/**

* DOC:
|
* The "Coarse" demand power management policy has the following
|
* characteristics:
|
* - When KBase indicates that the GPU will be powered up, but we don't yet
|
* know which Job Chains are to be run:
|
* - Shader Cores are powered up, regardless of whether or not they will be
|
* needed later.
|
* - When KBase indicates that Shader Cores are needed to submit the currently
|
* queued Job Chains:
|
* - Shader Cores are kept powered, regardless of whether or not they will
|
* be needed
|
* - When KBase indicates that the GPU need not be powered:
|
* - The Shader Cores are powered off, and the GPU itself is powered off too.
|
*
|
* @note:
|
* - KBase indicates the GPU will be powered up when it has a User Process that
|
* has just started to submit Job Chains.
|
* - KBase indicates the GPU need not be powered when all the Job Chains from
|
* User Processes have finished, and it is waiting for a User Process to
|
* submit some more Job Chains.
