mindspore.hal.memory_reserved

mindspore.hal.memory_reserved(device_target=None)[source]

Returns the total amount of memory currently managed by the memory pool.

Note

The api will be deprecated, please use the api mindspore.runtime.memory_reserved() instead.

Note

If device_target is not specified, get the device capability of the current backend set by context.
For the CPU backend, 0 is always returned.

Parameters: device_target (str, optional) – The device name of backend, should be one of "CPU", "GPU" and "Ascend". Default value: None.
Returns: int, in Byte.

Examples

>>> import mindspore as ms
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> a = Tensor(np.ones([1, 2]), ms.float32)
>>> b = Tensor(np.ones([1, 2]), ms.float32)
>>> c = ops.add(a, b).asnumpy()
>>> print(ms.hal.memory_reserved())
