The increasing complexity of available infrastructures (hierarchical, parallel, distributed, etc.) with specific features (caches, hyper-threading, dual core, etc.) makes it extremely difficult to build analytical models that allow for a satisfying prediction. Hence, it raises the question on how to validate algorithms and software systems if a realistic analytic study is not possible. As for many other sciences, the one answer is experimental validation. However, such experimentations rely on the availability of an instrument able to validate every level of the software stack and offering different hardware and software facilities about compute, storage, and network resources. Almost ten years after its premises, the Grid'5000 testbed has become one of the most complete testbed for designing or evaluating large-scale distributed systems. Initially dedicated to the study of large HPC facilities, Grid’5000 has evolved in order to address wider concerns related to Desktop Computing, the Internet of Services and more recently the Cloud Computing paradigm. We now target new processors features such as hyperthreading, turbo boost, and power management or large applications managing big data. In this keynote we will both address the issue of experiments in HPC and computer science and the design and usage of the Grid'5000 platform for various kind of applications.

Cloud is a complex distributed environment which has occupied the center stage in the modern-day service computing; allowing permissive resource provisioning with minimalistic conflict and enabling on-demand, pay-per-use benefits. Provisioning of resources in a dynamic environment, such that none are under-provisioned or over-provisioned is a primal challenge. The problem is analysed, and an optimal resource allocation strategy is formulated by the quantitative analysis of a biologically inspired model called Lotka-Volterra.

An elastic data stream processing system is able to handle changes in workload by dynamically scaling out and scaling in. This allows for handling of unexpected load spikes without the need for constant overprovisioning. One of the major challenges for an elastic system is to find the right point in time to scale in or to scale out. Finding such a point is difficult as it depends on constantly changing workload and system characteristics. In this paper we investigate the application of different auto-scaling techniques for solving this problem. Specifically: (1) we formulate basic requirements for an autoscaling technique used in an elastic data stream processing system, (2) we use the formulated requirements to select the best auto scaling techniques, and (3) we perform evaluation of the selected auto scaling techniques using the real world data. Our experiments show that the auto scaling techniques used in existing elastic data stream processing systems are performing worse than the strategies used in our work.

In Ad hoc Network of Nanosensors for Wastage detection, clustering assist in nodal communication and in organization of the data fetched by the nanosensors in the network. The attempt of traditional cluster formation techniques degraded the formation of cluster in a precise manner. The data from the nanosensors which act as the nodes of the network have to be distinctively added into the clusters. The dynamic path selection cluster would achieve this distinct addition by dynamically creating a path to the data as an initial process and then redirecting the data to their appropriate cluster based to the readied scheme.

In this paper, Viterbi algorithm based on a hidden Markov model is applied to recognize activity sequences from observed sensors events. Alternative features selections of time feature values of sensors events and activity length size feature values are tested, respectively, and then the results of activity sequences recognition performances of Viterbi algorithm are evaluated. The results show that the selection of larger time feature values of sensor events and/or smaller activity length size feature values will generate relatively better results on the activity sequences recognition performances.

In wireless sensor network, energy efficiency is a major concern as the sensors have minimum energy capacity. As the sensor energy consumption plays a vital role in determining the network lifetime, many strategies have been proposed for energy conservation. One of them is mobile data gathering (MDG).In Mobile Data Gathering either the sink can go on tour to collect the data or a Mobile Data Collector (MDC) can collect the data from sensors and drops them back to the static sink. In this paper, static sink with mobile data collector is considered for the topic of interest. The mobile data collector will reach the cluster of sensors at some appropriate locations called as anchor points. For the formation of clusters, many algorithms have been proposed so far, two of them , Square Grid based Clustering (SGC) and Sensor Transmission based Clustering (STC) are analysed here for the selection of anchors in the anchor based mobile data gathering approach

Dubai, often portrayed as a shimmering oasis in the desert, faces its own set of challenges, including the occasional threat of flooding. Despite its reputation for opulence and modernity, the emirate is not immune to the forces of nature. In recent years, Dubai has experienced sporadic but significant floods, testing the resilience of its infrastructure and communities. Among the critical lifelines in this bustling metropolis is the Dubai International Airport, a bustling hub that connects the city to the world. This article explores the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.

Corporate and higher education. Two industries that, in the past, have had a clear divide with very little crossover. The difference in goals, learning styles and objectives paved the way for differing learning technologies platforms to evolve. Now, those stark lines are blurring as both sides are discovering they have content that’s relevant to the other. Join Tammy Rutherford as she walks through the pros and cons of corporate and higher ed collaborating. And the challenges of these different technology platforms working together for a brighter future.
