The IEI Mustang-V100-MX8 is an OEM version of the Intel® Vision Accelerator Design with Intel® Movidius™ VPUs. This guide assumes you have installed the Mustang-V100-MX8 and the Intel® Distribution of OpenVINO™ Toolkit.

Instructions in this guide for configuring your accelerator include:

1. Installing the required IEI* BSL reset software
2. Configuration settings for the hddldaemon service

Note

: This guide does not apply to Uzel* cards.

IEI Reset Software Installation

Using the IEI Mustang-V100-MX8 requires downloading and installing the most current software for your system.

Visit the IEI Download Center for the most current software and documentation. Search for Mustang-V100-MX8.

Download the appropriate software for your system, decompress the downloaded archive, enter the newly created directory, and run the install script:

On Linux*:

• Run the install.sh script with sudo, or as root.

On Windows*, do one of the following:

• GUI: Double-click install.bat
• CLI: Open a console with administrator privileges, cd into the directory, and run install.bat.

Mustang-V100-MX8 Service Configuration

The hddldaemon is a system service, a binary executable that is run to manage the computational workload on the board. It is a required abstraction layer that handles inference, graphics processing, and any type of computation that should be run on the video processing units (VPUs). Depending on the board configuration, there can be 8 or 16 VPUs.

Note

: Graphics and other specialized processing may require some custom development.

Conventions Used in This Document

<IE> refers to the following default OpenVINO™ Inference Engine directories:

• Linux:

/opt/intel/openvino_2022/inference_engine

• Windows:

C:\Program Files (x86)\IntelSWTools\openvino\inference_engine 

If you have installed OpenVINO™ in a different directory on your system, you will need to enter your unique directory path.

Service Configuration File Settings

Below are some possible configuration options.

Note

: After changing a configuration file, the hddldaemon must be restarted.

Recommended Settings

device_snapshot_mode
Changes the output of the hddldaemon to display a table with individual VPU statistics.

Default Setting:
"device_snapshot_mode": "none"

Suggested Setting:
"device_snapshot_mode": "full"

Supported Settings:

• none (default)
• base
• full

device_snapshot_style

Default Setting:
"device_snapshot_style": "table"

Recommended Setting:
"device_snapshot_style": "table"

The table setting presents labels on the left for each column and is recommended as easier to read.
The tape setting prints the labels in each column.

Supported Settings:

• tape
• table (default)

user_group
Restricts the service to group members.

Recommended setting depends on your unique system configuration.

Default Setting
"user_group": "users"

The hddldaemon may be restricted to a privileged group of users. The appropriate group will vary according to the local system configuration.

Supported Settings: Valid groups on the current system. The "users" group is a default group that exists on Windows and most Linux distributions.

Optional Recommended Settings:

"device_utilization" : "off"
This setting displays the percent of time each VPU is in use. It appears in the table column when turned on, or if "device_fps" is turned on.

"memory_usage" : "off"
This setting reports the amount of memory being used by each VPU.

"max_cycle_switchout": 3
Requires the squeeze scheduler. This setting might speed up performance significantly, depending on the app.

Note

: This setting works in conjunction with: max_task_number_switch_out.

"client_fps" : "off"
This setting reports the total FPS for the dispatching hddl_service (which will have one or more clients per app).

debug_service
"debug_service": "false"
(default: "true")
