GeWWE - A Generic Web-based Workflow Editor

Michelle.Galea — Fri, 26 Jul 2013 14:18:57 +0000

Speaker:

Dr Sandra Gesing

Researchers often need to use workflows that have been developed by other experts in their field to handle specific parts of their work. Sooner or later they find that they want to use workflows from multiple sources that are written in different languages. Enacting multi-lingual workflows (or meta workflows) has been pioneered in a group of European projects. The next step is to be able to change them when they do not do exactly what you want. But that is not easy if you need to learn a different editor for each workflow language. A solution is a workflow editor supporting different workflow languages and easily adaptable for further workflow languages. The generic web-based workflow editor GeWWE addresses this challenge. The talk will go into detail about the underlying concept and a developed prototype.

MoSGrid - Molecular Simulations in a Distributed Environment

Sandra.Gesing — Thu, 27 Jun 2013 11:33:02 +0000

Speaker(s):

Sandra.Gesing

Presentation Type:

talk

Molecular simulations are indispensable methods in areas like material science, structural biology, and drug design. These methods address data-intensive and compute-intensive problems, which demand high-performance computing to allow data analysis in an acceptable time. The project MoSGrid (Molecular Simulation Grid) offers a workflow-enabled grid portal allowing access to molecular simulation tools on distributed resources in an intuitive manner. Users are able to exchange workflows and data via repositories and, thus, to exchange knowledge about the specific application domain. The talk will give an overview on the current MoSGrid portal, the underlying infrastructure, and an outlook on the next steps.

Supporting Collaborative Scientific Workflow Development:The Dispel Information Registry

Iraklis.Klampanos — Fri, 21 Jun 2013 16:35:55 +0000

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.

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.

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. 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.

The SHIWA and ER-flow projects

Michelle.Galea — Tue, 22 Jan 2013 15:20:54 +0000

Speaker:

Michelle Galea, Malcolm Atkinson

A discussion of the SHIWA and ER-flow projects, based on the meeting held with ER-flow project members on Friday 18th January 2013 at the University of Westminster, London.

The SHIWA project was a 3-year EU-funded project that finished in August 2012. Its aim was to develop workflow interoperability technologies, more specifically, to enable e-scientists to run heterogeneous workflows (i.e. workflows created by different workflow systems), separately or combined, from a single platform, and on different distributed computing infrastructures.

ER-Flow is a follow-on project to SHIWA, a support activity aimed at building on the SHIWA technology and expanding the user community. It is EU-funded for 2 years with a completion date of August 2014.

Information Leakage Analysis in Open Multi-agent Systems: A Case Study in Cloud Computing

David.Rodriguez — Wed, 28 Nov 2012 08:09:33 +0000

NeSC Research Seminar Series

Speaker:

Shahriar Bijani

Open Multi-Agent Systems (MAS) have growing popularity and are predicted to have many applications in near future, as large scale distributed systems such as clouds become more widespread. However, A major practical limitation to open MAS is security.
The focus of the talk would be on prevention and detection of information leakage in agent interactions, defined by LCC (Lightweight Coordination Calculus). Language-based security will be briefly introduced and a Security Type System for LCC will be presented. As a case study, information leakage in a cloud computing scenario will be discussed.

Open Knowledge

David.Robertson — Fri, 29 Jun 2012 14:35:17 +0000

OpenKnowledge is a system which allows peers on an arbitrarily large peer-to-peer network to interact productively with one another without any global agreements or pre-run-time knowledge of who to interact with or how interactions will proceed. Any kind of service (including those involving human/environment interaction) can become a peer or else we provide facilities for users to easily create their own peer, by sharing existing code or writing their own.
