hackbench regression due to commit 9dfc6e68bfe6e

[Alex Shi]

The hackbench benchmark dropped about 3~7% on our 2 sockets NHM machine
on 34-rc1 kernel. We find it is due to commit 9dfc6e68bfe6e, 

commit 9dfc6e68bfe6ee452efb1a4e9ca26a9007f2b864

    SLUB: Use this_cpu operations in slub
    
The hackbench is prepared hundreds pair of processes/threads. And each
of pair of processes consists of a receiver and a sender. After all
pairs created and ready with a few memory block (by malloc), hackbench
let the sender do appointed times sending to receiver via socket, then
wait all pairs finished. The total sending running time is the indicator
of this benchmark. The less the better.  
The socket send/receiver generate lots of slub alloc/free. slabinfo
command show the following slub get huge increase from about 81412344 to
141412497, after command "backbench 150 thread 1000" running.

Name                   Objects      Alloc       Free   %Fast Fallb O
:t-0001024                 870  141412497  141412132  94   1     0 3
:t-0000256                1607  141225312  141224177  94   1     0 1 


Via perf tool I collected the L1 data cache miss info of comamnd:
"./hackbench 150 thread 100"

On 33-rc1, about 1303976612 time L1 Dcache missing

On 9dfc6, about 1360574760 times L1 Dcache missing

I also disassemble the mm/built.o file, but seems no special change.

The number of frees is different? From 81 mio to 141 mio? Are you sure it
was the same load?

I hope this is the same load?

What debugging options did you use? We are now using per cpu operations in
the hot paths. Enabling debugging for per cpu ops could decrease your
performance now. Have a look at a dissassembly of kfree() to verify that
there is no instrumentation.

The slub free number has similar increase, the following is the data
before testing:
name                   Objects      Alloc       Free   %Fast Fallb Onn
:t-0001024                 855   81412344   81411981  93   1     0 3
:t-0000256                1540   81224970   81223835  93   1     0 1

I am sure there is no effective task running when I do testing. 

Just for this info, CONFIG_SLUB_STATS enabled.

for the same load parameter: ./hackbench 150 thread 1000
on 33-rc1, about 10649258360 times L1 Dcache missing
on 9dfc6, about 11061002507 times L1 Dcahce missing

For this this info, without CONFIG_SLUB_STATS and slub_debug is close.

Basically, slub_debug never opened in booting, some SLUB related kernel
config is here:
CONFIG_SLUB_DEBUG=y
CONFIG_SLUB=y
#CONFIG_SLUB_DEBUG_ON is not set

I just dissemble kfree, but whether the KMEMTRACE enabled or not, the
trace_kfree code stay in kfree function, and in my testing the debugfs
are not mounted.

Christoph,

I suspect the moving of place of cpu_slab in kmem_cache causes the new cache
miss. But when I move it to the tail of the structure, kernel always panic when
booting. Perhaps there is another potential bug?

Why would that cause an additional cache miss?


The node array is following at the end of the structure. If you want to
move it down then it needs to be placed before the node field.

Thanks. The moving cpu_slab to tail doesn't improve it. 

I used perf to collect statistics. Only data cache miss has a little difference.
My testing command on my 2 socket machine:
#hackbench 100 process 20000

With 2.6.33, it takes for about 96 seconds while 2.6.34-rc2 (or the latest tip tree)
takes for about 101 seconds.

perf shows some functions around SLUB have more cpu utilization, while some other
SLUB functions have less cpu utilization.

Hmnmmm... The dynamic percpu areas use page tables and that data is used
in the fast path. Maybe the high thread count causes tlb trashing?

Hmm indeed. I don't see anything particularly funny in the SLUB percpu
conversion so maybe this is a more issue with the new percpu
allocator?

By default, percpu allocator embeds the first chunk in the kernel
linear mapping and accesses there shouldn't involve any TLB overhead.
>From the second chunk on, they're mapped page-by-page into vmalloc
area.  This can be updated to use larger page mapping but 2M page
per-cpu is pretty large and the trade off hasn't been right yet.

The amount reserved for dynamic allocation in the first chunk is
determined by PERCPU_DYNAMIC_RESERVE constant in
include/linux/percpu.h.  It's currently 20k on 64bit machines and 12k
on 32bit.  The intention was to size this such that most common stuff
is allocated from this area.  The 20k and 12k are numbers that I
pulled out of my ass :-) with the custom config I used.  Now that more
stuff has been converted to dynamic percpu, it's quite possible that
the area is too small.  Can you please try to increase the size of the
area (say 2 or 4 times) and see whether the performance regression
goes away?

Thanks.

Thanks. I tried 2 and 4 times and didn't see much improvement.
I checked /proc/vamallocinfo and it doesn't have item of pcpu_get_vm_areas
when I use 4 times of PERCPU_DYNAMIC_RESERVE.

I used perf to collect dtlb misses and LLC misses. dtlb miss data is not
stable. Sometimes, we have a bigger dtlb miss, but get a better result.

LLC misses data are more stable. Only LLC-load-misses is the clear sign now.
LLC-store-misses has no big difference.

LLC-load-miss is exactly what condition?

The cacheline environment in the hotpath should only include the following
cache lines (without debugging and counters):

1. The first cacheline from the kmem_cache structure

(This is different from the sitation before the 2.6.34 changes. Earlier
some critical values (object length etc) where available
from the kmem_cache_cpu structure.  The cacheline containing the percpu
structure array was needed to determome the kmem_cache_cpu address!)

2. The first cacheline from kmem_cache_cpu

3. The first cacheline of the data object (free pointer)

And in case of a kfree/ kmem_cache_free:

4. Cacheline that contains the page struct of the page the object resides
in.

Can you post the .config you are using and the bootup messages?

We cannot reproduce the issue here. Our tests here (dual quad dell) show a
performance increase in hackbench instead.

Well, your config might be very different... and hackbench results can
vary by 10% on same machine, same kernel.

This is not a reliable bench, because af_unix is not prepared to get
such a lazy workload.

We really should warn people about this.

booting with slub_min_order=3 do change hackbench results for example ;)

All writers can compete on spinlock for a target UNIX socket, we spend _lot_ of time spinning.

If we _really_ want to speedup hackbench, we would have to change unix_state_lock()
to use a non spinning locking primitive (aka lock_sock()), and slowdown normal path.

I don't know. I just said it's a clear sign. Otherwise, there is no clear sign.
The function statistics collected by perf with event llc-load-misses are very
scattered.

I agree with your analysis, but we still have no answer.

Pls. see the 2 attachment.

CONFIG_SLUB_STATS has no big impact on results.

Re: hackbench regression due to commit 9dfc6e68bfe6e

I run hackbench on many machines. The regression exists on Nehalem machine
(dual sockets, 2*4*2 logical cpu) and a tigerton (4 socket, 4*4 logical cpu)
machines. I tried it on a dual quad core2 machine and it does like what you said.

The regression also exists on 2 new-generation Nehalem (dual socket 2*6*2 logical cpu)
machines.

It seems hyperthreading cpu has more chances to trigger it.

Thanks. I also found that. Normally, my script runs hackbench for 3 times and
gets an average value. To decrease the variation, I use 
'./hackbench 100 process 200000' to get a more stable result.

By default, slub_min_order=3 on my Nehalem machines. I also tried different
larger slub_min_order and didn't find help.

Please check values of /proc/sys/net/core/rmem_default
and /proc/sys/net/core/wmem_default on your machines.

Their values can also change hackbench results, because increasing
wmem_default allows af_unix senders to consume much more skbs and stress
slab allocators (__slab_free), way beyond slub_min_order can tune them.

When 2000 senders are running (and 2000 receivers), we might consume
something like 2000 * 100.000 bytes of kernel memory for skbs. TLB
trashing is expected, because all these skbs can span many 2MB pages.
Maybe some node imbalance happens too.



You could try to boot your machine with less ram per node and check :

# cat /proc/buddyinfo 
Node 0, zone      DMA      2      1      2      2      1      1      1      0      1      1      3 
Node 0, zone    DMA32    219    298    143    584    145     57     44     41     31     26    517 
Node 1, zone    DMA32      4      1     17      1      0      3      2      2      2      2    123 
Node 1, zone   Normal    126    169     83      8      7      5     59     59     49     28    459 


One experiment on your Nehalem machine would be to change hackbench so
that each group (20 senders/ 20 receivers) run on a particular NUMA
node.

It's a good pointer. rmem_default and wmem_default are about 116k on my machine.
I changed them to 52K and it seems there is no improvement.

I expect process scheduler to work well in scheduling different groups
to different nodes.

I suspected dynamic percpu data didn't take care of NUMA, but kernel dump shows
it does take care of NUMA.

hackbench allocates all unix sockets on one single node, then
forks/spans its children.

Thats huge node imbalance.

All sockets structures (where all _hot_ locks reside) are on a single node.

Btw, you might want to try out "perf record -g" and "perf report 
--callchain fractal,5" to get a better view of where we're spending 
time. Perhaps you can spot the difference with that more easily.

Lets stop fiddling with kernel command line parameters for these test.
Leave as default. That is how I tested.

Seems that the overhead of __kmalloc_node_track_caller was increased. The
function inlines slab_alloc().

I wonder if this is not related to the kmem_cache_cpu structure straggling
cache line boundaries under some conditions. On 2.6.33 the kmem_cache_cpu
structure was larger and therefore tight packing resulted in different
alignment.

Could you see how the following patch affects the results. It attempts to
increase the size of kmem_cache_cpu to a power of 2 bytes. There is also
the potential that other per cpu fetches to neighboring objects affect the
situation. We could cacheline align the whole thing.

Would __cacheline_aligned_in_smp do the trick here?

Oh, sorry, I think it's actually '____cacheline_aligned_in_smp' (with 
four underscores) for per-cpu data. Confusing...

This is allocated via the percpu allocator. We could specify cacheline
alignment there but that would reduce the density. You basically need 4
words for a kmem_cache_cpu structure. A number of those fit into one 64
byte cacheline.

This does not particulary help to clarify the situation since we are
dealing with data that can either be allocated via the percpu allocator or
be statically present (kmalloc bootstrap situation).

Do we have a user program to check actual L1 cache size of a machine ?

I remember my HP blades have many BIOS options, I would like to make
sure they are properly set.

If there is no, it's easy to write it as kernel exports the cache stat by
/sys/devices/system/cpu/cpuXXX/cache/indexXXX/

If run individually, the tests results are more what we would expect
(slow), but if machine runs the two set of process concurrently, each
group runs much faster...

BTW, I just discovered (thanks to the function graph tracer, woo hoo!)
that loopback TCP packets get fully checksum validated on receive.

I'm trying to figure out why skb->ip_summed ends up being
CHECKSUM_NONE in tcp_v4_rcv() even though it gets set to
CHECKSUM_PARTIAL in tcp_sendmsg().

I wonder how much this accounts for some of the hackbench
oddities... and other regressions in loopback tests we've seen.
:-)

Just FYI...

I tested the patch against 2.6.33+9dfc6e68bfe6e and it seems it doesn't help.

I dumped percpu allocation info when booting kernel and didn't find clear sign.

Ok, it looks like it's only ACK packets that have this problem,
but still :-)

It's weird that we have a special ip_dev_loopback_xmit() for for
ip_mc_output() NF_HOOK()s, which forces skb->ip_summed to
CHECKSUM_UNNECESSARY, but the actual normal loopback xmit doesn't
do that...

Thanks !

But hackbench is a af_unix benchmark, so loopback stuff is not used that
much :)

If there are 2 nodes in the machine, processes on node 0 will contact MCH of
node 1 to access memory of node 1. I suspect the MCH of node 1 might enter
a power-saving mode when all the cpus of node 1 are free. So the transactions
from MCH 1 to MCH 0 has a larger latency.

How do the cpus map to the nodes? cpu 0 and 1 both on the same node?
