Module contents

This module provides an auto-tuning infrastructure for TileLang (tl) programs. It includes functionality to JIT-compile TileLang programs into a runnable kernel adapter using TVM.

tilelang.jit.compile(func: Optional[PrimFunc] = None, out_idx: Optional[Union[List[int], int]] = None, execution_backend: Literal['dlpack', 'ctypes', 'cython'] = 'cython', target: Union[str, Target] = 'auto', target_host: Optional[Union[str, Target]] = None, verbose: bool = False, pass_configs: Optional[Dict[str, Any]] = None) → JITKernel

Compile the given TileLang PrimFunc with TVM and build a JITKernel.

tilelang.jit.jit(func: Optional[Callable] = None, *, out_idx: Optional[Union[List[int], int]] = None, execution_backend: Literal['dlpack', 'ctypes', 'cython'] = 'cython', target: Union[str, Target] = 'auto', verbose: bool = False, **pass_config_kwargs: Optional[Dict[str, Any]]) → BaseKernelAdapter

A decorator (or decorator factory) that JIT-compiles a given TileLang PrimFunc into a runnable kernel adapter using TVM. If called with arguments, it returns a decorator that can be applied to a function. If called without arguments, it directly compiles the given function.

Parameters:

• func (Callable, optional) – The TileLang PrimFunc to JIT-compile. If None, this function returns a decorator that expects a TileLang PrimFunc.

• out_idx (Union[List[int], int], optional) – The index (or list of indices) of the function outputs. This can be used to specify which outputs from the compiled function will be returned.

• execution_backend (Literal["dlpack", "ctypes"], optional) – The wrapper type to use for the kernel adapter. Currently, only “dlpack” and “ctypes” are supported.

• target (Union[str, Target], optional) – The compilation target for TVM. If set to “auto”, an appropriate target will be inferred automatically. Otherwise, must be one of the supported strings in AVALIABLE_TARGETS or a TVM Target instance.

Returns:

An adapter object that encapsulates the compiled function and can be used to execute it.

Return type:

BaseKernelAdapter

Raises:

AssertionError – If the provided target is an invalid string not present in AVALIABLE_TARGETS.
