How to disable GPU Usage

This article explains how to disable GPU and/or limit which GPUs SAFR users. This is assumed to be useful only for testing and not something that is likely needed by most users.

Argus or Virgo

Use Windows Device Manager and disable the Nvidia Device

Virgo

Set following on each feed:

accelerator=cpu, gpu or auto
accelerator.gpu-id attribute

virgo_accelerator_settings

Windows

Disable the device in Windows Device Manager

File: C:\Program Files\RealNetworks\SAFR\face-service\config\config

HTFS will automatically use all available GPUs. You need to update the config file to tell it what GPUs you want it to use as follows:

#use_gpus=0,1 #list gpu ids to use or use all

use_gpus=all

Switch All compute from GPU to CPU:

#use_pipeline=gpu,cpu,both #definition of pipline to use auto uses gpu if a

use_pipline=auto

Linux

Service (HTFS / Face Service)

HTFS will automatically use all available GPUs. You need to update the config file to tell it what GPUs you want it to use as follows:

File: /opt/RealNetworks/SAFR/face-service/config/config

#use_gpus=0,1 #list gpu ids to use or use all

use_gpus=all

Switch All compute from GPU to CPU:

#use_pipeline=gpu,cpu,both #definition of pipline to use auto uses gpu if a

use_pipline=auto

Video Gateway

In case of virgo running in Docker you can update the compose file and bounce the virgo instance.

Run following commands:

cd /opt/RealNetworks/SAFR/virgo/app/

docker-compose down

Edit docker-compose.yml to add in the environment variable as follows:

docker-compose.yml file location:

/opt/RealNetworks/SAFR/virgo/app

version: "3.6"

services:

virgo:

image: safr_virgo:VIRGO_VERSION

container_name: safr_virgo

restart: on-failure

pid: "host"

environment:

- NVIDIA_VISIBLE_DEVICES=0

volumes:

- /opt/RealNetworks/SAFR/virgo/config/:/etc/virgo

- VIRGO_PATH:/mnt/virgo-workspace

# docker-compose up -d

Restore docker with following command:

docker-compose up
