This refreshes the display every second. To make the refresh rate faster, decrease 1 to a lower number(e.g. 0.5). The number on the most left side is the id of the LPU™.
Reset the LPU device
Instead of pressing Ctrl+C, please reset the device. First, check the device id with the hyperdex-smi. Next reset the device with the following code.
Create Network Table
This creates network table which is necessary to use multiple LPUs.
