The exponential growth of computing performance is very noticeable when you examine how the performance of the world’s most powerful computer systems, the supercomputers, has changed over time.

To give you an idea of how rapidly performance has been growing, the top supercomputer in 2000 delivered more performance than the entire top 500 supercomputers combined in 1995, just five years earlier. Comparing 2005 with 2000 you see the same thing, and 2010 with 2005.

Top supercomputer performance over time
Here is the performance of the fastest supercomputer in the world, the past 15 years:

Top in 2010: 2.57 petaflops
Top in 2005: 280.6 teraflops
Top in 2000: 4.94 teraflops
Top in 1995: 170 gigaflops
If we set the fastest supercomputer in 1995 as the baseline:

The top supercomputer in 2000 was 19 times faster.
The top supercomputer in 2005 was 1,650 times faster.
The top supercomputer in 2010 was 15,100 times faster.
Or, illustrated with a chart:



We could have used a logarithmic scale to make the smaller values easier to see, but we wanted to illustrate the sheer difference in scale. The bars for 1995 and 2000 aren’t even a pixel wide.

If you wonder why we didn’t go farther back than 1995, it’s because the TOP500 Project didn’t start tracking the global supercomputing performance until 1993.

From billions to trillions to quadrillions
In 2010, we measure the performance of the fastest supercomputers in petaflops (quadrillions of operations per second). In 1995, we used gigaflops (billions of operations per second). We are now using a scale a million times larger than we did 15 years ago.

That’s progress.

Back to the games, boys and girls.

Excellent blog and good picture. Does Cray have anything bigger ?

So... Google's spiders crawl through the internet and cache EVERY page they can get to. Im curious to know if that means that Google pretty much has the internet downloaded? for the most part anyways..

I would almost be willing to bet that Google would have a form of super computer for themselves, It would make good business sense for them. WRONG ANSWER

SEO 101: How Google Crawls, Indexes, and Serves the Web by Chris Wilson
in Internet / Web Hosting (submitted 2010-11-20)

Ver wondered how Google can instantly summon the answer to just about every question you've ever had? We've all used the popular search engine, but what are the mechanics behind this program we've all come to depend on so much?
To put it as simple as possible, Google SEO is like the worlds fastest librarian in the world's largest library, and not only is she fast, she knows where every book is by memory, and not only that, she has the 10 best books for your search, in her pocket� It doesn't get much faster than that.
Basically, every time you do a search, Google analyzes your criterion and pulls up a list of the most relevant sites it has that relate to the key phrase or words you put in.
Best Seo Company have three primary processes which work together to provide you with results,
Fortunately for us, the same three processes are also used in determining your sites ranking.
â• ¢ Crawling: Submit your site to Google, they'll crawl it, and pick out keywords that define your site.
â• ¢ Indexing: Is your Site index able? Do you meet the minimum requirements?
â• ¢ Serving: Does your site provide relevant information that users will find useful?
Crawling
Crawling is a term used to describe the Googlebot's scanning procedures; the Googlebot scans and discovers websites as well as re-scans updated websites.
The process begins with an inventory of URLs and site maps, compiled from earlier crawls. When the Googlebot visits of each the sites it searches for links on each page and adds them to the next list of pages to scan. Updated sites, new sites, and dead links are recorded and later used to update the Google search index. Google utilizes a large group of computers to run Googlebot, (Google's Primary Scanning Spider) Googlebot crawls Billions upon Billions of web pages in order staying current. Specially formulated programs to determine which sites need to be crawled and how often.
Indexing
Googlebot uses an extremely complex system to scan each page, every word along with its placement on the page is noted and this in turn determines its place in the search rankings. Titles and Key attributes such as sub headings, and Meta headings are all taken into context and have a larger impact on placement.
Serving results
When someone conducts a search, Google quickly compiles a list of results ranked in relevancy to the query. Relevancy of the sites are determined by over 150 factors! One of the most important determining factors would be your sites page rank. To earn a higher page rank your site must have several back-links, the more links to your page, the higher ranking your site will earn. However, not all links are of equivalent value, if you managed to get CNN to link to your site, or the New York Times for instance, you will earn more points than say, your friend Steve's blog, who has an annual hit count of about 40. If you really want your site to have a high ranking, it is essential that Google is allowed to Crawl and index your site. Google's Webmaster Guidelines outline important guidelines that you should stick to if you want your site to do well.
