Presentations by group members at external events
We regularly present our work at seminars, specific meetings, and national and international conferences.
This presentation presents the first complete, integrated and end-to-end solution for ad hoc cloud computing environments. Ad hoc clouds harvest resources from existing sporadically available, non-exclusive (i.e. primarily used for some other purpose) and unreliable infrastructures. In this presentation we discuss the problems ad hoc cloud computing solves and outline our architecture which is based on BOINC.
This talks identifies the high value to researchers in many disciplines of having web-based graphical editors for scientific workflows and draws attention to two technological transitions: good quality editors can now run in a browser and workflow enactment systems are emerging that manage multiple workflow languages and support multi-lingual workflows.

WORKS 2013: 8th Workshop On Workflows in Support of Large-Scale Science, Denver, Colorado, USA
The presentation was given to the 41st Workshop of the International School of Geophysics, Erice, Italy, "A Roadmap for Earth Science in Europe: The next generation of Geophysical Research Infrastructures". The meeting was organised by EPOS, ORFEUS, COOPEUS and NERA. I was supposed to talk about massive data processing strategies, but as you will see, I saw that many other frequently occurring impediments to success with data were more dominant, so I tried to draw attention to these issues.

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.

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 don’t do exactly what you want. But that is not easy if you need to learn a different editor for each workflow language.
Typical of the digital revolution, seismology is changing rapidly: the number of deployed seismometers grows rapidly, their performance and connectivity improve and seismologists employ data from other sources, such as LIDAR, satellite images and GPS. But their computational behavior is also changing: they used to just focus on earthquakes, today the use all of the continuous waveform. Just what does this mean for the science and the computational infrastructure to support it? The VERCE project is pioneering this approach and will provide examples during the 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.
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.
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.
