Supporting Collaborative Scientific Workflow Development:The Dispel Information Registry

Presentation Type: 
talk

Large-scale distributed workflow systems for science are nowadays expected to operate in a consistent, predictable way as well as to promote collaboration between researchers or within groups in a unified way. In this talk we will discuss the VERCE Information Registry, which is designed to provide a consistent view of the VERCE ecosystem for seismology along with related architectural requirements, assumptions and interactions with other components.

The VERCE Architecture for Data-Intensive Seismology

Speaker(s): 
Presentation Type: 
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.

Data-Intensive Research for Efficiency and Enablement in Heterogeneous Systems

Speaker(s): 
Presentation Type: 
poster

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.

Supporting user communities with customised science gateways – The SCI_BUS project

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.

Vacancy at CNRS-INSU (Paris): Scientific Software Research Engineer - VERCE project (Applications by February 10th, 2012)

The Centre National de la Recherche Scientifique – Institut National des Sciences de l’Univers (CNRS-INSU) is looking for a new R&D Scientific Software Research Engineer to assist in the VERCE project (http://www.verce.eu/). Details attached, as well as available from the VERCE website.

Topic of this submission: 

Edinburgh Data Intensive Machine (Phase 1)

The Edinburgh Data-Intensive Machine (EDIM1) is a compute-cluster for data-intensive research and experimentation. The product of a joint collaboration between the School of Informatics and EPCC, funded jointly by EPSRC and the University of Edinburgh, EDIM1 is designed to be more ‘Amdahl- balanced’ than existing data-intensive machines insofar as it offers the greatest possible capacity for applications to benefit from the parallelisation of any components where potential for such exists.

EDIM1

Data-intensive e-Science exploiting the Data Bonanza

Speaker(s): 
Presentation Type: 
invited

The 10-years of the e-Science programme and many earlier years of e-Science have shown the critical importance of digital communication in data-intensive research and in collaboration to bring sufficient expertise to bear on challenges. A review of the 10 years of the e-Science programme shows that the significant positive outcomes are often years after the initial work, even though that led to major breakthroughs and achievements.
