This is a preliminary design for the PTP Resource Management system. This is the design of the first phase product, which is limited in scope to viewing the state of the resource manager. This includes the machines, jobs, queues, and nodes that are under the resource manager's control. The classes currently in PTP will implement these new interfaces in addition to their previously implemented interfaces.

Package resourcemanager

For interfaces and abstract classes, the responsibilities and collaborations refer to concrete objects that are implementations of the interface or abstract class.

Interface: IRMResourceManager

Responsibilities
Proxy used to connect to the ResourceManagerHost's actual resource manager (ARM).
Retrieve list of machines, nodes, jobs, process, and queues from ARM.
Notify registered objects that the lists have changed, either in composition, or in their element's attributes due to changes propagated from the ARM
Collaborations
IRMResourceManagerHost
IRMResourceManagerListener
IRMResourceManagerEvent
IRMMachine, IRMNode, IRMJob, IRMQueue

Interface: IRMResourceManagerListener

Responsibilities
Registration site for Observer pattern to allow objects to be notified of changes in the IRMResourceManager's status
Collaborations
IRMResourceManager
IRMEvent

Interface: ResourceManagerEvent

Responsibilities
Determine type of changed in the IRMResourceManager's state
Collaborations
none

Class: ResourceManagerHost

Responsibilities
Determine which remote (or local) host's resource manager to proxy
Determine which resource manager on the host to proxy
Collaborations
none

Interface: IRMMachine

Responsibilities
Provide the status information, i.e. attributes, for the ARM's associated machine
Provide specific attributes for a given attribute description
List all nodes associated with ARM's machine
Collaborations
IAttribute
IAttrDesc

Interface: IRMQueue

Responsibilities
Provide the status information, i.e. attributes, for the ARM's associated queue
Provide specific attributes for a given attribute description
List all nodes that may have jobs dispatched from this queue
Collaborations
IAttribute
IAttrDesc

Interface: IRMNode

Responsibilities
Provide the status information, i.e. attributes, for the ARM's associated node
Provide specific attributes for a given attribute description
List all jobs associated with ARM's node
List all queues that can run jobs on this node
Collaborations
IAttribute
IAttrDesc

Interface: IRMJob

Responsibilities
Provide the status information, i.e. attributes, for the ARM's associated job
Provide specific attributes for a given attribute description
List all processes associated with ARM's job
Collaborations
IAttribute
IAttrDesc

Interface: IRMProcess

Responsibilities
Provide the status information, i.e. attributes, for the ARM's associated process
Provide specific attributes for a given attribute description
Collaborations
IAttribute
IAttrDesc

Interface: IAttribute

  Responsibilities:  Maintain the relationship between an attribute's

value and its description Specifies a strict-weak ordering of itself and other attributes Provide a string representation of the attribute

  Collaborations:    IAttrDesc

Interface: IAttrDesc

  Responsibilities:  Provide a string description of the attribute

Provide a name of the attribute Know the actual type of the attribute Create new attributes of the correct type

  Collaborations:    IAttribute
