talk

One of the main objectives of the VERCE project (Virtual Earthquake and Seismology Research Community in Europe) is to provide scientists with a unified, Europe-wide, computing environment able to support data-intensive scientific computation. This talk will be mainly about our approach to designing and building this infrastructure. More specifically, I will present the current computing environment, the rationale for designing our solutions around the workflow paradigm as well as the basic components of the architecture and their interactions. I will conclude with research challenges we have encountered and how we propose to address them in the short- and longer-term.

Data-Intensive Research for Efficiency and Enablement in Heterogeneous Systems

Diversity, in every dimension, is a key attribute of today’s data bonanza. Our research takes a holistic view, embracing this diversity and the consequent intricate interactions between users and systems. We created the Dispel data-streaming language to describe complex computation patterns at high levels of abstraction, while providing meta-information for optimisation. Provenance and contextual information must be harnessed to achieve autonomous execution, data placement, energy efficiency and reliability. Research is needed, that builds foundations for comprehensible and tractable paths through the rapidly evolving data landscape. This must be driven by and tested at realistic scales and diversity levels.

Supporting user communities with customised science gateways – The SCI_BUS project

Rosa.Filgueira — Fri, 01 Feb 2013 09:42:16 +0000

Speaker:

Dr Tamas Kiss,

Grids and clouds are providing robust infrastructures for scientific applications. However, the wider take-up of these technologies have been limited for a long time due to the lack of user friendly interfaces that enable e-scientists to get transparent access to these platforms.
Science gateways are frameworks (or toolsets) which incorporate applications, data and tools to enable running applications on Distributed Computing Infrastructures (DCIs) in a user friendly and intuitive way.

The European SCI-BUS (SCIentific gateway Based User Support) project designs and implements a framework that contains a gateway technology (or toolset) and a customization methodology to support end-users running their applications on DCIs in a seamless way. The gateways, based on widely used production quality frameworks and solutions (Liferay and WS-PGRADE), provide access to a wide range of DCIs incorporating clouds and desktop and
service grid systems. The project not only targets e-scientists, but citizens and businesses as end-users too.

Two different types of gateways are being developed for wide ranges of disciplines. Genericpurpose gateways offer generic services for small communities and a small number of users who do not have the resources to tailor gateways to their own specific requirements.
Customized (or application-specific) gateways are tailored to the specific needs of particular medium- or large-sized communities to provide access to resources and services.

The presentation will provide an overview of the gateway technology and customization methodology developed by the SCI-BUS project, and will demonstrate how a diverse set of user communities can gain access to robust grid and cloud based resources via these gateways.
The WS-PGRADE gateway framework will be introduced with examples for application specific gateways from various disciplines. Special emphasis will be put to earth sciences and seismology, and it will be demonstrated how the South-East European Statistical Seismology community has built a custom gateway utilising this technology.
