer system, because a solution which is not available cannot be relied upon to provide accurate information in a timely and routine manner — usually resulting in the loss of time, revenue, or data. Highly-available systems and websites rely on eliminating single points of failure, and on reacting quickly to any network, hardware or software issues which may occur...
