Structural statistics about a compiled kernel’s emitted PTX.

These describe the instruction mix and declared resource usage in KAIO’s generated PTX — useful for inspection and comparison between kernel variants, but not a substitute for runtime profiling. Final hardware register allocation and occupancy may differ from these counts after the CUDA driver’s backend compilation (PTX → SASS).

Fields

total_instructions: usize

Total instructions (excludes labels and comments).

ld_global: usize

ld.global count.

st_global: usize

st.global count.

ld_shared: usize

ld.shared count.

st_shared: usize

st.shared count.

bar_sync: usize

bar.sync count.

mma: usize

mma.sync instruction count (all tensor-core shapes).

cp_async: usize

cp.async.ca.shared.global instruction count.

cp_async_commit: usize

cp.async.commit_group instruction count.

cp_async_wait: usize

cp.async.wait_group instruction count.

fma: usize

fma instruction count.

arith_other: usize

Non-FMA arithmetic instructions (add, mul, sub, etc.).

mov: usize

mov instruction count.

cvt: usize

cvt instruction count.

branches: usize

Branch instructions (bra, @pred bra).

setp: usize

setp comparison-to-predicate instructions.

registers_r: u32

%r registers (32-bit integer).

registers_rd: u32

%rd registers (64-bit integer).

registers_f: u32

%f registers (f32).

registers_fd: u32

%fd registers (f64).

registers_p: u32

%p registers (predicate).

Trait Implementations

impl Debug for KernelStats

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

Formats the value using the given formatter.

impl Default for KernelStats

fn default() -> KernelStats

Returns the “default value” for a type.

impl PartialEq for KernelStats

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