"Red Storm: The Next Supercomputer" (Ynet)

Recommended Posts

"The US Department of Defense is completing the development of the most powerful supercomputer in history, "Red Storm", which will begin operating in the coming months. The power of 41 trillion calculations per second will enable it to stand at the forefront of the global war on terror. The secret of his power: thousands of processors And technology developed in Herzliya "

41 trillion calculations per second- ?? How much does the most powerful home processor have? ::)

* " When it came time to choose the processors, Cray chose Opteron's processors , Although they were not yet available in the market at the same time. No less than 11,648 such processors will be used by the new supercomputer. The planners explained that they prefer the parallel calculation method within each processor , The 64 bit architecture of the company, and the technology known as HyperTransport, which allows each processor to transfer data to other processors as well. "

Mandrake lacks the level of EAL 5 + (only IBM MAINFRAME systems have such approval) and inside the computer and it is their computer perfect

Computer da In theory there are many other factors. 4 is a 3.2 processor. 800 is one million calculations per second. It is about the same. It is about 50000 less than the computer in question. Of course there are systems that do 2 operations per cycle. Multiply by multiplication then comes out having 3 Millard calculations so this "only" 1.6 times louder then 25000 processor Opterton X11502 will do "only" 50 trillion Triggers rather than 20.376 trillion and that without calculating a lot of factors that reduce efficiency

Now for something interesting we will compare the heat systems to AMD64 as TDP of 80W to PRESSCOT as 110W to handle 100W as 200BTU then to cool AMD64 processor need 160BTU and to cool PRESSCOT processor need 220BTU dual 11502 processors have 1840320BTU for cooling all AMD and 2530440BTU processors to cool Intel processors per air conditioner has Approximately 10000BTU (air conditioner of 2-2.5 hp) then need for Intel processors as 253.044 air conditioners and more of Need 184.032 Air Conditioners More SA savings I just read that they do use Linux Linux, respect, power and something you've forgotten and in my opinion the most important Israeli company is involved!

How is it suddenly connected? :)

It reminds me of the article on the graphic layout he bought USA with 400 Radon 9800 processors .....

Or that their army is starting to get a little bit of brains (and not like our eBay buyer if they buried an 7000 per unit) or that Bush bought a new expensive toy : Lol:

And I want too!

The 4 processor is 3.2 processor 800 XMUMX million calculations per second which is about the same as 50000 less than the computer in question. Of course, there are systems that do 2 operations per cycle (Intel) and there are those that do 3 per cycle (AMD) so you have to multiply by the multiplier then it comes out that there are 1.6 Millard calculations so it is "only" 25000 times stronger then 11502 processor Opteron X50 will do "only" 20.376 trillion Triggers rather than 40 trillion and that without calculating a lot of factors that reduce efficiency

You are confusing uOps with assembler commands.

Both the P4 and the K7 / 8 perform one command per cycle - in an ideal mode (ie, the requested information is in the CASH, the requested spaceline is not used, etc.).

What you're talking about is about practical performance on the ground.

Therefore, the frequency of a P4 or K7 / 8 processor is the theoretical figure for its performance - which is defined in the barmarkers of computers as RMax if I am not mistaken.

The P4 processor at 3.0GHZ has a theoretical GFLOP 3, the optron in 2.4GHZ (as used by this computer) has only theoretical GFLOP 2.4.

The point is, especially when you plug in many processors at the same time, meaning that AMD's preferred bass, which has real performance, is very far from that data. It is rare to reach 80% of theoretical performance even after running heavy optimizations for software.

True 64 bit processors such as Itanium perform two commands for a clock cycle, so it is comparable to P2GHZ on Itanium xNUMXGHZ, but it is practical in the architecture of itanium, which makes it much better (but still much less good than K1.5!)

editing:

Here is the PDF of Cray: http://www.lanl.gov/orgs/ccn/salishan2003/pdf/camp.pdf

The whole system is amazing, each computer connected via a special network connection to three other computers in a three-dimensional frame.

The latency of this thing is lower in communication between computers than a PC communicates with memory His.

And what a cute Hardisk (RAID), the array provides no less than 50GB / S bandwidth for writing to permanent storage!

Not really - 0.75 air conditioner hp provides approximately 7000-8000BTU

Air-conditioner 1 hp provides between 9000-11000 and hp.

2-2.5-KW conditioners provide approximately 18000-25000 hp - varies from manufacturer to manufacturer and model

Nitrogen cooling?

Nitrogen is quite common in refrigerating to a very low temperature,

Even though it seemed a bit too much to cool off a computer with the help of

Nitrogen that you just freeze it (literally I mean)

I have no idea why nitrogen is used for such things,

Perhaps because it is relatively easy to keep it at high pressure and by doing so

At a very low temperature?

Nitrogen is not so effective.

Once you remove it from the optimal conditions in which it is stored in its own storage tool, it dissolves into the air.

To maintain temperature over time you need to pump more and more nitrogen, or alternately grab your "wasted" nitrogen, return it to conditions of pressure (and cold) and then use it again.

Not exactly a very efficient system ....

The ideal material would be a material that would absorb heat in bulk and quickly and release that amount quickly.

Like the sky absorbs the heat and then loses it in a radiator, only in a higher capacity.
