qat.qlmaas.qpus.QLMaaSQPU

Remote QPUs are managed by QLMaaSQPU objects. These objects can be built using:

  • qlmaas.qpus module if a configuration exists on your computer

  • a QLMaaSConnection object (when the connection is defined manually). Please note that, even if there is no configuration file on your computer, instantiating a QLMaaSConnection object enables the qlmaas.qpus module

class qat.qlmaas.qpus.QLMaaSQPU(connection, name: str, constructor: SerializedArguments, description: str)

Class describing a QPU defined on a remote server.

If a configuration file is present on your computer, you can use the module qlmaas.qpus to instantiate a remote QPU:

from qlmaas.qpus import LinAlg

# Define a qpu
qpu = LinAlg()

Otherwise, if no configuration file is set on your machine, you can use a QLMaaSConnection object:

from qat.qlmaas import QLMaaSConnection

# Connect to the server
conn = QLMaaSConnection()

# Get remote QPU
LinAlg = conn.get_qpu("qat.qpus:LinAlg")
qpu = LinAlg()
submit(batch, meta_data: dict | None = None, mem_usage: int | None = None, core_usage: int | None = None, nb_nodes: int | None = None, max_time: int | timedelta | None = None)

Submit a batch to the server

Parameters:

  • batch (Batch) – batch to submit

  • meta_data (dict, optional) – override the meta_data of the batch

  • mem_usage (int, optional) – override default memory usage (in MB) calculation

  • core_usage (int, optional) – override default core usage calculation

  • nb_nodes (int, optional) – override default number of nodes

  • max_time (int | datetime.timedelta, optional) – maximum time for the job, indicated either with a timedelta, or in minutes (this argument may not be supported by the scheduler)

Returns:

asynchronous result

Return type:

AsyncResult
