Accelerator Requests
|
||
++++++++++++++++++++
|
||
|
||
Lists, creates, shows details for, updates and deletes accelerator requests.
|
||
|
||
An accelerator request (ARQ) represents a request for a single accelerator
|
||
to be assigned to an instance. ARQs are created in accordance with the
|
||
resource_groups defined in a `device_profile
|
||
<http://specs.openstack.org/openstack/cyborg-specs/specs/train/implemented/device-profiles.html>`_
|
||
by the operator. The accelerator request in the user request may have N
|
||
request groups, each asking for M accelerators; then N * M ARQs will be
|
||
created for that accelerator request.
|
||
|
||
List Accelerator Requests
|
||
-------------------------
|
||
|
||
.. rest_method:: GET /v2/accelerator_requests
|
||
|
||
Lists host_name, device_rp_uuid, instance_uuid and device_profile_group_id
|
||
for all accelerator_requests.
|
||
|
||
**Example response: list all accelerator requests**
|
||
|
||
.. literalinclude:: ../../doc/api_samples/accelerator_requests/accelerator_requests-list-resp.json
|
||
:language: javascript
|
||
|
||
Get One Accelerator Request
|
||
---------------------------
|
||
|
||
.. rest_method:: GET /v2/accelerator_requests/{accelerator_request_uuid}
|
||
|
||
Gets host_name, device’s_RP_UUID, instance UUID and device_profile_group_ID
|
||
for one accelerator request with the specified UUID.
|
||
|
||
Request
|
||
=======
|
||
.. rest_parameters:: parameters.yaml
|
||
|
||
- accelerator_request_uuid: accelerator_request_uuid
|

**Example response: get details of a specific accelerator request**
|
||
|
||
.. literalinclude:: ../../doc/api_samples/accelerator_requests/accelerator_requests-getone-resp.json
|
||
|
||
Create Accelerator Requests
|
||
---------------------------
|
||
|
||
.. rest_method:: POST /v2/accelerator_requests
|
||
|
||
Creates an accelerator request. The payload should have the following field:
|
||
|
||

|
||
|

|
||
Update Accelerator Requests
|
||
---------------------------
|
||
|
||
The Nova compute manager calls the Cyborg API PATCH /v2/accelerator_requests
|
||
to bind and unbind the ARQ with the host name, device’s RP UUID and instance UUID. This
|
||
is an asynchronous call which prepares or reconfigures the device in the
|
||
background.
|
||
|
||
.. rest_method:: PATCH /v2/accelerator_requests/{accelerator_request_uuid}
|
||
|
||
Updates:an accelerator request. The payload should have these fields:
|
||
|
||
Request
|
||
=======
|
||
.. rest_parameters:: parameters.yaml
|
||
|
||
- accelerator_request_uuid: accelerator_request_uuid
|
||
- hostname: hostname_bind_unbind_req
|
||
- device_rp_uuid: device_rp_uuid_bind_unbind_req
|
||
- instance_uuid: instance_uuid_bind_unbind_req
|
||
- instance_project_id: instance_project_id_bind_unbind_req
|
||
|
||
**Example patch curl**

**Example response: update an accelerator request**

||
.. rest_method:: DELETE /v2/accelerator_requests?arqs={accelerator_request_uuid}
|
||
|
||
Delete Accelerator Requests by instance uuid
