Abstract: An information acquisition method and apparatus, an electronic device, and a storage medium are suggested, which relates to the field of artificial intelligence (AI) such as machine learning and distributed storage. The method may include: determining hardware devices located on a to-be-processed node in response to determining that a trigger condition is met; selecting an x processing unit (XPU) from the hardware devices; and acquiring predetermined information of the XPU by using a system management interface (SMI) management tool corresponding to the XPU, the predetermined information including model information of the XPU.

Abstract: Some embodiments of this application provides a reversing valve and a heat exchange system having the same. The reversing valve includes: a valve seat having a first flow channel, a second flow channel, a third flow channel, and a fourth flow channel; a first valve body controlling communication between the first flow channel and the third flow channel; a second valve body controlling communication between the first flow channel and the fourth flow channel; a third valve body controlling communication between the third flow channel and the second flow channel. When the reversing valve is in a first operation state, the second valve body controls the first flow channel to communicate with the fourth flow channel. When the reversing valve is in a second operation state, the first valve body controls the first flow channel to communicate with the third flow channel.
