Procedure for installing and launching GPU accelerators on Rikor server motherboards based on Intel Xeon Scalable CPU

Preface

This manual has been tested for the following types and families of GPU accelerators:

• Nvidia Tesla T4 – simultaneous operation of 3 accelerators on the motherboard;
• Nvidia Quadro P620 – simultaneous operation of 4 accelerators on the motherboard.

Procedure for launching graphics accelerators

Nvidia Tesla T4

1. Remove power from the server;

2. Install graphics accelerators in the PCIe x16 slots of the motherboard (x8 with the ability to install x16 expansion cards in them);

3. Apply power to the server;

4. Wait for the image to appear on the screen. Hold down the "ESC" key and wait to enter the BIOS menu;

5. Go to Setup Utility -> Advance -> Socket Configuration -> Common RefCode Configuration;

6. Make settings as shown below; the values ​​of the first three functions are required and the rest are default:

	Common RefCode Configuration
1	MMCFG	512M
2	MMIO High Base	56T
3	MMIO High Granularity Size	1024G
4	Isoc Mode	Auto
5	Numa	Enabled
6	Publish SRAT	Enabled
7	SRAT Memory Hot Plug	Disabled
8	SRAT CPU Hot Plug	Disabled

7. Press "F10" button (Save and exit).

Nvidia Quadro P620

1. Without installing graphics accelerators apply power to the server;

2. Wait for the image to appear on the screen. Hold down the "ESC" key and wait to enter the BIOS menu;

3. Go to Setup Utility -> Advance -> Video Configuration;

4. Set Display Mode option to the "On Board First" state;

5. Press "F10" button (Save and exit);

6. Wait until the server restarts (the changes will take effect). Remove power from the server;

7. Install graphics accelerators in the PCIe x16 slots of the motherboard (x8 with the ability to install x16 expansion cards in them);

8. Apply power to the server;

9. Wait for the image to appear on the screen. Hold down the "ESC" key and wait to enter the BIOS menu;
