package gomaxprocs

import "gvisor.dev/gvisor/pkg/gomaxprocs"

Package gomaxprocs synchronizes adjustments to GOMAXPROCS. When this package is active (i.e. after the first call to SetBase), it sets the value of GOMAXPROCS to a "base" value (which should be set by a single goroutine, without races) plus a non-negative "temporary" value (which may be concurrently increased or decreased by multiple goroutines).

Note that changing GOMAXPROCS stops the world, so callers should adjust GOMAXPROCS infrequently.

TODO: Add gomaxprocs.Get() and check that other gVisor packages don't call runtime.GOMAXPROCS() at all.

Functions ¶

func Add ¶

func Add(n int)

Add adds n temporary GOMAXPROCS. n may be negative; callers should call Add with negative n to remove temporary GOMAXPROCS when they are no longer needed.

func SetBase ¶

func SetBase(n int)

SetBase sets base GOMAXPROCS.
