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...
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...
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...
Two open source distributed machine learning/deep learning platforms, namely H2O and Apache SINGA, compared their deep learning performances using multilayer perceptron on the classic MNIST database for hand written digits recognition. However, the results reported by both parties differ and neither of them can repeat the results reported by the other side. This paper is an independent study of the...
Cloud computing is one of the emerging fields in both the academics and the IT Industry. It offers different service models and provides an on-demand, pay-per-use, multitenant, pervasive model which makes it suitable to adapt in the fast growing industries. But this new technology suffers from some of the security concerns, since our data and computations are handled by third party infrastructure...
Using state of the art design methods, advanced calculation of system power budgets is a major challenge. Currently, system design methods do not offer sufficient means for supporting energy awareness and efficiency throughout the complete system design process. In this paper, we present a power database for storing and predicting power data of integrated systems across abstraction levels, starting...
Multi-tenant applications are usually cloud based software services which can serve different users at the same time. This is done using single instance of applications by sharing hardware, infrastructure, data storage and virtualization. To achieve multi tenancy different approaches are there at every layer (Application, Data, hardware). Software-as-as-Service (SaaS) is a new approach for developing...
One of the scariest aspects of doing business is the failure to come up with the right decision. This is one of the reasons why many businesses have failed because of one small wrong decision. So the aim of this paper is to develop web based business intelligence software as a service to help the enterprise to maximize the profit by analyzing the data and providing detailed graphical view of the business...
Focusing on the development of virtual reality technology and the disadvantage of fixing computer, such as expensive and easy to wear and tear,the project which consists of dynamic web, database and virtual reality is being proposed; furthermore, based on B/S model, computer virtual fixing system will be designed to be available, extensible, and easy to be updated and maintained.
As scientific computing users migrate to petaflop platforms that promise to generate multi-terabyte datasets, there is a growing need in the community to be able to embed sophisticated data analysis algorithms in the storage systems for the computing platforms. Data Warehouse Appliances (DWAs) are an attractive option for this work, due to their ability to process massive datasets efficiently. While...
Optimal multi-threaded database accesses have garnered profound interest from both end-users and scholars in the last several years. After years of confirmed research into database accesses, we show a fast algorithm, which embodies the important principles of complexity theory. Our new approach for multi-threaded database accesses, is the solution to all of these grand challenges.
Hardware-in-the-Loop (HIL) simulation is an important method in the design and validation process of complex hardware/software systems like electronic control units (ECU) for automotive applications. In [1] we presented an approach called Chip Hardware-In-The-Loop Simulation (CHILS) to embed a microcontroller (MC) into different simulation environments. To optimize the coupling between simulation...
Simulation is an important method in the research and development of storage and network system. A good simulator can save memory and times. There are many simulators developed, but most of those simulator aimed at performance and data schedule algorithm. None of those simulators can model manipuility and dependability in large scale storage network. In this paper, we present the facilities and design...
Trusted platform module (TPM) is a key component to trusted computing, which is proposed to improve security on general platforms. Therefore, it's very necessary to test related products. This paper proposes a conformance testing model based on state machine model with related testing strategies and develops an automated testing tool, which can deal with state space explosion and generate test suits...
Computer architecture simulation and modeling require a huge amount of time and resources, not only for the simulation itself but also regarding the configuration and submission procedures. A quite common simulation toolset (SimpleScalar) has been used to model a variety of platforms ranging from simple unpipelined processors to detailed dynamically scheduled microarchitectures with multiple-level...
Probably the single most important concern of the biotechnology industry is to improve existing biotechnology applications and tools due to the exponential increase in the size of the datasets. Improving application specific performance, pertaining to sudden and dynamic changes in the execution environment has been a widely researched problem. This research was undertaken to find application specific...
The complexity of the selection procedure of a genetic algorithm that requires reordering, if we restrict the class of the possible fitness functions to varying fitness functions, is , where is the size of the population. The quantum genetic optimization algorithm (QGOA) exploits the power of quantum computation in order to speed up genetic procedures. In QGOA, the classical fitness evaluation and...
