[refer http://marc.info/?l=linux-kernel&m=118474574807055 for complete report of this bug] Ingo, Dhaval tracked the root cause of this problem to be in cfs (btw cfs patches weren't git-bisect safe). Basically, "make -s -j" workload hanged the machine, leading to lot of OOM killings. This was on a 8-cpu machine with no swap space configured and 4GB RAM. The same workload works "fine" (runs to completion) on 2.6.22. I played with the scheduler tunables a bit and found that the problem goes away if I set sched_granularity_ns to 100ms (default value 32ms). So my theory is this: 32ms preemption granularity is too low value for any compile thread to make "usefull" progress. As a result of this rapid context switch, job retiral rate slows down compared to job arrival rate. This builds up job pressure on the system very quickly (than may have happened with 100ms default granularity_ns or 2.6.22 kernel), leading to OOM killings (and hang). >From a user perspective, who is running with default granularity_ns value, this may be seen as a regression. Perhaps, these new tunables in cfs are something for users to become used to and tune it to approp setting for their system. It would have been nice for kernel to auto-tune the settings based on workload, but I guess that's harder. -- Regards, vatsa ^ permalink raw reply [flat|nested] 10+ messages in thread

The same workload works "fine" (runs to > completion) on 2.6.22. while i agree that the 32msec was too low, i think the problem is that "make -s -j" is a workload that has no guarantee of "success" on that system. The box does not have enough RAM to service it and does not have enough swap to survive it. In make -j, jobs are started without any throttling whatsoever. _Any_ control mechanism within the kernel can act as an "accidental throttle": for example IO could artificially slow it down to reduce job rate and keep RAM usage below the critical level. Or a kernel bug could cause tasks to be delayed and thus let the make -j "succeed". Or some bad kernel inefficiency in sys_fork() could have this effect too. It is very important that we dont look at every random number that a system can produce as a "benchmark", we really have to consider what happens behind it. > I played with the scheduler tunables a bit and found that the problem > goes away if I set sched_granularity_ns to 100ms (default value 32ms). yep - 32msecs was too low, please try -rc1 too: i've increased the granularity limit so it should be larger than 32ms. Reduce CONFIG_HZ as well if you are on a more server-type system. > So my theory is this: 32ms preemption granularity is too low value for > any compile thread to make "usefull" progress.

By increasing the granularity the timings change - one can imagine workloads where _reducing_ the granularity would result in an effective throttling of the workload. I'm sure a workload could be constructed on the old scheduler too where its 100 msecs isnt enough either, only 200msecs would help. That thinking never ends - you cannot tune non-throttled workloads. We've got to be really careful about this. Ingo ^ permalink raw reply [flat|nested] 10+ messages in thread
