}

Kernel-specific metadata stored in checkpoint.

Fields

kernel_id: String

Unique kernel identifier.

kernel_type: String

Kernel type (e.g., “fdtd_3d”, “wave_sim”).

current_step: u64

Current simulation step.

grid_size: (u32, u32, u32)

Grid dimensions.

tile_size: (u32, u32, u32)

Tile/block dimensions.

hlc_timestamp: HlcTimestamp

HLC timestamp at checkpoint time.

custom: HashMap<String, String>

Custom key-value metadata.
