So something along the lines of:
A) need to create a (named) group of tasks
1) group composition needs to be dynamic; ie. we can add/remove member
tasks at any time.
2) a task can only belong to _one_ group at any one time.
3) grouping need not be hierarchical?
B) for each group, we need to set a CAT mask
1) this CAT mask must be dynamic; ie. we can, during the existence of
the group, change the mask at any time.
C) for each group, we need to monitor CQM bits
1) this monitor need not change
Supporting Use-Cases:
A.1: The Job (or VM) can have a dynamic task set
B.1: Dynamic QoS for each Job (or VM) as demand / load changes
Feel free to expand etc..
