Rod, what you say is true but this is a trivial test of interoperability and
has been demonstrated long ago. I thought the Sam-Grid plan was to integrate
EDG job submission components into Sam. Just using GRAM and Condor-G doesn't
go this far. We also have a long-term GridPP objective to have a single UK
grid. That can mean many things but the ability to run an application over
all machines would seem an obvious measure of success.

John,
> to get back into the UK grid. If there are any D0 or CDF
resources out there
There are CDF and dzero resources on the grid but not accessible to the
EDG RB.
They are accessed via CondorG and GRAM after a query to a condor
negotiator to select the resource.
I would say that GRAM and to some extent CondorG are standard
grid tools
for interoperability. Therefore, all resources being accessible to the
EDG RB, i.e.they are EDG CE's, is not a requirement in order to run
across grids.
How to make grids interoperable is a big subject, but the
starting point
for this should be standard grid tools, not requiring that
everything is
an EDG compute element.
Cheers,
Rod.
