Request for Comments: InterGrid - Peering Architecture for Internetworking Disparate Grids
Dear OGSA Colleagues: (A couple of months ago) We have initiated a new project, called "InterGrid", which aims at developing "Peering Architecture and Policies for Internetworking Disparate Grids". A high level summary of the project is given below: -------------- Summary: Grid computing enables the creation of Cyberinfrastructure for e-Science and e-Business applications. Several nations around the world including Australia have developed their own national Grids based on the notion of virtual organisations. These dispersed Grid initiatives have resulted in islands of Grids without any support for peering arrangements between them. This limitation will impede realisation of full potential of the Grid computing paradigm. This InterGrid project aims to revolutionise Grid computing by investigating and developing (a) architectural principles for interlinking Grids, (b) mechanisms for resource provisioning and allocation within and across Grids and (c) peering policies and algorithms for inter-Grid resource management. --------- As you can see this InterGrid project is highly ambitious, a single research group like ours cannot solve all research challenges. Therefore, we put together a detailed research agenda with the aim of sharing it with international community of researchers interested in pursing this new research area within Grid computing. An article describing InterGrid research agenda can be downloaded from: http://www.gridbus.org/papers/InterGrid.pdf It will be great to hear your comments on the proposed InterGrid research agenda. I would also love to hear from those who are interested in pursuing this line of research with focus on a specific issue/area of your interest.

Interesting. One point of note is that inter-grid peering does not need to be symmetric, though asymmetries could be expected to result in compensatory payments. Another is that I'd be highly surprised if all grids were to allow outside agents as much control as your resource allocation model seems to presume (indeed, this is almost certainly not the case for business grids). You should also be aware that the task of working out where to execute a task and how to actually carry out that execution remains non-trivial in general, as things can really vary a lot more than you'd expect if you'd only previously been exposed to a largely-homogeneous grid like EGEE (e.g. you can't assume everything is either runtime-deployed or pre-existing on the PATH). Overall, I think you've got an interesting project planned, but it is a lot more ambitious than it appears to be. Donal.
