OPTIM 2020 – International Workshop on Optimization of Energy Efficient HPC & Distributed Systems
21 Sep. 2020 (Delayed to 25-29 January 2021)
Barcelona, Spain (virtual)

Energy efficiency optimization has gradually become one fundamental constraint and requisite in the design of High Performance Computing (HPC) and Distributed Systems, comprehending several prominent research domains embracing the processor architectures (homogeneous/heterogeneous many-core GPPs), the processing accelerators and co-processors (e.g., APUs, GPUs, FPGAs, etc.), the distributed infrastructures (clusters, grids, data centers, etc.), the distributed platforms (application models, framework runtimes and virtual machines), and the underlying network and communication subsystem. Moreover, even in the embedded domain, saving energy in battery-supplied devices is established as a fundamental issue in mobile, hand-held and wireless applications and in most pervasive systems.

Accordingly, due to the often imposed thermal, power and energy constraints, an effective minimization and optimization of the energy consumption surpasses the obvious economic impact of the energy cost, since it also directly affects other aspects of the overall infrastructure with a significant influence on its viability, including the power supply and its distribution, cooling mechanisms (cost and space overhead) and management techniques, etc.

These new challenges require innovative and effective solutions to attain an effective optimization and/or minimization of the power consumption in HPC and distributed systems, including energy-efficient architectures, scheduling and mapping algorithms, load-balancing and scalability studies, and communication protocols.

International Conference on Cloud Computing and Services Science (CLOSER 2015)

Workshop on Emerging Software as a Service and Analytics – ESaaSA 2015

Keynote: Economics-inspired Resource and Energy Management for Cloud Environments.

Cloud infrastructures host different kinds of applications belonging to clients with different levels of service agreements. Their execution is supported by high language virtual machines and system-level virtual machines (VMs). Aiming to maximize revenue, by minimizing the operational expenditure, cloud providers often consolidate several VMs in a single server. This is particularly useful also for the emergent distributed clouds where physical resources, at each node, are not so abundant. However, this technique can lead to overcommitment of resources, and to undesirable performance degradation, if carried out in a non-informed way.

Recent work presented proposes new allocation mechanisms for the VMs used by Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS) clouds, and how these mechanisms are to be controlled. They are driven by classic economic notions such as yield, which expresses the return the provider has in applying a given resource allocation to the tenants’ workload, and utility functions, a relation of clients’ perceived usefulness to a given allocation.

For PaaS providers, a Java VM was extended with an integrated resource management API, heap resizing policies for yield maximization and concurrent checkpoint for migration of the execution state. Overall, these new mechanisms impose small penalties, measured in the execution of typical benchmarks, while allowing the use of application-tailored policies.

At the IaaS level, we present a novel cost model and new scheduling algorithms for system-level VMs, along with their implementation in a state-of-the-art cloud simulation framework. Simulations with synthetic and real-world traces, show that the utility-based scheduling allows more VMs to be allocated, thus allowing extra revenue per resource allocated, and shorter waiting times for clients, when comparing with a utility-oblivious redistribution of resources.

Scheduling algorithms are also extended to take into account energy efficiency. For this assessment the typical data center topologies are compared against community networks and community cloud scenarios, which are backed by peer-to-peer architectures.

2nd DataStorm Big Data Summer School
July 2015
Instituto Superior Técnico, UL, Lisboa

Keynote: Big Data Infrastructures: Economics of Resources, Energy, Data, and Applications

Big data processing infrastructures encompass the full spectrum of cloud-based services: ranging from Infrastructure-as-a-Service (IaaS), to Platform-as-a-Service (Paas) and Data-as-a-Service (DaaS) both for storage as well as processing. Our recent work proposes new resource management and task scheduling mechanisms and algorithms, covering IaaS, PaaS, and DaaS. These are driven by economic inspired notions (such as yield, partial-utility and quality-of-data) that express the efficiency and effectiveness of applying resources to the tenants’ workload, taking into account the clients’ and workloads’ perceived usefulness to a given allocation.

At the IaaS level, system virtual machines (VMs), the cloud providers goals are to maximize revenue, by minimizing the operational expenditure, typically through consolidation of several VMs per physical server. We present a novel cost model and new scheduling algorithms for system-level VMs, along with their implementation in a state-of-the-art cloud simulation framework. Simulations with synthetic and real-world traces, show that the utility-based scheduling allows more VMs to be allocated, thus allowing extra revenue per resource allocated, and shorter waiting times for clients, when comparing with a utility-oblivious redistribution of resources. Scheduling algorithms are also extended to take into account energy efficiency. For this assessment the typical data center topologies are compared against community networks and community cloud scenarios, which are backed by peer-to-peer architectures.

Regarding the PaaS level, we propose new resource management and application monitoring mechanisms for the VMs used by Platform-as-a-Service (PaaS). For PaaS providers, a Java VM was extended with an integrated resource management API, heap resizing policies for yield maximization and concurrent checkpoint for migration of the execution state. Overall, these new mechanisms impose small penalties, measured in the execution of typical benchmarks, while allowing the use of application-tailored policies.

Regarding the DaaS level, we address the storage and processing layers, so that the underlying infrastructure and resource management should fit data and application behavior effectively and efficiently. In Big-data noSQL storage, such as HBase, the main requirement is high-availability, but classical consistency models necessarily degrade performance. Still, an important class of applications can tolerate and benefit from relaxed consistency by bounding inconsistent access in application-specific manner. We explore the spectrum between pessimistic and eventual consistency and provide a novel consistency model with Quality-of-Service tailored to geo-replication (Quality-of-Service for Consistency of Data).

In Big-data processing, specifically in Java frameworks such as Hadoop / Map-Reduce and workflows/dataflows of MR jobs, traditional WMS enforce strict temporal synchronization. In continuous processing, resources are wasted due to the small impact that input data often might have on the ?nal output. thus, no data- and application-aware reasoning is performed in order to evaluate impact of new executions on the ?nal data?ow output. This fails at delivering high resource efficiency for long-lasting applications while keeping costs low. We propose a novel dataflow model with Quality-of-Data (QoD) for continuous and incremental processing. The WMS framework enforcing the QoD model trades off results accuracy with resource savings, achieving resource efficiency, controlled performance, and task prioritization, targeting data-intensive data?ows, where processing steps communicate data via a noSQL database.

Invited Talk: Cassowary: Middleware Platform for Context-Aware Smart Buildings with Software-Defined Sensor Networks

Smart devices sense the environment through their sensors and leverage the contextual information derived from the sensor readings to satisfy system requirements such as energy and carbon efficiency and user preferences. Smart buildings compose of smart devices, and local sensors of the devices and device controllers in a coordinated network. Software-Defined Networking (SDN) offers a centralized view of the entire networking data plane elements to a logically centralized controller. While smart buildings and ubiquitous computing are heavily researched, later advancements in networking are not exploited in achieving tenant-aware smart buildings.

Keynote: Conceptual models versus ontologies

The overwhelming use of Internet emphasizes the need for efficient techniques aiming at facilitating the understanding of the information that is found over the Web. This need for understanding is mostly addressed nowadays through the development of ontologies. Still, rather than simply relying on most traditional taxonomic ontologies (e.g. Wordnet), advanced approaches tend to develop to more descriptive ontologies. These are intended to provide agreed descriptions of the data structures representing the complex organization of objects and links of interest within the targeted domain. We are very close here to the goal usually associated with conceptual modeling when in a database environment.
This talk analyzes the requirements for descriptive ontologies, and contrast the requirements to the functionality provided by some current representative approaches that have been proposed for ontology management. Selected approaches originate from research in artificial intelligence, knowledge representation, and database conceptual modeling.

Speaker: Stefano Spaccapietra, EPFL, Switzerland. Stefano Spaccapietra is a honorary professor at EPFL, Switzerland, where he has been heading the database laboratory for over 20 year. He has been in academic positions all along his career. He got his PhD from the University of Paris VI, in 1978, where he first had his master in Computer Science in 1969.
