I have access to the Linux account (named jupyter), but when running certain commands, it cannot utilize all of the available CPUs. Once I switch to another user I can use all CPUs.
I use this command for tests:
for i in $(seq $(getconf _NPROCESSORS_ONLN)); do yes > /dev/null & done
I'm checking CPU load with
When I run this command on user jupyter, I get a total of 98.6% CPU usage (i.e., an average of 12.3% on each of eight CPUs).

When I run this command on user test1, I get 100.0% CPU usage on each CPU.

User jupyter is default user for this notebook.
