Configurations for IEI Mustang-V100-MX8-R10 Card

Note

These steps are only required for IEI Mustang-V100-MX8-R10 card. IEI Mustang-V100-MX8-R11 card doesn’t require any additional steps and it’s completely configured using the general guidance

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 OpenVINO™ Runtime.

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.

Installing IEI Reset Software

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, extract the downloaded archive file, 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.

Configuring Mustang-V100-MX8 Service

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

<OV> refers to the following default OpenVINO™ Runtime directories:

• Linux:

/opt/intel/openvino_2022/runtime

• Windows:

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

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

Setting	Default value	Recommended value	Supported values	Description
device_snapshot_mode	"none"	"full"	"none" (default) "base" "full"	Changes the output of the hddldaemon to display a table with individual VPU statistics.
device_snapshot_style	"table"	"table" The table setting presents labels on the left for each column and is recommended as easier to read.	"table" (default) "tape" The "tape" setting prints the labels in each column.	Sets the style for device snapshot.
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.	Recommended setting depends on your unique system configuration.	Valid groups on the current system. The "users" group is a default group that exists on Windows and most Linux distributions.	Restricts the service to group members.

Optional Recommended Settings

Setting	Recommended Value	Description
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 that 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	"false"	This setting defines whether to display service log information. The default value is "true"
