Gyarados OS is infamously known for its fierce temper and wanton destructive tendencies. Once it has worked itself into a frenzy, it will not calm until everything around it is destroyed—this tendency is attributed to the dramatic structural changes its brain undergoes during evolution. It seems attracted to violence, although this Pokémon is very rarely seen in the wild. During times of human conflict Gyarados are said to appear, burning entire cities down to the ground.

Sounds like Microsoft to me :D ]]>Sep 29th 2009 7:48PMhttp://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/http://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/
Obviously you've had a bad day, first Microsoft announces an awesome looking tablet that clearly blows any apple tablet rumors out of the water. Then we get this annoucement of OS research being done. Apple fanboi apparently has his panties all in a bunch over all the good Microsoft annoucements today.]]>Sep 29th 2009 8:39PMhttp://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/http://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/

I love how windows mobile can multitask, and is very open to the point where you can pretty much use any programs and applications you please. There are just a couple drawbacks I would like adressed.

You're an idiot, you're blaming the Silverlight technology for the buffer problem? God, you are dumb, don't you think that the geniuses at Netflix are the ones that actually MADE the movie player you're using? God, go bash MS somewhere where you know what the fuck you're talking about.

And about the Snow Leopard comment, I'm sure glad MS doesn't make me press a key combination to actually use 64bit.

Anyway!

Garp is right.

You reach a point of saturation eventually where adding more cores only improves your performance by a marginal amount, so you get less out of it than you put into it (performance vs dollars) beyond a certain threshold.

Joseph L. Flatley's statement was incorrect though, at least totally inaccurate if not altogether incorrect. ]]>Sep 29th 2009 11:29PMhttp://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/http://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/
Now a lot of applications are Threaded processes running on seperate cores accessing the same memory, but again you have an extra layer to make sure that the memory is in a proper state when each thread is working on it (thread a isn't working on data while thread b is waiting for the result, or worse using out of date data), and that is not a completely insignificant overhead.

The article is short on details on what this new approach gets you. Besides now having to work in the small memory space in cache. I can't believe they think message passing will be faster than shared memory. Where you going to store the message? This sounds like it will require new thinking in application development, at a time when programs are just starting to get more threaded.]]>Sep 29th 2009 11:56PMhttp://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/http://www.engadget.com/2009/09/29/microsoft-unveils-barrelfish-multi-core-optimized-os/
I believe that the idea with barrelfish is two accomplish exactly what you are saying when you said "You get great improvement in speed (almost double) if you can run seperate processes on each core that deal with completely different memory", You are right the article is short on details but don't be afraid to explore, Look what I found.

"Barrelfish is an instance of a multikernel operating system.
In such an OS, every core hosts one kernel, called the CPU driver in Barrelfish.
All kernels are essentially independent. State is not shared but replicated as
needed among the different cores."

that only kinda makes since to me but you may understand it better, There's much more... here

"With current operating systems, as the number of cores increases performance decreases"

That's just not true. More cores = better performance, to a certain point.
