Mojo function

parallel_memcpy

def parallel_memcpy[dtype: DType](*, dest: Optional[Pointer[Scalar[dtype], origin]], src: Optional[Pointer[Scalar[dtype], origin]], count: Int, count_per_task: Int, num_tasks: Int)

Copies count elements from a memory buffer src to dest in parallel by spawning num_tasks tasks each copying count_per_task elements.

Safety: dest or src can only be None when count == 0.

Deprecated: 'parallel_memcpy' is deprecated, use 'unsafe_parallel_memcpy' instead

Parameters:

• ​dtype (DType): The element dtype.

Args:

• ​dest (Optional[Pointer[Scalar[dtype], origin]]): The destination buffer.
• ​src (Optional[Pointer[Scalar[dtype], origin]]): The source buffer.
• ​count (Int): Number of elements in the buffer.
• ​count_per_task (Int): Task size.
• ​num_tasks (Int): Number of tasks to run in parallel.

def parallel_memcpy[dtype: DType](*, dest: Optional[Pointer[Scalar[dtype], origin]], src: Optional[Pointer[Scalar[dtype], origin]], count: Int)

Copies count elements from a memory buffer src to dest in parallel.

Safety: dest or src can only be None when count == 0.

Deprecated: 'parallel_memcpy' is deprecated, use 'unsafe_parallel_memcpy' instead

Parameters:

• ​dtype (DType): The element dtype.

Args:

• ​dest (Optional[Pointer[Scalar[dtype], origin]]): The destination pointer.
• ​src (Optional[Pointer[Scalar[dtype], origin]]): The source pointer.
• ​count (Int): The number of elements to copy.
