Key-value stores (e.g., Memcached) and web servers (e.g., NGINX) are widely used by cloud providers. As interactive services, they have strict service-level objectives, with typical 99th-percentile tail latencies on the order of a few milliseconds. Unlike average latency, tail latency is more sensitive to changes in usage load and traffic patterns, system configurations, and resource availability...
Nowadays multiple bus communication types are comprehensively employed to construct different networks in vehicles information system design. Data interchange among these networks must be conducted through complex communication gateways, which are difficult to test all the features wholly by manual work. MIC and RS422 communication networks are very common in some special vehicles, so in this paper...
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...
HPC interconnect is a very crucial component of any HPC machine. Interconnect performance is one of the contributing factors for overall performance of HPC system. Most popular interface to connect Network Interface Card (NIC) to CPU is PCI express (PCIe). With denser core counts in compute servers and increasingly maturing fabric interconnect speeds, there is need to maximize the packet data movement...
Latency-critical workloads such as web search engines, social networks and finance market applications are sensitive to tail latencies for meeting Service Level Objectives (SLOs). Since unexpected tail latencies are caused by sharing hardware resources with other co-executing workloads, a service provider executes the latency-critical workload alone. Thus, the data center for the latency-critical...
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...
In today's world mankind is creating wonderful and unpredictable milestone day by day, in all the fields whether it is of nanotechnology or mission mars. This is all due to our deep advance knowledge in technology. As our skills and approaches increases in these areas, it will create huge amount of information and data in bulk, which uses more storage capacity than ever. Due to this it also raise...
FPGA-based accelerators are becoming first class citizens in data centers. Adding FPGAs in data centers can lead to higher compute densities with improved energy efficiency for latency critical workloads, such as financial applications. However FPGA deployment in datacenters brings difficulties both to application developers, and cloud providers. Application writers need to deal with the interfacing...
Mobile Broadband (MBB) Networks are evolving at a fast pace, with technology enhancements that promise drastic improvements in capacity, connectivity, coverage, i.e., better performance in general. But how to measure the actual performance of a MBB solution? In this paper, we present our experience in running the simplest of the performance test: "speedtest-like" measurements to estimate...
Driving assistance is becoming an increasingly important matter nowadays, due to the advancements in technology in fields of communication and signal processing. Helping the driver detect and avoid incoming hazards while driving can save lives and decrease road fatalities. For that purpose, this paper describes a hybrid solution based on hardware modules that can be installed on curvy and/or mountainous...
Memory and logic integration on the same chip is becoming increasingly cost effective, creating the opportunity to offload data-intensive functionality to processing units placed inside memory chips. The introduction of memory-side processing units (MPUs) into conventional systems faces virtual memory as the first big showstopper: without efficient hardware support for address translation MPUs have...
Recent advancement in technologies is reshaping our daily lives. The transformation has changed our traditional class rooms to virtual class rooms which enables millions of people to access knowledge at their fingertips. Recently, Thin Client is one of the mostly adopted technologies in higher education. Universities in Saudi Arabia are among the pioneer international universities who embraced Thin...
So far, the identification by means of some hardware devices, to mention RFID, NFC, and recently geolocation beacons, was mainly related to the physical objects, such as material artefacts, places, humans, and animals. However, little attention was paid to the fact the objects are evolving, changing their position, state, capabilities, goals, etc. Such evolution may depend on time, but also a location...
Internet of Thing (IoT) is growing rapidly with more devices connected to the Internet. One emerging group of these is called wearable devices. The wireless technologies used by wearable devices need to consider the long lasting of battery life. Consequently, Bluetooth Low Energy (BLE) has emerged as the wireless technologies for wearable devices due to its features of low power consumption. In this...
In accordance with the resent advancement in Internet of Things (IoT), the needs for IoT experiment platform have been ever increasing. IoT system consists of various technologies such as networking, sensor controller, edge-side computing, server-side big data collections, analysis and their visualizations. An experimental environment that can handle the development and experiments of such an IoT...
The accurate measurement of a server's power consumption when running realistic workloads enables characterization of its energy efficiency and helps to make better provisioning and workload placement decisions. Information on the energy efficiency of a server for a given target workload can greatly influence such decisions and thus the final energy efficiency of a cluster or data center. However,...
Smart Grids have nowadays gained wide diffusion and relevance. Due to the complexity of the grid, many Smart Grids laboratories have emerged over the years to provide partially virtualized environments for testing and co-simulation testbeds for the modern grid. However, the costs for setting-up Smart Grids laboratories are substantial, representing a barrier for newcomers and for educational purposes...
The new AutoSAR adaptive platform makes mixedcritical automotive systems able to adapt at runtime in response to hardware and software failures. However, mapping functions of these adaptive automotive systems to the hardware nodes and reserving their bandwidth are still major challenges. To tackle such major challenges, in this paper, we propose a model-based approach for the automatic identification...
State Islamic University of Syarif Hidayatullah Jakarta as rapid growing university towards world-class university placed in The edge of Jakarta has a data center runs by its unit of organization called Pustipanda (The Center of Information Technology and Database). The team had made observations during the last one year and found that these data center lately had an incident occurred where its hardware...
Failure in cloud system is defined as an even that occurs when the delivered service deviates from the correct intended service. As the cloud computing systems continue to grow in scale and complexity, there is an urgent need for cloud service providers (CSP) to guarantee a reliable on-demand resource to their customers in the presence of faults thereby fulfilling their service level agreement (SLA)...
