Hi All,
We have HP DL380 Server with 48GB of DDR3/1333 MHz RAM, 4 1Gbps NIC
Ports, 1 External RAID Card, 1 Internal RAID Card and 2 Intel(R)
Xeon(R) CPU X5570 @ 2.93GHz used as an NFS storage server. Running
Ubuntu 9.10 2.6.31-14-server.
(The Storage is used as an NFS storage for more than 300VMs running
using Citrix XenServer)
For More info on the Hard ware configuration
http://h18000.www1.hp.com/products/quickspecs/12028_div/12028_div.html
With HTT enabled in BIOS i can see 16 CPU(0-15) as per cat /proc/cpuinfo.
The problem is all the interrupts are handled by CPU0, as per
/proc/interrupts including the timer interrupts.
And the value of /proc/irq default_smp_affinity is ffff.
Also for all the interrupts the smp_affinity is ffff.
What i believe is with these setting all the interrupts should be
handled by the First 8 CPUs in a Round robin Fashion.
Or in our case at worse by the first 4 cores (since HTT is enabled -
*not clear with this concept though some once please put some light
over here also for better understanding :-)* ).
Also i tried to edit the smp_affinity of an interrupt to a value 0004
to test that if the interrupt is handled by some other core. But i was
unable to edit this value in a running system i got the access denied
error so i can't do this.
Please help me in distributing the interrupts among the other cores of
my system which might increase some performance of my system.
let me know if you need some log of the system or some other info
about the system.
Hari

Mauro, list,
(please CC me in replies, I am not on the lkml list).
I am having a similar issue as:
http://lkml.indiana.edu/hypermail/linux/kernel/1006.3/01811.html
which has no responses.
My company is using an evaluation of dual 5645 xeon board with the 5520 chipset.
Attached is my kernel config.
We have 12 82580 intel (igb) nics, and their affinity is set to
0xffffffff, but I see all interrupts happening on cpu0:

That may be chipset dependent, I don't think all chipsets have the
ability to distribute the interrupts like that. Round-robin interrupt
distribution for a given handler isn't optimal for performance anyway
since it causes the relevant cache lines for the interrupt handler to
be ping-ponged between the different CPUs.

Please see the two attached examples.
Notice on the 5410 example how we start with the affinity set to 0xff,
and change it to 0xf0.
This should spread the interrupts over the last 4 cores of this quad
core - dual processor system.
Also notice on the 5645 example, with the same commands we start with
0xffffff and change to 0xfff000 to spread the interrupts over the last
12 cores, but only the first of the last twelve cores receive
interrupts.
This is the inconsistency I was trying to explain before.

What was the status of irqbalance daemon? Was it turned on? If it is
running, there is a chance that the interrupt count is within the
threshold limit and interrupts are not being routed to the other core.
Could you also try with increasing the interrupt load and see if the
distribution is happening among the cores?

We use spirent testcenter l2/l3 test equipment and pushed 100%
throughput with the same distribution. Nothing changed.
This isn't affecting just ethernet drivers. I have also seen the same
issues with hardware encryption devices and other hardware that gets a
software interrupt.

In the example that you have given, I could see just 7 interrupts after
15 seconds.
So thought of checking it. Let me try to see this problem locally.

Again, I can set a TxRx interrupt to a specific core and this works
fine, but when I try to set that same TxRx interrupt to a set of
cores/processors - interrupts only occur on the first core/processor
of the set.

As I mentioned before, I believe the behavior in this case is chipset
dependent, and potentially not something the kernel has control over.
In most cases distributing the same interrupt across multiple cores is
likely a bad idea in any case, unless the interrupt load is actually
so high that a single CPU can't handle it.

Can anyone confirm that this is how the 5520 and newer xeon chipsets
handle affinity?
I might be totally wrong, but I thought that RSS (Receive Side
Scaling, which is available on the 82576 network card in that 5645
xeon example) helps in that scenario?

It looks like that card gives you multiple interrupt vectors that can
be serviced independently by multiple CPUs. However, each interrupt
vector is likely to only be handled by one CPU at a time.
