Computers to make eCabinets scream!!!
Okay, Kerry started this with his Cray XT4 tagline...
Here is the list of the 500 fastest computing sites in the world as of June 2007.
As you can see, Kerry's Cray (specs page) comes in second place to IBM's BlueGene/L (specs page).
The IBM uses 700 MHz PowerPC processors (65,536 of them!) and the Cray uses 2.6GHz AMD processors (11,706 of them!).
If you would like to buy your very own personal supercomputer, check this out: Tyan's 40 CPU Personal Supercomputer, very affordable at $20,000 (when compared to the prices of IBM and Cray ).

Thanks a lot Dan,
I traded off my Tandy TRS-80 to get this new Cray, I haven't even tried eCabinets on it and you are telling me I will have to upgrade. I think I am going to try upgrading the XT4 to its maximum of 120,000 processor cores before I junk it for the IBM.
Seriously, what started the Cray thing is that I ran across an article from 2000 when Phillips Petroleum purchased one of its Crays for finding new oil deposits. My sister has been employed by Phillips for around 25 years and her office was in the computer building at the time this 3.6 million dollar computer was installed. I hadn't purchased my first computer at that time and I couldn't see what the big deal was. This Cray had 136 675MHZ processors and 84G memory. As with all computers it is now considered small. I don't know if this has been replaced or not. Do Supercomputers become obsolete every two years?
I also found it interesting that Cray uses AMD Processors.

That was a real eye-opener on the processors, eh? Did you notice that the Cray and Tyan both run Linux? The Tyan will also run on Windows!!!
Also on the list at #8 is an array of Dell PowerEdge 1955 servers in a grid configuration.
The really interesting thing about these \"supercomputers\" is that most are arrays of computers interconnected by a really fast backbone (read \"internal network\"). Everyone thinks of a supercomputer as being a single computer but that is not the case. They have a \"controller\" that decides which node(s) will do the work. In software designed for multiprocessing, the controller will divide the work between as many nodes as possible to accomplish the task quicker. Each node has its own processors and memory and all share a disk storage array.
I don't think supercomputers become obsolete every two years like PCs simply because of the cost. Remember back when you got an 8MHz CPU, 64KB RAM and a 5MB disk drive for $3000 (~$7500 2007 dollars)? That PC wasn't obsolete in two years
Today's big obsolescence problem is of course of our own making. As soon as a computer is developed to meet the requirements of our software, we ask for more features in the software. When the features are added to the software, the hardware can't keep up, thus new hardware is developed, ad infinitum
Anyway, I hope everyone enjoyed this lighter look at the state of computing.

Dan,
I was reading up on the IBM BlueGene/L (Considering one for the office ) They mention that is can be scaled up to a performance equal to 3 or 4 petaflop.
What in the HE** is a petaflop? it sounds like something the dog might do in the back yard. Seriously who comes up with these words?

Bill,
I haven't heard of a petaflop. A teraflop or tflop is trillion calculations per second. That is a lot.
I googled it.
\"A petaflop is a measure of a computer s processing speed and can be expressed as a thousand trillion floating point operations per second.\"
I think most PCs are still measured in gigaflops.

From Webopedia:
In physics and mathematics, peta- (symbol: P) is a prefix in the SI (system of units) denoting 10^15, or 1 000 000 000 000 000. For example:
1 petametre = 10^15 metres
1 petasecond = 10^15 seconds
Adopted in 1975, it comes from the Greek πέντε, meaning five, because it is equal to 10005. It is based on the model of tera- (from Greek τέρας = 'monster', but looking like tetra- from the Greek for \"four\" with a letter missing, and so peta-, coming from penta-, omits the third letter, n.
In computer science peta- can sometimes mean 1 125 899 906 842 624 (10245 or 250), instead of 1 000 000 000 000 000, especially when used to prefix the byte, giving a petabyte. To resolve this ambiguity, the term pebibyte has been suggested to mean 250 bytes. However, this term is not yet widely used.
See table for other \"useful\" terms of scientific measurement
EDIT: changed occurances of 1015 to 10^15
From Wikipedia:A petaflop is the ability of a computer to do one quadrillion floating point operations per second (FLOPS.) Additionally, a petaflop can be measured as “one thousand teraflops”. A petaflop computer would require a massive number of computers working in parallel on the same problem. Applications might include real-time nuclear magnetic resonance imaging during surgery or even astrophysical simulation.

DUH!!!

DUH !!!! on me again... I should have looked at the attachment, right? I kept scratching my head, trying to figure out the 1015 part - and the ONLY 1015 thing I know is the onion, in Texas. The sweetest onions I have ever eaten, and almost as sweet as apples when eaten raw.
