dragon.infrastructure.pool_desc

A class that uniquely defines properties of a managed memory pool for infrastructure communication.

Classes

`PoolDescriptor`	Globally available descriptior of a pool.
`PoolOptions`	Options object for how a Pool is supposed to be created.

class PoolDescriptor

Bases: object

Globally available descriptior of a pool.

Attributes:

m_uidnonnegative int
unique memory pool id

namestr
string indicating pool name that servers as an identifier to query for the pool

sdescbytes-like object
serialized library descriptor

nodenonnegative int
which node this memory pool is associated with

statecls.State enum member
current state of this pool

class State

Bases: Enum

Current state of the pool.

PENDING = 1

ACTIVE = 2

DEAD = 3

__init__(m_uid=0, name='', node=0, state=None, sdesc=''): sdesc - serialized library descriptor

property sdesc: Returns the serialized library descriptor of the pool.

get_sdict()

Collect the entire information of the pool.

Returns:: A dictionary with all key-value pairs of the available description of the pool.
Return type:: Dictionary

classmethod from_sdict(sdict): Returns the descriptor of the memory pool.

class PoolOptions

Bases: object

Options object for how a Pool is supposed to be created.

class Placement

Bases: Enum

Enum for placement strategy of the pool for its creation.

LOCAL = 0

DEFAULT = 1

SPECIFIC = 2

__init__(placement=0, target_node=0, sattr='')

sattr - serialized library attributes

placement - enum for placement strategy

target_node - ignored if placement request isn’t for a specific node

get_sdict()

Collect the different attributes/options of the memory pool.

Returns:: A dictionary with key-value pairs of the pool creation options.
Return type:: Dictionary

static from_sdict(sdict): Returns the options of the memory pool.
