Restrictions

The HCCL Performance Tester starts devices based on the configured number of NPUs used in training on a single compute node. If the number is x (that is, -p is set to x), the tester starts x devices consecutively from device 0.

For the Atlas Training Series Product, -p can be set to 1, 2, 4, or 8, and the started device ID is [0, p – 1].
