Methods and apparatus, including computer program products, are provided for transporting processes within a distributed computing system, such as a cluster. In one aspect, the computer-implemented method may receive an event at a first node. The event may correspond to a process instance for handling the received event. The process instance may be transported from a second node to the first node. The process instance may be transported from a persistence when the process instance is inactive and, when the process instance is active, the process instance may be persisted to enable transport to the first node. Related apparatus, systems, methods, and articles are also described.

Performing optimized update operations in in-memory database systems. Update values corresponding to a source table of values stored on an in-memory database are identified by an in-memory database computer system based on information from a computer system implementing a software application. The update values are distributed across a plurality of rows, each row including a plurality of column attributes. At least some column attributes of the plurality of column attributes include values updated relative to corresponding column attributes in the source table of values. A row of the update values is identified. The row includes a plurality of column attributes, each column attribute having a respective value. Each value of each column attribute of the row of the update values is the same as a corresponding value of a corresponding attribute of a corresponding row of the source table is determined. Upon such a determination, a corresponding row of the source table stored on the in-memory database is written into the in-memory database by the in-memory database computer system.

In an example embodiment, a load balancing-capable application container at a first network endpoint comprises an analysis component, a communicator component, and a user application, the user application comprising a first portion containing one or more functions executable by either the first network endpoint or a second network endpoint and a second portion containing one or more functions executable by the first network endpoint but not the second network endpoint. The user application is executed, causing invocation of a first function in the first portion. One or more metrics are obtained from the first network endpoint and the second network endpoint. A real-time aggregate score for the first function is calculated based on the one or more metrics. It is then determined whether to execute the first function on the first network endpoint or the second network endpoint based on a comparison of the real-time aggregate score to a threshold.

Some embodiments provide a non-transitory machine-readable medium that stories a program executable by at least one processing unit of a device. The program classifies several connected devices based on to a history of data transfers among the several connected devices. The program also receives a route request for transmitting a data message from a first device in the several connected devices to a second device in the several connected devices. The program further determines, based on the classification of the several connected devices, a route through the several connected devices that starts at the first device and ends at the second device.

InteGrids vision is to bridge the gap between citizens, technology and the other players of the energy system. The project will demonstrate how DSOs may enable all stakeholders to actively participate in the energy market and distribution grid management and develop and implement new business models, making use of new data management and consumer involvement approaches. Moreover, the consortium will demonstrate scalable and replicable solutions in an integrated environment that enables DSOs to plan and operate the network with a high share of DRES in a stable, secure and economic way, using flexibility inherently offered by specific technologies and by interaction with different stakeholders. To achieve these objectives, a complementary partnership covering the distribution system value chain has been established. The consortium includes three DSOs from different countries and their retailers, innovative ICT companies and equipment manufacturers as well as customers, a start-up in the area of community engagement and excellent R&D institutions. InteGrids concepts and approaches are based on the these two elements: 1. the role of the DSO as system optimiser and as market facilitator and 2. the integration of existing demonstration activities in three different regions allowing to move from single solutions to an integrated management at a higher scale while focusing on the scalability and replicability considering current and evolving market (and regulatory) conditions. The three conceptual pillars proactive operational planning with DER, business models for flexible DER, information exchange between different power system actors offer an opportunity to maximize the economic, societal and environmental gains from the combined integration of DRES and flexible DER. A market hub platform coupled with smart grid functions and innovative business models will open opportunities for new services and an effective roll-out of emerging technologies in the short-term.

The mission of BDVe is to support the Big Data Value PPP in realizing a vibrant data-driven EU economy or said in other words, BDVe will support the implementation of the PPP to be a SUCCESS. Behind that mission, there are multiple goals to achieve, which should be taken into full consideration when defining the directions of the PPP. Some of the most challenging ones are: (1) achieving a more competitive landscape of European Big Data providers, leading to bigger market share; (2) creating the context for a more competitive EU industry (transport, manufacturing, public sector, agrifood, media, energy) in the advent of a data-driven revolution where many traditional players will have to transform their processes and re-think their business if they want to remain completive or in some cases, just to survive-; (3) ensuring the sustainability of the investments and actions triggered by the PPP. BDVe has broken down those high-level goals into 7 major priorities for the project: Being accurately informed about most important facts in Big Data so that we have a solid basis to support the decision-making process in the PPP Supporting the implementation of the Big Data PPP from an operational point of view Developing a vibrant community around the PPP Supporting the development of a European network of infrastructures and centers of excellence around Big Data Setting-up a professional Communications strategy Setting up a framework that supports the acceleration of data-driven businesses, and Ensuring the sustainability of the investments and actions triggered by the PPP. The BDVe consortium includes a set of partners that have shown commitment and dedication to the success of the PPP for several years. They have already invested and they have committed to invest along the coming years. We believe that this CSA cannot be a neutral action that offers operational support without further commitment.

Cosmic shear is the distortion of images of distant galaxies due to weak gravitational lensing by the large-scale structure in the Universe. Such images are coherently deformed by the tidal field of matter inhomogeneities along the line of sight. By measuring galaxy shape correlations, we can study the properties and evolution of structure on large scales as well as the geometry of the Universe. Thus, cosmic shear has become a powerful probe into the nature of dark matter and the origin of the current accelerated expansion of the Universe. Over the last years, cosmic shear has evolved into a reliable and robust cosmological probe, providing measurements of the expansion history of the Universe and the growth of its structure. We review here the principles of weak gravitational lensing and show how cosmic shear is interpreted in a cosmological context. Then we give an overview of weak-lensing measurements, and present the main observational cosmic-shear results since it was discovered 15 years ago, as well as the implications for cosmology. We then conclude with an outlook on the various future surveys and missions, for which cosmic shear is one of the main science drivers, and discuss promising new weak cosmological lensing techniques for future observations. © 2015 IOP Publishing Ltd.
