penable, pdisable

NAME

penable, pdisable - switch strand on/off

SYNOPSIS

DESCRIPTION

penable enables a collection of cpus for execution. This collection is a set of cpus, specified through either the -cpu flag or, alternatively cpu-mask, which is a bitmask corresponding to cpus numbered 63 through 0, most significant bit to least.

If no argument is given, penable will list all enabled strands.

pdisable disables a collection of cpus. This collection is specified using the -cpu or a cpu mask as with penable. A disabled strand is simply stalled for an infinite amount of time. Take care that least one cpu is enabled to guarantee forward progress.

If no argument is given, pdisable will list all disabled strands.

RETURN VALUES

None.
