This folder contains seven zsh scripts:

    cont
    init-be
    kill-be-sw
    paths
    stop
    task
    what

Those are used to control the best-effort core
software. This is done by means of a cgroup.

The path to the cgroup is defined in the script
"paths". The cgroup represents the BE software with
two files, whose locations are also defined in
"paths".

But you don't need to run "paths" explicitly. Instead,
initialize the cgroup with "init-be".

One of the files of the cgroup holds the state of the
BE core. If the state is FROZEN, BE software will not
run; if the state is THAWED, BE software will run just
like any other Linux processes (but only on the BE
core). Set the state to FROZEN with "stop"; set it to
THAWED with "cont".

The other file of the cgroup holds the PIDs that run
on the BE core. (Note: Not all of them are processes
that are launced explicitly by the user, some may be
forked by other processes.) To add a PID to this file,
and to run it on the BE core, use "task", e.g.,

    $ task forever

Here, try "cont" and "stop" to [un]freeze the infinite
loop.

To query the state of the BE core, and have the PIDs
running there listed, use "what".

To kill all processes on the BE core, use
"kill-be-sw".
