4th Workshop on Performance Analysis of Big data Systems (PABS)

ABSTRACT 
We are seeing exponential growth in data generated from various platforms like social media, multimedia, enterprises, internet of things etc. It is becoming increasingly difficult to manage, analyze, visualize, model, store, search big data systems. 
However, we also witness growth in the complexity, diversity, number of deployments and capabilities of big data processing systems such as Map-Reduce, Spark, HBase, Hive, Cassandra, Big Table, Pregel and Mongo DB. The big data system may use new operating system designs, advanced data processing algorithms, parallelization of application, high performance computing architectures such as GPUs etc. and clusters to improve the performance. Traditional systems are also upgrading themselves to co-locate with popular big data technologies. The workshop on performance analysis of big data systems (PABS) aims at providing a platform for scientific researchers, academicians and practitioners to discuss techniques, models, benchmarks, tools, case studies and experiences while dealing with performance issues in traditional and big data systems. The primary objective is to discuss performance bottlenecks and improvements during big data analysis using different paradigms, architectures and big data technologies. We propose to use this platform as an opportunity to discuss systems, architectures, tools, and optimization algorithms that are 
parallel in nature and hence make use of advancements to improve the system performance. This workshop shall focus on the performance challenges imposed by big data systems and on the different state-of-the-art solutions proposed to overcome these challenges. The accepted papers shall be published in ACM proceedings and digital library.

1st Workshop on Hot Topics in Cloud Computing Performance (HotCloudPerf-2018)

ABSTRACT
Cloud computing is emerging as one of the most profound changes in the way we build and use IT. The use of global services in public clouds is increasing, and the lucrative and rapidly growing global cloud market already supports over 1 million IT-related jobs. However, it is currently challenging to make the IT services offered by public and private clouds performant (in an extended sense) and efficient. Emerging architectures, techniques, and real-world systems include hybrid deployment, serverless operation, everything as a service, complex workflows, auto-scaling and -tiering, etc. It is unclear to which extent traditional performance engineering, software engineering, and system design and analysis tools can help with understanding and engineering these emerging technologies. The community also needs practical tools and powerful methods to address hot topics in cloud computing performance.
Responding to this need, the HotCloudPerf workshop proposes a meeting venue for academics and practitioners, from experts to trainees, in the field of cloud computing performance. The workshop aims to engage this community, and to lead to the development of new methodological aspects for gaining deeper understanding not only of cloud performance, but also of cloud operation and behavior, through diverse quantitative evaluation tools, including benchmarks, metrics, and workload generators. The workshop  focuses on novel cloud properties such as elasticity, performance isolation, dependability, and other non-functional system properties, in addition to classical performance-related metrics such as response time, throughput, scalability, and efficiency.
Each year, the workshop chooses a focus theme to explore; for 2018, the theme is “Performance in the cloud datacenter.” Articles focusing on this topic are particularly encouraged for HotCloudPerf-2018.

The HotCloudPerf workshop is technically sponsored by the Standard Performance Evaluation Corporation (SPEC)’s Research Group (RG), and is organized annually by the RG Cloud Group. HotCloudPerf has emerged from the series of yearly meetings organized by the RG Cloud Group in conjunction with ICPE, since 2013. The RG Cloud Group group is taking a broad approach, relevant for both academia and industry, to cloud benchmarking, quantitative evaluation, and experimental analysis.

Workshop on Challenges in Performance Methods for Software Development (WOSP-C'18)

ABSTRACT

New challenges to assuring software performance arise as new software development methods emerge. In addition to using middleware and database platforms, new applications may be implemented using environments such as Software as a Service (SaaS) and Service-Oriented Architectures, which are also the key for cloud computing performance modelling. The performance characteristics of these services will inevitably influence the performance and scalability of the applications that use them. The use of DevOps means that new components will be introduced to existing systems while they are running. The new components must allow the performance existing components to continue to be met.

In this fourth edition of WOSP-C, we will explore the performance implications of this evolution in architecture and development and their impact on the inclusion and development of performance. We seek to do this by including research and experience papers, vision papers describing new initiatives and ideas, and discussion sessions. Papers describing new projects and approaches are particularly welcome. As implied by the title, the workshop focus is on methods usable anywhere across the life cycle, from requirements to design, testing and evolution of the product. The discussions will attempt to map the future of the field. They may occur in breakout sessions related to topics chosen by the participants. The discussions will be moderated and summaries posted on line for future reference. This is in keeping with the spirit of the first Workshop on Software and Performance, WOSP98, which successfully identified the issues that were current at the time. The acronym WOSP-C reflects this. There will be sessions which combine papers on research/experience/vision with substantial discussion on issues raised by the papers or the attendees. At least a third of the time will be devoted to discussion on identifying the key problems and the most fruitful lines of future research.

7th International Workshop on Load Testing and Benchmarking of Software Systems (LTB 2018)
Important Dates

ABSTRACT
Software systems (e.g., smartphone apps, desktop applications, e-commerce systems, IoT infrastructures, big data systems, and enterprise systems, etc.) have strict requirements on software performance. Failure to meet these requirements will cause customer dissatisfaction and negative news coverage. In addition to conventional functional testing, the performance of these systems must be verified through load testing or benchmarking to ensure quality service. Load testing examines the behavior of a system by simulating hundreds or thousands of users performing tasks at the same time. Benchmarking evaluates a system's performance and allows to optimize system configurations or compare the system with similar systems in the domain.

Load testing and benchmarking software systems are difficult tasks, which requires a great understanding of the system under test and customer behavior. Practitioners face many challenges such as tooling (choosing and implementing the testing tools), environments (software and hardware setup) and time (limited time to design, test, and analyze). This one-day workshop brings together software testing researchers, practitioners and tool developers to discuss the challenges and opportunities of conducting research on load testing and benchmarking software systems.

4th International Workshop on Energy-aware Simulation (ENERGY-SIM’18)

ABSTRACT
 The energy impact of IT infrastructures is a significant resource issue for many organisations. The Natural Resources Defence Council estimates that US data centers alone consumed 91 billion kilowatt-hours of electrical energy in 2013 – enough to power the households of New York twice-over – and this is estimated to grow to 139 billion kilowatt-hours by 2020. However, this is an underestimation as this figure fails to take into account other countries and all other computer usage. There are calls for reducing computer energy consumption to bring it in line with the amount of work being performed – so-called energy proportional computing. In order to achieve this we need to understand both where the energy is being consumed within a system and how modifications to such systems will affect the functionality (such as QoS) and the energy consumption. Monitoring and changing a live system is often not a practical solution. There are cost implications in doing so, and it normally requires significant time in order to fully ascertain the long-term trends. There is also the risk that any changes could lead to detrimental impacts, either in terms of the functionality of the system or in the energy consumed. This can lead to a situation where it is considered too risky to perform anything other than the most minor tweaks to a system. The use of modelling and simulation provides an alternative approach to evaluating where energy is being consumed, and assessing the impact of changes to the system. It also offers the potential for much faster turn-around and feedback, along with the ability to evaluate the impact of many different options simultaneously.

ENERGY-SIM 2018 seeks original work that is focused on addressing new research and development challenges, developing new techniques, and providing case studies, related to energy-aware simulation and modelling.

4th International Workshop on Quality-Aware DevOps (QUDOS 2018)

ABSTRACT

The QUDOS workshop provides a forum for experts from academia and industry to present and discuss novel quality-aware methods, practices and tools for DevOps.

DevOps extends the agile development principles to include the full stack of software services, from design to execution, enabling and promoting collaboration of operations, quality assurance, and development engineers throughout the entire service lifecycle. Ultimately, DevOps is a process that enables faster releases of a better product to the end user. DevOps encompasses a set of values, principles, methods, practices, and tools, to accelerate software delivery to the customer by means of infrastructure as code, continuous integration and deployment, automated testing and monitoring, or new architectural styles such as microservices.

Software engineering research mainly deals with the development aspects of DevOps, focusing on development methods, practices, and tools, leaving the quality assurance aspects of DevOps behind. Even though development practices such as testing (at all levels) are instrumental in producing quality software, they mostly deal with the functional correctness, while quality assurance deals with a more broadly defined concept of quality, of which functional correctness is just one dimension. However, DevOps needs methods and tools that enable systematic assessment, prediction, and management of software quality in other dimensions as well, including performance, reliability, safety, survivability, or cost of ownership.

The QUDOS workshop aims to provide a venue for advances in the state of the art in DevOps quality assurance methods, practices, and tools. To this end, the workshop brings together experts from both academia and industry, working in diverse areas such as quality assurance, testing, performance engineering, agile software engineering, and model-based development, with the goal to identify, define, and disseminate novel quality-aware approaches to DevOps.

QUDOS 2018 is technically sponsored by the Research Group (RG) and the RG DevOps Performance Working Group of the Standard Performance Evaluation Corporation (SPEC RG), and by the consortium of the EU project DICE. The workshop is supported by the IFIP Working Group on Service Oriented Systems, and by the DFG Priority Programme 1593 (SPP1593) “Design For Future - Managed Software Evolution”, funded by the German Research Foundation (DFG).
