The new systems and "eco-responsibility" Okay, we got this new buzzword to attach to computer systems: eco responsibility.
Hurm, it may sound a little strange to attach that word to something
meant to stay running 24/7 regardless of whether it's doing anything
useful or not. Leaving a server running full time is kind of like
leaving a lightbulb on all day while you're at work. That
electricity got wasted, you just wasted some money, and the fossil fuel
burned to provide that electricity still poisined the air even though
it was pure waste.
On the other hand, if you're going to have a machine turned on and
doing something it is ecologically responsible to study how to optimize
the energy use of that machine.
And, it's not just ecologically responsible, but the power savings will contribute to the corporate bottom line in lower costs.
And just why is this important? Let me spin your mind back a few
years -- California, late 90's, the .COM is booming before the
.BUST. But one of the strange things happening is the rolling
blackout phenomenon. The newspapers are full of stories about the
power situation. It wasn't until later that we learned that GW
Bush's buddies at Enron were ripping off California.
What instead the newspaper discussed was how with the rise of "server
farms" the power needs density metrics the electric power industry had
lived by were going out the window. A server farm is a dense
packing of servers into a building, with air conditioning out the wazoo
to keep it all from melting down. The power needs of a server
farm tended to equal the needs of small towns, in just one
building. THIS, the newspapers claimed, was the source of the
blackouts, the rapid rise in power demands.
Clearly the hotter each individual computer runs, the worse the problem
is. Each hot computer heats the room, meaning more air
conditioning, and more air conditioning means more electricity required
for cooling. It doesn't take an air conditioning specialist to
understand that.
On the other hand if the servers run cool, not as much air conditioning
is needed, meaning less power than the hot computers. That to me,
as a part-time environmentalist, is the
gold of the Niagra announcement. That the chip has all those
threads and can so gracefully interleave thread execution is great and
I'm sure will mean for a huge jump in system performance. But to
also do so with lower direct power consumption, as well as lower
indirect power consumption (air conditioning) is the icing on the cake.
See, the fossil fuels that get burned today to create the power we use
- that stuff isn't going to be replaced any time soon. When the
fossil fuels run out "we", the modern societies, had better have
developed alternative energy technologies that makes sense (and, no,
nuke power just doesn't make sense). If we don't do so, well, let
me remind you of the Mad Max movies.
In fact it appears the world is a lot closer to the oil peak, and
perhaps the natural gas peak, than the world's people understand.
I think there's a lot of denial going on, with the SUV problem being a
symptom of that denial, and that stupid illegal war in Iraq being
another symptom. (Not to mention the threat to invade Syria
and/or Iran). In denial, "we" the modern societies would continue
to wastefully assume the fossil fuel power industries can supply us
with power forever, and continue to stupidly refuse to do anything
about it. Witness our idiot President and the oil-laden National
Energy Policy.
I for one am glad to work for a company that wants to do something positive about this issue.
There's some web pages
to help you understand what the official line on this is. The
official line is obviously not going to be quite as rabid as I am on
this issue.
