DataParallelIntensityScenario

Communication scenarios · Implementation: mlsysim/engine/scenario_definitions/communication.py.

Construct this scenario with keyword inputs. The fields below show the types and defaults declared by this class.

Communication intensity of one data-parallel worker of workload.

Notes

Equation: Compose mlsysim.solvers.CommunicationIntensityModel.

Assumptions: The stated fields are inputs to mlsysim.solvers.CommunicationIntensityModel; its documented validity regime, units, and modeling choices apply unchanged.

Excludes: This scenario adds no measurement, empirical calibration, or mechanisms beyond mlsysim.solvers.CommunicationIntensityModel.

References

Derivation: this scenario binds its input fields to the referenced implementation contracts: mlsysim.solvers.CommunicationIntensityModel. The methods below identify any additional arithmetic.

Examples

>>> from mlsysim import Scenarios
>>> case = Scenarios.Gpt3DataParallelIntensity
>>> type(case.result).__name__
'CommunicationIntensityResult'

result

engine.scenario_types.DataParallelIntensityScenario.result

Evaluate this scenario through mlsysim.solvers.CommunicationIntensityModel.solve. Equation: pass the stated fields to that implementation; its contract defines the calculation and feasibility tests. Units: each returned field follows the referenced result schema; no independent equation is evaluated by this wrapper.
