I suspect Larry is actually right that uniprocessor and $smallnum CPUs
SMP performance will remain the most important, but I don't agree with
his reasoning:
Once true virtualisation becomes part of a mainstream microprocessor
architecture, we'll start to see a lot of small ISPs wanting to move 4
or so 1U servers on to a single, 1U SMP box. Server consolidation
saves money in many ways - physical LAN cabling is replaced by virtual
LANs, less network hardware such as switches is required, there is
less hardware to break, you can add a new Linux image in seconds using
spare capacity rather than going out and buying a new box.
Once the option of running a firewall, a hot spare firewall, a
customer webserver, a hot spare customer webserver, mail server,
backup mail server, and a few virtual machines for customers, all on a
1U box, why are you going to want to pay for seven or more Us in a
datacentre, plus extra network hardware?
You can do this today on Z/Series, but you need to consolidate a lot
of machines to make it financially viable. Once virtualisation is
available on cheaper hardware, everybody will want $bignum way SMP
boxes, but no Linux image will run on more than $smallnum virtual
CPUs.
John.

Which is exactly what Larry is advocating. Essencially, instead of having
one large image covering a large NUMA box, you have several images covering
each NUMA node (even if they're in the same box).

Right, that is indeed what I believe needs to happen. Instead of spreading
one kernel out over all the processors, run multiple kernels. Most of the
scaling problems go away. Not all if you want to share memory between
kernels but for what John was talking about that is not even needed.

Hi,
I've run into a wierd problem with 2.6.0-test4-mm4 on an SMP Xeon
550Mhz system. I was dd'ing some images to floppy and when I used a
bad floppy, it would read 17+0 blocks, write 16+0 blocks and then
hang. At this point, I couldn't use the keyboard at all, and I got an
error message about "lost serial connection to UPS", which is from
apcupsd, which I have talking over my Cyclades Cyclom-8y ISA serial
port card.
At this point, the load jumps to 1, nothing happes on the floppy
drive, and I can't input data to xterms. I can browse the web just
fine using the mouse inside Galeon, and other stuff runs just fine. I
can even cut'n'paste stuff from one xterm and have it run in another.
But the only way I've found to fix this is to reboot, which requires
an fsck of my disks, which takes a while. I'll see if I can re-create
this in more detail tonight while at home, and hopefully from a
console.
Strangley enough, Magic SysReq still seems to work, since that's how I
reboot. Logging out of Xwindows works, but then when I try to reboot
the system from gdm, it hangs at a blank screen.
Whee!
Here's my interrupts:

| Hi,
|
| I've run into a wierd problem with 2.6.0-test4-mm4 on an SMP Xeon
| 550Mhz system. I was dd'ing some images to floppy and when I used a
| bad floppy, it would read 17+0 blocks, write 16+0 blocks and then
| hang. At this point, I couldn't use the keyboard at all, and I got an
| error message about "lost serial connection to UPS", which is from
| apcupsd, which I have talking over my Cyclades Cyclom-8y ISA serial
| port card.
|
| At this point, the load jumps to 1, nothing happes on the floppy
| drive, and I can't input data to xterms. I can browse the web just
| fine using the mouse inside Galeon, and other stuff runs just fine. I
| can even cut'n'paste stuff from one xterm and have it run in another.
|
| But the only way I've found to fix this is to reboot, which requires
| an fsck of my disks, which takes a while. I'll see if I can re-create
| this in more detail tonight while at home, and hopefully from a
| console.
|
| Strangley enough, Magic SysReq still seems to work, since that's how I
| reboot. Logging out of Xwindows works, but then when I try to reboot
| the system from gdm, it hangs at a blank screen.
|
| Whee!

Yes, bad_flp_intr() has some problem(s). See
http://bugme.osdl.org/show_bug.cgi?id=1033 and
http://marc.theaimsgroup.com/?l=linux-kernel&m=105837886921297&w=2
It's on my long work list.

If you plan to run anything else on your firewall, and use the same
machine as a hot spare for itself, I don't want you as my ISP.
Reliability is expensive, and what you describe is known as a single
point of failure.
