Mojo function

fence_proxy_tensormap_generic_sys_acquire

def fence_proxy_tensormap_generic_sys_acquire[dtype: AnyType](ptr: Pointer[dtype], size: Int32)

Acquires a system-wide memory fence for tensor map operations.

This function establishes a memory fence that ensures proper synchronization between tensor map operations and system memory. It guarantees that all previous memory operations are completed before subsequent tensor map accesses.

Note:

This is a low-level synchronization primitive typically used in conjunction with TMA (Tensor Memory Access) operations on NVIDIA GPUs.

Parameters:

• ​dtype (AnyType): The data type of the tensor map object being synchronized.

Args:

• ​ptr (Pointer[dtype]): Pointer to the tensor map object in system memory that needs to be synchronized.
• ​size (Int32): The size in bytes of the tensor map object being synchronized.
