Struct GpuExecutionTelemetry 

pub struct GpuExecutionTelemetry {
    pub h2d_bytes: usize,
    pub d2h_bytes: usize,
    pub factorization_count: usize,
    pub handle_creation_count: usize,
    pub kernel_launch_count: usize,
    pub cpu_fallback_count: usize,
    pub cpu_fallback_reasons: Vec<String>,
    pub context_id: usize,
}

Monotonic counters describing what the GPU-resident solver actually did on the current thread. Snapshot with telemetry_snapshot; reset with telemetry_reset.

Fields

h2d_bytes: usize

Bytes uploaded host→device.

d2h_bytes: usize

Bytes read back device→host.

factorization_count: usize

Cholesky / Schur factorizations performed on the device.

handle_creation_count: usize

cuBLAS / cuSOLVER / stream handle creations.

kernel_launch_count: usize

Device kernel launches (per-row + border solves).

cpu_fallback_count: usize

Times a path that intended to use the device fell back to the CPU.

cpu_fallback_reasons: Vec<String>

Human-readable reasons recorded alongside each CPU fallback.

context_id: usize

Opaque context identifier of the device this thread last touched (e.g. the CUDA device ordinal), 0 when no device was used.

Trait Implementations

impl Clone for GpuExecutionTelemetry

fn clone(&self) -> GpuExecutionTelemetry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuExecutionTelemetry

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

Formats the value using the given formatter.

impl Default for GpuExecutionTelemetry

fn default() -> GpuExecutionTelemetry

Returns the “default value” for a type.

impl Eq for GpuExecutionTelemetry

impl PartialEq for GpuExecutionTelemetry

fn eq(&self, other: &GpuExecutionTelemetry) -> 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.
