Birds of a Feather Session: The Challenges of working with Grids for Simulations

Date: Tuesday 20th September 2006, 17:00 - 19:00 Venue: Conference Room 3

Organiser: Sharon Lloyd & Georgios K. Theodoropoulos

Duration: 120 mins

Aim of workshop
The development of complex discrete event simulation applications usually requires collaborative effort from researchers with different domain knowledge and expertise, possibly at different locations. Furthermore, these simulation systems often require huge computing resources and the data sets required by the simulation may also be geographically distributed. While the High Level Architecture (HLA) defines a standard for the construction of large-scale distributed simulations, Grid technologies enable collaboration and the use of distributed computing resources, while also facilitating access to geographically distributed data sets. The aim of the BoF session is to address the research challenges in developing large-scale distributed simulations on the Grid. Challenges to be addressed include:

  • support for collaborative simulation development

  • advanced model and service discovery mechanisms

  • mechanisms for fault-tolerant, coordinated, secured simulation executions

  • resource management, load balancing and migration mechanisms

  • agent-oriented simulation environments
  • web and grid technologies for simulation frameworks

The aims of this workshop are to articulate the challenges of working with grid for simulations, from the fairly simple heart modeling codes as highlighted in Integrative Biology to the complex as described by the Distributed Simulations on the Grid project.
We will present successes of using the grid in the UK as well as the challenges in doing so.
The workshop will allow attendees to discuss challenges and support needs as well as sharing experience of overcoming these challenges. It is expected that we would be able to provide feedback to providers of such infrastructures for future support of those who require facilities for running simulations.

This workshop will be of interest to both those who have experience of developing codes and managing their simulations on a grid as well as those wishing to learn more before embarking on such a challenge.
