Hi Rosario,
first, thanks for your reply.
Yes, I think you are right about the NodeCount.
Do you know (or someone else know) if there is a ER model that need to be followed about the "commun usage record properties"?
Something like this: "ProjectName" can have none or more "JobId" associated with it. A "JobId" is always associated with only one "ProjectName".... and so on?
Or it can be invented it other ways?
Thanks all,
Carlos.

Hi Carlos,
I'm not one of the authors so I might be wrong, but I suppose there is
some inconsistency between Table A-4 and the rest of the document.
What is called "NumNodes" in Table A-4 most probably is the "NodeCount"
described in the Sections 2.23 (on page 15, draft of May 2005) and 10.5
(page 38).
Am I right?
If yes, on page 15 it says:
"... Number of nodes used. A node definition may be dependent on the
architecture, but typically a node is a physical machine. For example a
cluster of 16 physical machines with each machine having one processor
each is a 16 "node" machine, each with one "processor". A 16 processor
SMP machine however, is 1 physical node (machine) with 16 processors. ..."
So immagine one job (one job ID) that runs on a small cluster of 8
dual-processor machines ... you would have 1 job ID, 8 nodes and
16
processors.
Cheers,
Rosario.
