Please note, that by default these settings are in comments in the templates.

You have to uncomment them both in .env and in docker-compose.yml as well to take effect.

In the .env file these variables are present in a block:

- AIHUB_BACKEND_CPUSET=0
- JOBAGENT_CPUSET=2
- WEBAPI_AGENT_CPUSET_1=4
- WEBAPI_AGENT_CPUSET_2=6
- SCORING_AGENT_CPUSET=6
- PANOPTICON_VIZAPP_CPUSET=8
- PANOPTICON_PYTHON_CPUSET=8
- PANOPTICON_RSERVE_CPUSET=8

In the docker-compose.yml file you can find these variables one-by-one:

...
cpuset: ${AIHUB_BACKEND_CPUSET}
...
cpuset: ${JOBAGENT_CPUSET}
...
puset: ${WEBAPI_AGENT_CPUSET_1}
...
cpuset: ${WEBAPI_AGENT_CPUSET_2}
...
cpuset: ${SCORING_AGENT_CPUSET}
...
cpuset: ${PANOPTICON_VIZAPP_CPUSET}
...
cpuset: ${PANOPTICON_PYTHON_CPUSET}
...
cpuset: ${PANOPTICON_RSERVE_CPUSET}
...
