Module

`gpu::metal::emulated`

cheatah-gpu v0.5.1-alpha — Biome Standard 0.6.3-alpha

Classes

DispatchShape — The full shape of one dispatch, as a 3-D-aware stand-in kernel receives it.
Extent — A three-axis extent, mirroring MTL::Size — width × height × depth, unused axes 1.

Functions

fn register_kernel · 2 overloads

void register_kernel(const char *name, void(*fn)(void **buffers, unsigned buffer_count, unsigned long grid_width))#

void register_kernel(const char *name, void(*fn)(void **buffers, unsigned buffer_count, const DispatchShape &shape))#

Parameters

`name`	the kernel/function name a pipeline is built for (matches newFunctionWithName).
`fn`	called per dispatch as fn(buffers, buffer_count, grid_width): `buffers[i]` is the bound buffer at index `i` (or null), `grid_width` is the dispatched thread count along x.

Complexity

O(1) registration.

Host allocation

none (stores the function pointer).

fn unsigned long live_objects() #

The number of emulator objects still alive — 0 means nothing leaked.

Meaningful when built with -DCHEATAH_GPU_METAL_LEAKCHECK=1 (otherwise always 0); compiled out for production so there is no tracking overhead. This ALERTS on leaks; it does not enforce RAII.

Returns

count of live emulated Metal objects.

Complexity

O(1).

Host allocation

none.
