TPU XIO Board Introduction
Startup
When the board is installed and connected, follow the instructions in this section to start
operation.
1. Power on the system. Follow the appropriate power-on instructions for the system's
configuration.
2. Log on.
3. Verify that the three LEDs on the board illuminate green.
If any LED fails to illuminate, ensure that the correct software is installed and
configured; refer to “Software Installation and Configuration” on page 4. If any LED
still does not illuminate, contact your SGI authorized service provider.
4. Verify that the board was located by the operating system during the bootup:
%hinv | grep Tensor
External Tensor Processing Unit, module 1 slot 11
External Tensor Processing Unit, module 1 slot 8
External Tensor Processing Unit, module 1 slot 10
External Tensor Processing Unit, module 1 slot 7
External Tensor Processing Unit, module 1 slot 9
External Tensor Processing Unit, module 1 slot 4
External Tensor Processing Unit, module 1 slot 6
External Tensor Processing Unit, module 1 slot 5
External Tensor Processing Unit, module 1 slot 3
The number after module and slot should correctly identify the chassis and XIO
slot into which you installed the board. There will be other lines in this display;
however, verify the line that corresponds to the board you installed.
Note: Device directories that correspond to the TPUs installed in the system reside
in /hw/tpu. Additionally, the TPU requires the device directory /hw/tpu/any.
