kernel gives wrong values in /proc/loadavg #11

Closed HSTe closed 11 years ago

HSTe commented 11 years ago

There is something wrong in how it calculate the values. Even when cpu is idling it has a loadavg over 4

projectgus commented 11 years ago

The majority of this is fixed with commit b8a4b014ead3840271b00948b4970051b13e4ff2 (currently part of #15.) There were 4 IPU tasks running in uninterruptable sleep, thereby inflating the load average by 4.

The commit switches them to interruptible which I think is a harmless change unless the kernel decides to kill them, which is should probably be allowed to do anyhow.

That said, idle load averages are still high (0.5-0.7 sometimes when I'd expect close to 0.) I don't have an explanation for this, I think something with softirqs. Still, <1 is much better than >4. :)
