Struct EpistemicGpuFinalResultTransferTrace 

pub struct EpistemicGpuFinalResultTransferTrace {
    pub final_output_rows: usize,
    pub final_output_column_count: usize,
    pub final_output_row_width_bytes: usize,
    pub final_output_payload_bytes: u64,
    pub row_count_device_reads: u32,
    pub tracked_data_plane_dtoh_calls: u64,
    pub tracked_data_plane_dtoh_bytes: u64,
}

Trace accounting for the bounded final-result transfer after the GPU hot path.

Fields

final_output_rows: usize

Logical rows in the final device-resident output buffer.

final_output_column_count: usize

Number of final output columns that a caller may export.

final_output_row_width_bytes: usize

Bytes in one final output row.

final_output_payload_bytes: u64

Bounded data-plane payload bytes represented by the final output.

row_count_device_reads: u32

Device row-count metadata reads used for this accounting.

tracked_data_plane_dtoh_calls: u64

Data-plane device-to-host calls issued by accepted execution. Execution returns a device buffer, so this is zero.

tracked_data_plane_dtoh_bytes: u64

Data-plane device-to-host bytes issued by accepted execution. Execution returns a device buffer, so this is zero.

Implementations

impl EpistemicGpuFinalResultTransferTrace

pub fn from_final_output( provider: &CudaKernelProvider, final_output: &CudaBuffer, ) -> Result<Self>

Account for the final device-resident output after the hot-path budget window closes.

pub fn require_matches_final_output( &self, construct: &str, final_output: &CudaBuffer, ) -> Result<()>

Require retained final-result transfer accounting to match the final device buffer.

Trait Implementations

impl Clone for EpistemicGpuFinalResultTransferTrace

fn clone(&self) -> EpistemicGpuFinalResultTransferTrace

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EpistemicGpuFinalResultTransferTrace

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EpistemicGpuFinalResultTransferTrace

fn eq(&self, other: &EpistemicGpuFinalResultTransferTrace) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
