Returns:
enqueue_copy_to
enqueue_copy_to(self, dst_ptr: UnsafePointer[Scalar[dtype], MutAnyOrigin])
Enqueues an asynchronous copy from this buffer to host memory.
This method schedules a memory copy operation from this device buffer to the specified host memory location. The operation is asynchronous and will be executed in the stream associated with this buffer's context.
Args:
- dst_ptr (
UnsafePointer[Scalar[dtype], MutAnyOrigin]): Pointer to the destination host memory location.
enqueue_copy_to(self, dst: HostBuffer[dtype])
Enqueues an asynchronous copy from this buffer to host memory.
This method schedules a memory copy operation from this device buffer to the specified host memory location. The operation is asynchronous and will be executed in the stream associated with this buffer's context.
Args:
- dst (
HostBuffer[dtype]): Host buffer to copy to.
Raises:
If the copy operation fails.
enqueue_copy_from
enqueue_copy_from(self, src_ptr: UnsafePointer[Scalar[dtype], MutAnyOrigin])
Enqueues an asynchronous copy from host memory to this buffer.
This method schedules a memory copy operation from the specified host memory location to this device buffer. The operation is asynchronous and will be executed in the stream associated with this buffer's context.
Args:
- src_ptr (
UnsafePointer[Scalar[dtype], MutAnyOrigin]): Pointer to the source host memory location.
Raises:
If the copy operation fails.
enqueue_copy_from(self, src: HostBuffer[dtype])
Enqueues an asynchronous copy from host memory to this buffer.
This method schedules a memory copy operation from the specified host memory location to this device buffer. The operation is asynchronous and will be executed in the stream associated with this buffer's context.
Args:
- src (
HostBuffer[dtype]): Host buffer to copy from.
Raises:
If the copy operation fails.
