[ur-wg] some doubts about the UR-Spec

[Rosario Michael Piro]

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.
