Struct KernelAttributes 

pub struct KernelAttributes {
    pub max_threads_per_block: u32,
    pub num_regs: u32,
    pub static_shared_bytes: u32,
    pub local_bytes: u32,
}

Per-kernel resource usage, as reported by the JIT for a compiled kernel.

These are properties of the cubin the driver actually produced — not of the PTX we emitted — which is why they can only be read back after a module load.

Fields

max_threads_per_block: u32

Largest block size this kernel can be launched with (CU_FUNC_ATTRIBUTE_MAX_THREADS_PER_BLOCK).

num_regs: u32

Registers used per thread (CU_FUNC_ATTRIBUTE_NUM_REGS).

static_shared_bytes: u32

Statically declared shared memory, bytes (CU_FUNC_ATTRIBUTE_SHARED_SIZE_BYTES).

local_bytes: u32

Per-thread local memory, bytes (CU_FUNC_ATTRIBUTE_LOCAL_SIZE_BYTES). Non-zero means the kernel spilled registers to local memory — legal, but a performance cliff.
