CPU cores and TOP

(1/1)

PDP-8:
Sometimes I forget that I can use TOP to make sure that all my cores are up and running.  It is very simple:

When you bring up TOP, just hit the # 1 key.  Now all your cores will be seen.

Normally I use htop, or cat the proc filesystem, but I'm lazy and now this is part of muscle-memory when I bring up a system for the first time.

A few years ago I was diagnosing a problem and using no-apic/lapic/ioapic and so forth, and system felt sluggish.  Using top in this way quickly showed that I had shut down all the cores except for one.  Hasn't happened since.

It's just a habit now, but maybe some guys who don't use top much might use it just for this cpu core activity check.
