Implementations§

Source §

impl TPUDeviceInfo

Source

pub fn for_device_type(device_type: TPUDeviceType) -> Self

Return the published reference specifications for a given TPU type.

IMPORTANT: this is a static reference spec table (vendor datasheet figures such as peak FLOPS), NOT a hardware-detection result. It does not probe for, or assert the presence of, any physical TPU. The peak_flops values are theoretical peaks used only as reference denominators in metrics; nothing here measures an achieved rate.

Only TPUDeviceType::Simulated corresponds to something this build can actually run: a CPU-side numerical simulation of the device math (see TPUQuantumSimulator::new). The real-device rows exist purely as reference data for callers that have such hardware elsewhere.
