Native

The following reference provides information about the Dragon Native API. Much of the API is inspired by Python multiprocessing but includes extended functionality, such as support for explicit placement of resources through the dragon.infrastructure.policy.Policy class.

Python Reference

Infrastructure Information

machine

The Dragon native machine interface provides hardware related functionality.

Process Management

process

The Dragon native process object provides process management across one or multiple distributed systems.

ProcessGroup

Object providing API to manage group of Dragon Processes via Dragon Global Services

Synchronization

`barrier`	The Dragon native barrier is an object for parties number of threads.
`event`	The Dragon native event is an object that is used for signaling between threads or processes.
`lock`	The Dragon native lock provides basic synchronization functionality between processes and threads.
`semaphore`	The Dragon native implementation of the classical semaphore synchronization object.

Communication and Shared Data

`queue`	The Dragon native queue provides ordered object communication between processes.
`value`	The Dragon native value is an ctypes object allocated from shared memory.
`array`	The Dragon native array is an ctypes object allocated from shared memory.

Process Pools

`ApplyResult`	Returned by `apply_async` and has `get` method to retrieve result.
`AsyncResult`	alias of `ApplyResult`
`MapResult`
`Pool`	A Dragon native Pool relying on native Process Group and Queues
