Don't detect all cpus with last docker images of sagemath

[lerouxje]

hello,

• with version 8.0 of sagemath/sagemath image docker, i detect all my cpus: $ docker run -it --rm sagemath/sagemath:8.0 sage SageMath version 8.0, Release Date: 2017-07-21 Forcing sage-location, probably because a new package was installed. Updating various hardcoded paths... (Please wait at most a few minutes.) DO NOT INTERRUPT THIS. Done updating paths. sage: sage.parallel.ncpus.ncpus() 8

• with version 8.1 and latest i detect only one cpu: docker run -it --rm sagemath/sagemath:latest sage ┌───────────────────────────────────────────────────────────────┐ │ SageMath version 8.2, Release Date: 2018-05-05 │ │ Type "notebook()" for the browser-based notebook interface. │ │ Type "help()" for help. │ └───────────────────────────────────────────────────────────────┘ Setting permissions of DOT_SAGE directory so only you can read and write it. sage: sage.parallel.ncpus.ncpus() 1

and if i launch "nproc" in container i have all my cpus: docker run -it --rm sagemath/sagemath:latest nproc 8

Can you help me , please

This is not an issue specific to the docker image, the same issue happens for me when I build 8.1+ from scratch.

Please report this issue at https://trac.sagemath.org instead. Sage's developers are not actively monitoring the issues on github.

Feel free to add "saraedum" to the Cc list on the trac ticket. I am happy to have a look at this then.
