$taskset -p 1578
pid 1578's current affinity mask: 1
taskset is used to retrive or set the processor affinity
mask of either an existing process,given it's PID, or to
run a new process, given it's command name,with a
specified affinity mask. The Linux scheduler will then
honor the given affinity mask,ensuring that the process
in question runs only on allowed processors.
Display current readings of all sensor chips and set
limits as specified in the configuration file.
Assign a keycode event to the specified keyboard
scancode. Te kernel mathes these to it's own
keycodes.Scancodes in the range of 1-88 are hardwired in
the kernel,but the remaining scancodes can be assigned to
keycodes in the range of 1-127. Use getkeycodes to see
current assignment. Use showkey to discover what scancode
a key is sending.If you want to quit from the getkeycodes
command, just wait for a short time and it may offer the
Display or change the LED flag settings (Num Lock, Caps
Lock, and Scroll Lock) for the current virtual
terminal.WIth no options,display the current settings for
all the three flags. Can be used in a startup script to
set the initial state of the LEDs.
It is an important intermediate in chemical synthesis and
occurs naturally, most notably in the venom of bee and
lightweight objects in the linux kernel that enable users
to partition their multiprocessor machine.
Multiprocessing is the use of two or more central
processing units (CPUs) within a single computer system

-j [jobs], --jobs[=jobs]
Specifies the number of jobs (commands) to run
simultaneously. If there is more than one -j option, the
last one is effective. If the -j option is given without
an argument, make will not limit the number of jobs that
can run simultaneously.
machines with multiple processors can attach network
programs of higher priorities to a processor that is
little consumed or idle.
