+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/approved/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:
+
+Request
+=======
+.. rest_parameters:: parameters.yaml
+
+  - device_profile_name: device_profile_name
+
+**Example post curl**

+
+**Example response: create an accelerator request**
+
+.. literalinclude:: ../../../doc/api_samples/accelerator_requests/accelerator_requests-create-resp.json
+
+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
+
+**Example patch curl**
+
+.. literalinclude:: ../../../doc/api_samples/accelerator_requests/accelerator_requests-patch-curl.json
+
+**Example response: update an accelerator request**
+
+.. literalinclude:: ../../../doc/api_samples/accelerator_requests/accelerator_requests-update-resp.json
+
+Delete Accelerator Requests by ARQ uuid
+---------------------------------------
+
+.. rest_method:: DELETE /v2/accelerator_requests?arqs={accelerator_request_uuid}
+
+Delete Accelerator Requests by instance uuid
+--------------------------------------------
+
+.. rest_method:: DELETE /v2/accelerator_requests?instance={instance_uuid}
+
+Delete an accelerator request. No query parameters required.
+
+Response
+========
+
+Normal response codes: 204
+
+There is no body content for the response of a successful DELETE query
