Accelerator API

Accelerator API

The Accelerator Class

The accelerator high-level interface is available through the accelerator member of a Connection object. The accelerator member will only be added if the service is detected.

Device Operations

class openstack.accelerator.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
devices(**query)

Retrieve a generator of devices.

Parameters:query (kwargs) – Optional query parameters to be sent to restrict the devices to be returned. Available parameters include: * hostname: The hostname of the device. * type: The type of the device. * vendor: The vendor ID of the device. * sort: A list of sorting keys separated by commas. Each sorting key can optionally be attached with a sorting direction modifier which can be asc or desc. * limit: Requests a specified size of returned items from the query. Returns a number of items up to the specified limit value. * marker: Specifies the ID of the last-seen item. Use the limit parameter to make an initial limited request and use the ID of the last-seen item from the response as the marker parameter value in a subsequent limited request.
Returns:A generator of device instances.
get_device(uuid, fields=None)

Get a single device.

Parameters:uuid – The value can be the UUID of a device.
Returns:One Device
Raises:ResourceNotFound when no device matching the criteria could be found.

Deployable Operations

class openstack.accelerator.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
deployables(**query)

Retrieve a generator of deployables.

Parameters:query (kwargs) – Optional query parameters to be sent to restrict the deployables to be returned.
Returns:A generator of deployable instances.
get_deployable(uuid, fields=None)

Get a single deployable.

Parameters:uuid – The value can be the UUID of a deployable.
Returns:One Deployable
Raises:ResourceNotFound when no deployable matching the criteria could be found.
update_deployable(uuid, patch)

Reconfig the FPGA with new bitstream.

Parameters:
  • uuid – The value can be the UUID of a deployable
  • patch – The information to reconfig.
Returns:

The results of FPGA reconfig.

Device Profile Operations

class openstack.accelerator.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
device_profiles(**query)

Retrieve a generator of device profiles.

Parameters:query (kwargs) – Optional query parameters to be sent to restrict the device profiles to be returned.
Returns:A generator of device profile instances.
create_device_profile(**attrs)

Create a device_profile.

Parameters:attrs (kwargs) – a list of device_profiles.
Returns:The list of created device profiles
delete_device_profile(name_or_id, ignore_missing=True)

Delete a device profile

Parameters:
  • name_or_id – The value can be either the ID or name of a device profile.
  • ignore_missing (bool) – When set to False ResourceNotFound will be raised when the device profile does not exist. When set to True, no exception will be set when attempting to delete a nonexistent device profile.
Returns:

None

get_device_profile(uuid, fields=None)

Get a single device profile.

Parameters:uuid – The value can be the UUID of a device profile.
Returns:One :class: ~openstack.accelerator.v2.device_profile.DeviceProfile
Raises:ResourceNotFound when no device profile matching the criteria could be found.

Accelerator Request Operations

class openstack.accelerator.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
accelerator_requests(**query)

Retrieve a generator of accelerator requests.

Parameters:query (kwargs) – Optional query parameters to be sent to restrict the accelerator requests to be returned.
Returns:A generator of accelerator request instances.
create_accelerator_request(**attrs)

Create an ARQs for a single device profile.

Parameters:attrs (kwargs) – request body.
Returns:The created accelerator request instance.
delete_accelerator_request(name_or_id, ignore_missing=True)

Delete a device profile :param name_or_id: The value can be either the ID or name of an accelerator request. :param bool ignore_missing: When set to False ResourceNotFound will be raised when the device profile does not exist. When set to True, no exception will be set when attempting to delete a nonexistent accelerator request. :returns: None

get_accelerator_request(uuid, fields=None)

Get a single accelerator request. :param uuid: The value can be the UUID of a accelerator request. :returns: One :class: ~openstack.accelerator.v2.accelerator_request.AcceleratorRequest :raises: ResourceNotFound when no accelerator request matching the criteria could be found.

update_accelerator_request(uuid, properties)

Bind/Unbind an accelerator to VM. :param uuid: The uuid of the accelerator_request to be bound/unbound. :param properties: The info of VM that will bind/unbind the accelerator. :returns: True if bind/unbind succeeded, False otherwise.
