    GlobalThreadId,
    SyncThreads,
    Now,
    AtomicAdd,

RingContext method mappings to CUDA intrinsics.

Variants

ThreadId

ctx.thread_id() -> threadIdx.x

BlockId

ctx.block_id() -> blockIdx.x

GlobalThreadId

ctx.global_thread_id() -> blockIdx.x * blockDim.x + threadIdx.x

SyncThreads

ctx.sync_threads() -> __syncthreads()

Now

ctx.now() -> HLC timestamp

AtomicAdd

ctx.atomic_add(ptr, val) -> atomicAdd(ptr, val)

WarpShuffle

ctx.warp_shuffle(val, lane) -> __shfl_sync(0xFFFFFFFF, val, lane)

LaneId

ctx.lane_id() -> threadIdx.x % 32

WarpId

ctx.warp_id() -> threadIdx.x / 32

Implementations

impl ContextMethod

pub fn from_name(name: &str) -> Option<Self>

Parse a method name to context method.

pub fn to_cuda(&self, args: &[String]) -> String

Generate CUDA code for this context method.

pub fn is_statement(&self) -> bool

Check if this method is a statement (vs expression).

Trait Implementations

impl Clone for ContextMethod

fn clone(&self) -> ContextMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextMethod

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

Formats the value using the given formatter.

impl PartialEq for ContextMethod

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