mlos_bench.environments.local.local_env module

Scheduler-side benchmark environment to run scripts locally.

class mlos_bench.environments.local.local_env.LocalEnv(*, name: str, config: dict, global_config: dict | None = None, tunables: TunableGroups | None = None, service: Service | None = None)

Bases: ScriptEnv

Scheduler-side Environment that runs scripts locally.

Attributes:

parameters

Key/value pairs of all environment parameters (i.e., const_args and tunable_params).

tunable_params

Get the configuration space of the given environment.

Methods

new(*, env_name, class_name, config[, ...])	Factory method for a new environment with a given config.
pprint([indent, level])	Pretty-print the environment configuration.
run()	Run a script in the local scheduler environment.
setup(tunables[, global_config])	Check if the environment is ready and set up the application and benchmarks, if necessary.
status()	Check the status of the benchmark environment.
teardown()	Clean up the local environment.

run() → Tuple[Status, datetime, Dict[str, int | float | str | None] | None]

Run a script in the local scheduler environment.

Returns:

(status, timestamp, output)(Status, datetime, dict)

3-tuple of (Status, timestamp, output) values, where output is a dict with the results or None if the status is not COMPLETED. If run script is a benchmark, then the score is usually expected to be in the score field.

setup(tunables: TunableGroups, global_config: dict | None = None) → bool

Check if the environment is ready and set up the application and benchmarks, if necessary.

Parameters:

tunablesTunableGroups

A collection of tunable OS and application parameters along with their values. In a local environment these could be used to prepare a config file on the scheduler prior to transferring it to the remote environment, for instance.

global_configdict

Free-format dictionary of global parameters of the environment that are not used in the optimization process.

Returns:

is_successbool

True if operation is successful, false otherwise.

status() → Tuple[Status, datetime, List[Tuple[datetime, str, Any]]]

Check the status of the benchmark environment.

Returns:

(benchmark_status, timestamp, telemetry)(Status, datetime, list)

3-tuple of (benchmark status, timestamp, telemetry) values. timestamp is UTC time stamp of the status; it’s current time by default. telemetry is a list (maybe empty) of (timestamp, metric, value) triplets.

teardown() → None

Clean up the local environment.
