At the Google I/O conference held last week, Google officially announced the second generation of TPU, also known as Cloud TPU or TPU 2. However, Google has not introduced its new chip in detail, showing only a few photos. The next platform released an article today, based on Google's images and details, takes you to the TPU2 of Google. The quantum bits are compiled as follows: The first thing to say is that Google is unlikely to sell TPU chips, motherboards or servers to the public. For the mom

1. Oracle tracking File There are three types of Oracle trace files: one is the background alarm log file, which records the activity of background processes during database startup, shutdown, and running, such as creating tablespaces, creating rollback segments, some alter commands, log switching, and error messages. When the database fails, you should first check the file, but the information in the file is not necessarily related to any error status. The background alarm LOG file is saved in
