AHM08/W5: Frontiers of High Performance and Distributed Computing in Computational Science

Chris Higgins: Spatial Data e-Infrastructure SEE-GEO


What can GRID offer for scaleability of EDINA's services?

Grid was right from the outset interested in security and trans organisational issues. so what does grid offer to SDI that contributes to SDI and its scaleability.

Registries for publish, find and bind fundamental

Demonstrators produced were:

e-Social Science exemplars built:

dont hold hold the data instead link & bind to it and use it from source.
OGC services wrapped into OGSA-DAI

focusing on adding security - using SPAM-GP .. Security Portlets simplifying Access to and Managing Grid Portlets

.but not planning to give security control to portal provider therefore need finer grain security

as a result of project an agreement between OGC and www.opengeospatial.org/ in terms of on-going memorandum of understanding.

Owain Kenway: Distributed Computing using HARC & MPIg

HARC
High Available Resource co-Allocator - HARC proved to be very reliable

MPIg
globus implementation of MPI that allows topology discovery, so that it know what protocols are available for communication between ant two nodes in a multy-distributed cluster architecture.

Approach used for three different applications, two of which benefited very well over distributed sites vs expanded resource at a single resource, and the third, also benefited though not as significantly.
