I've recently seen a Presentation on the issues around exascale. The end result... EVERYTHING must fundamentally change. The power requirements would alone swallow the needs of a small town. Even DDR4's bandwidth would be a second rate solution. The scheduling requirement across the hundreds of thousands of processors could consume the system alone, much less allow it to work. Only one of the supercomputing giants is actually building systems (for five years out from now) that will scale out to past 5 petaflops and Sandia is thinking about 1,000 petaflops.
The linux weenies might as well forget it because there's no way in hell that linux could ever run a box at Exascale. The hardware alone will be more than 12 years out.
Uuuhh...... what you don't realize is that this is NOT a Linux project. This platform will be running AIX and GPFS. Insiders within High Performance Computing are seeing what the commercial side of the world has known. At the end of the day, Linux isn't cheaper than any commercially available solution. Sure admins ARE cheaper, the hardware is cheaper, but at the end of the day, HPC Linux solutions CAN compete with IBM's AIX solution only when running ONE program through the stack across the entire cluster. This is fine for sites which have one user running one program across the entire cluster (such as the TOP500 linpack.) But the average site has many users scheduling many different workloads across many different groups of nodes. These sites are seeing a sharp contrast between Linux and AIX.
In corporate America, personality will make and break a team of any kind. Your personality, how it fits with other members of the team, etc adds to the dynamic of the team you join.
Believe me, after 14 years in IT, I've seen great combinations of personalities and bloody awful combinations. The bad ones may have had all "A" players who each had issues with working with others.
If you don't like this concept.... tough.... GROW UP.... Until then, grab your Mountain Dew and go back to your closet and churn out code for "mom and pops" for $25/hour who don't give a crap who you are.
When you're ready for the big leagues.... chop off your freakin' pony tail, tuck in your shirt, shave, apply some makeup to the tattoo on your neck, and put on a damn suit for your interview. Pucker-up by the way.... it's called being polite and diplomatic.
Unless of course you're interviewing in the valley somewhere, in which case.... crawl out of bed, shake your hair into a ball of fuzz and you should be set.
Point #1 - Nearly every computer system (all government computers) have a warning on their login screens telling you that it is a violation of law to gain unauthorized access.
Point #2 - They would seize computers to look for information that was saved on the computers. Reporters in the "drive-by" media think they are invincible. Freedom of the press doesn't extend to breaking the law. Mere access from one of the PCs would not prove that the coroner didn't happen to be there using the computers. Having saved information would make it easier to link the reporters to the breach.
Soldiers in the military don't have to follow unlawful orders. The question is more a clash of cultures. Cultures define what is moral and the Chinese believe this is a moral order.
Yahoo, as an American company, walks a fine line. As an American company, it should "tow the party line" on persecution of political dissidents. I'm sure they already have to act with Mainland China as though Taiwan doesn't exist (or is rouge state.) As any international organization weaves into the mainstream, they will assuredly have problems like this.

Little boys with their little Intel/AMD toys..... Do any of you have any idea about Power architecture is and where its going. IBM is generations ahead of the competition in performance. Sun's pathetic showing this week with their latest offering was laughable. It's expensive and yes it runs AIX but Power5 systems ROCK.
Their are two classes of Unix platforms: Enterprise Class and Desktop class. If it ain't Power or SPARC, it ain't on my list for customers (and those I have in the Fortune 10, won't even seriously consider Linux for big apps, their relegated to utility functions.) PC geeks for too long shout til their lungs are bloody and yet, they'll never get the "play they want" in the big leagues.
If you haven't seriously checked into Power5 and AIX (and yes something deeper than running SMIT.) If you can't run a system without menu's and GUI's, then limp your lame butt back to Windows.

Ever heard of Power5 processors for AIX? Not hard to beat FP performance of Intel processors.
