NAME
	coreup - Enable all CPU cores
	coredown - Disable all but one CPU core

SYNOPSIS
	coreup [count]
	coredown [count]

DESCRIPTION
	The coreup utility enables all CPU cores on the machine.

	The coredown utility disables all CPU cores on the machine

	getting stuck) when more than one CPU core is online.

OPTIONS

	count
		Enable the first count CPU cores and disable the rest.

EXIT STATUS
	If the coreup and coredown utility fails it will exit with one
	of the following statuses:

	0	Successful completion.

	1	An error occurred.

NOTES
	There is no difference between the coreup(1) and coredown(1)
	utilities when the count operand is specified.
