I wrote the below code

    def wrapper(maker):
        @local_optimizer([op], inplace=True)
        @wraps(maker)
        def opt(node):
            if ((type(node.op) != op) or node.op.inplace):
                return
            inputs = list(node.inputs)
            alloc = inputs[idx]
            if (alloc.owner and isinstance(alloc.owner.op, GpuAllocEmpty) and (len(alloc.clients) > 1)):
                alloc_op = GpuAllocEmpty(alloc.owner.op.dtype, alloc.owner.op.context_name)
                inputs[idx] = alloc_op(*alloc.owner.inputs)
            return maker(node, inputs)
        return opt
    return wrapper
