New Server Chip Niagara
* * Beatles-Beatles writes "Sun recently announced their latest release in server technology. The UltraSparc T1 processor, code-named Niagara, has eight computing engines on a single chip, with each core capable of handling up to four tasks at once." With this new processor Sun hopes to get a leg up on the competition. The Niagra chip is being billed as an "eco-friendly" chip because of its low power requirements. From the article: " [...] removing the world's Web servers and replacing them with half the number of UltraSparc T1-based systems would have the same effect on carbon dioxide emissions as planting 1 million trees."
What about all the real nasty chemicals that go into the manufacturing process of chips .. eg arsenic and acid !!!
Eight cores at four threads is 32 simultaneous threads. Nice, but what about memory bandwith? Each thread needs proper I/O if this is actually going to do any good... Anyone have any real info on this marchitecture?

You need at least a dozen concurrent threads or processes before you can make good use of this CPU's power. Certainly not a good idea for desktops. An excellent match for web servers. Other server-type workloads (e.g. database, file server) may need some tuning to make the best of this architecture.
Stop worrying about the risks of nuclear power and start worrying about the risks of not using nuclear power.
Right on.
To be pedantic, planting trees (unless it's done on soil that was used for industrial agriculture, which has pretty much giving up its carbon already), will generally cause a release of CO2 from the ground. Even once the forest becomes mature, the net release of CO2 is positive in many cases (especially if the land used to be grassland).
But assuming that is ignored, a million trees:
- Is nothing. Assuming they're Christmas trees, it's about a square kilometre. It's also about 1/100th of the annual harvest in the USA.
- Is meaningless. Tell me in megatonnes of CO2 or gigawatts how much this will save, and if it doesn't equal a megatonne/yr or gigawatt, then it is just a drop in the bucket. Probably less of an effect than eradicating all spyware (thus causing less PCs to be replaced by lazy or ignorant or rich PC owners).
For a lot of uses today, a swarm of processors like this makes more sense than driving one CPU hellishly fast so it can task-switch quick enough to get around to everything.
Sun traditionally has been very good at engineering the interconnects so I expect the actual throughput on this is pretty good.
Will be interesting to see how well this does.
Um, yeah, but given that your two most strenuous processes are using 4% and 2% of your CPU respectively, with your machine posting mighty load averages of 0.33, 0.30, 0.18, I think you can safely hold off on upgrading to an 8-core processor any time soon--unless some of those threads aren't sleeping fast enough for you :-)
