In the current trend of moving everything into the cloud, cloud-based remote desktops are not an exception. Benchmarking virtual remote desktops for performance optimization is an important task for the successful development and deployment planning of virtual desktop infrastructure (VDI) used to deliver remote desktops. This task is very challenging at cloud scale because of rapid evolution of VDI...
With the ever-increasing trend of migration of applications to the Cloud environment, there is a growing need to thoroughly evaluate quality of the Cloud service itself, before deciding upon a hosting provider. Benchmarking the Cloud services is difficult though, due to the complex nature of the Cloud Computing setup and the diversity of locations, of applications and of their specific service requirements...
Face recognition with still face images has been widely studied, while the research on video-based face recognition is inadequate relatively, especially in terms of benchmark datasets and comparisons. Real-world video-based face recognition applications require techniques for three distinct scenarios: 1) Video-to-Still (V2S); 2) Still-to-Video (S2V); and 3) Video-to-Video (V2V), respectively, taking...
There is a clear advantage to developing automated systems to detect human motion in the field of computer vision for applications associated with healthcare. We have compiled a diverse dataset of clinically-relevant motions using the Microsoft Kinect One sensor and release the dataset to the community as an open source solution for benchmarking detection, quantification and recognition algorithms...
With the number of different cloud providers growing the importance for reliable and up-to-date performance data increases to make qualified decision on what providers to use to carry out different tasks. To cope with this issue, this paper proposes a framework usable for distributed and self-organized continuous benchmarking of hybrid and heterogeneous cloud environments. The framework implements...
Hadoop and Map reduce today are facing huge amounts of data and are moving towards ubiquitous for big data storage and processing. Benchmarking tools available are not capable of analyzing performance of the Hadoop cluster system and are made to either run in a single node system. HiBench is an essential part of Hadoop. It is a comprehensive benchmark suit that consists of a complete deposit of Hadoop...
Security is one of the biggest concerns of database administrators. Most marketed software products announce a variety of features and mechanisms designed to improve security. However, that same variety largely complicates the process of selecting the adequate set of software products (i.e., a software package) for a given installation. In this paper we propose an approach that can be used to fairly...
The performance analysis and validation of distributed real-time systems poses significant challenges due to high accuracy requirements at the measurement tools. A fully synchronized time-scale at ultrafine granularity is not easy to generate. Even though there are several analyzer tools for standard switched Ethernet, these tools cannot be applied in time-triggered networks, since they do not meet...
Evaluating the IP Multimedia Subsystem (IMS) Performance is very important due to the critical role it plays in the Next Generation Network (NGN) of the Fixed and Mobile Networks. This paper proposes three robust and scalable methods that can be used to evaluate the performance, the Compliance of the IMS controllers and benchmark their different vendors. These methods are, Performance Test, FUZZING...
This paper analyses the performance of a decentralized and fault-tolerant software layer for Desktop Grid resources management. The grid middleware under concern is named PastryGrid. Its main design principle is to eliminate the need for a centralized server, therefore to remove the single point of failure and bottleneck of existing Desktop Grids. PastryGrid (based on Pastry) supports the execution...
There are many applications for secure multi-party computation (SMC), but practical adoption is still an issue. One reason is that the business model of the application does not match the system architecture of regular secure computation. An important business model is that of a single service provider dealing with many customers. Applications with this business model are e.g. auctions or benchmarking...
We report on the creation of a database composed of images of Arabic Printed words. The purpose of this database is the large-scale benchmarking of open-vocabulary, multi-font, multi-size and multi-style text recognition systems in Arabic. The challenges that are addressed by the database are in the variability of the sizes, fonts and style used to generate the images. A focus is also given on low-resolution...
The wide adoption of web-based distributed systems and consequently their complexity leads to an increasing demand for performance and QoS testing tools for these systems. Pushing forward open NGN protocols has resulted in a proliferation of benchmarking, interoperability and prototyping tools, yet there is still no solid strategy for integrating these efforts, collecting test information and processing...
Network virtual environments (NVE) are an evolving trend combining millions of users in an interactive community. A distributed NVE platform promises to lower the administration costs and to benefit from research done in the peer-to-peer (p2p) domain. In order to reuse existing mature p2p overlays for NVEs, a comparative evaluation has to be done in the same environment (e.g. resources of peers, peer...
The XML coded information is notorious for its verbosity over the actual effective payload. The solution for reducing the verbosity and the performance cost of XML has been the use of the alternative encoding schemes, other than pure text. The processing of the XML using computing resources sparingly is even more important in embedded, and otherwise restricted environments, when the services of the...
Current advances in processor technology, and the rapid development of high speed networking technology, such as ATM, have made high performance network computing an attractive computing environment for large-scale high performance distributed computing (HPDC) applications. However, due to the communications overhead at the host-network interface, most of the HPDC applications are not getting the...
