Struct KernelContext

pub struct KernelContext {
    pub thread_idx: Dim3,
    pub block_idx: Dim3,
    pub block_dim: Dim3,
    pub grid_dim: Dim3,
    pub barrier: Option<Arc<Barrier>>,
}

Expand description

Kernel execution context that mirrors CUDA’s built-in variables.

Each thread in a kernel launch receives its own KernelContext via thread-local storage, providing access to threadIdx, blockIdx, blockDim, and gridDim equivalents.

Fields§

§thread_idx: Dim3

Thread index within the block (analogous to CUDA threadIdx)

§block_idx: Dim3

Block index within the grid (analogous to CUDA blockIdx)

§block_dim: Dim3

Dimensions of each block (analogous to CUDA blockDim)

§grid_dim: Dim3

Dimensions of the grid (analogous to CUDA gridDim)

§barrier: Option<Arc<Barrier>>

Optional barrier for sync_threads() synchronisation within a block
