[Pgi-wg] Definition of a Production Grid

[David Wallom]

I have to firmly disagree. Production should refer to the quality and number
of services that are available rather than its specific size. The scaling of
an infrastructure has nothing at the moment to do with whether its resources
are interoperable. Your separation of large is a completely arbitrary one. A
production grid should be able to display policies and procedures for the
management services and SLDs for the services that it provides users.

Are you suggesting for example that a single national grid is not a
production service? I can assure you for example that GLOW and other
components of OSG as well as the UK NGS etc get an awful lot of work done
with many many publications in high value refereed journals etc. as a direct
result. Maybe we could use publication impact of the work done as a measure
instead, it would be as arbitrary as 'real work'?
