OGSA-based Grids"


Hi,

We have just written what I hope will be a productive contribution to
the efforts of this group. It's essentially our experiences implementing
WS-Transfer and using a publicly-available WS-Eventing, and comparing it
to WSRF and WSRF.NET. As we all know, it's a difficult/controversial
subject, but we're hoping we can help the community with a concrete
implementation and evaluation.

Title: Alternative Software Stacks for OGSA-based Grids

Abstract: The Open Grid Services Architecture (OGSA) has been a major
step forward for Grid Computing, but its de facto reliance on the Web
Services Resource Framework (WSRF) and WS-Notification have left some in
the community questioning if the Grid software and protocols have become
too complex.  In this paper, we consider the feasibility of an
"alternative"
software stack, based on WS-Transfer and WS-Eventing. We compare and
evaluate WSRF/WS-Notification vs. WS-Transfer/WS-Eventing, first via a
"hello world" service and then via a more complete Grid scenario for
remote execution called "Grid-in-a-Box". By qualitatively and
quantitatively evaluating each approach, we find that subtle differences
exist (e.g., the naming of resources, the creation of resources) but
they are overwhelmingly equivalent in their functionality and implied
performance. Overall, this paper uniquely shows that there could be
alternative software stacks for OGSA-based Grids.
