class accasim.base.resource_manager_class.ResourceManager(_resource)[source]¶

Bases: object

allocate_event(event, node_names)[source]¶

Method for job allocation. It uses the event request to determine the resources to be allocated.

Parameters:	event – Job event object. node_names – List of nodes where the job will be allocated.
Returns:	Tuple: First element True if the event was allocated, False otherwise. Second element a message.

availability()[source]¶

Returns:	Return system availability

get_nodes()[source]¶

Returns:	Return node names

get_total_resources(*args)[source]¶

Return the total system resource for the required argument. The resource have to exist in the system. If no arguments is proportioned all resources are returned.

Parameters:	*args – Depends on the system configuration. But at least it must have (‘core’, ‘mem’) resources.
Returns:	Dictionary of the resources and its values.

groups_available_resource(_key=None)[source]¶

Parameters:	_key – None for values of all types for all groups. Giving a specific key will return the resource for the specific type
Returns:	Dictionary of {group{type: value}}

node_names()[source]¶

Returns:	Return node names

node_resources(*args)[source]¶

Parameters:	*args – list of node names

Print nodes and its resources

remove_event(id)[source]¶

Method for job release. It release the allocated resources on the specific nodes.

Parameters:	id – Job Id

resource_types()[source]¶

Returns:	Return resource types of the system

system_capacity(type)[source]¶

Parameters:	type – ‘total’ to return the total per resource type ‘nodes’ to return the capacity of nodes
Returns:	Return system capacity

system_resources()[source]¶

class accasim.base.resource_manager_class.Resources(groups, resources, **kwargs)[source]¶

Bases: object

resources class: Stablish the resources, allocate and release their use.

OFF = 0¶

ON = 1¶

allocate(node_name, **kwargs)[source]¶

Method for job allocation. It receives the node name and the resources to be used.

Parameters:	node_name – Name of the node to be updated. **kwargs – Dictionary of the system resources and its values to be used.

availability()[source]¶

System availablity calculation

Returns:	Return a dictionary with the system availability. In terms of {node: {resource: value}}

available_resource_key(_key)[source]¶

Generate the resource key names

Parameters:	_key – Name of the resource
Returns:	Return the Resource key name.

define_group(_groups, name, group)[source]¶

Internal method for defining groups of resources.

Parameters:	name – Name of the group group – Values of the group. As defined in the system config.

release(node_name, **kwargs)[source]¶

Method for allocation release. It receives the node name and the resources to be released.

Parameters:	node_name – Name of the node to be updated. **kwargs – Dictionary of the system resources and its values to be released.

resource_manager()[source]¶

Instantiation of the resource manager object

Returns:	Resource manager object.

system_capacity(type='total')[source]¶

Parameters:	type – ‘total’ to return the total per resource type ‘nodes’ to return the capacity of nodes
Returns:	Return system capacity
