[glue-wg] CPULoad ExecutionEnvironment

[Laurence Field]

Hi Timo,

What role is the person playing in this scenario? Are they system 
administrators who are wanting to know the state of the fabric or are 
they the end user who submitted the job and wish to know the load on the 
machine where their job is running? Or is the use case something else?

The aim of the Glue Schema is to facility interoperation by agreeing on 
an information model between all the players involved.  It is primarily 
aimed at use cases that are common. It is not a complete solution but 
should provide a core that can be extended to meet grid specific use 
cases.  If these use cases turn out to be common these extensions can be 
incorporated into the core.  If there are objects and attributes that 
are important to you which do not map onto the schema, it suggests that 
you will need to make a few grid specific extensions to meet this use 
cases.
