From 140 to 1,759,000,000,000,000

This semester I have been hammering away at two themes: Twitter and High-Performance Computing.

Twitter is a micro-blogging service that limits postings (i.e. tweets) to a maximum of 140 characters.

During November 02009, TOP500 issued its list of the world’s 500 fastest supercomputers and Jaguar was number at 1.759 petaflops (i.e. 1759 trillion floating-point operations per second).

The lecture notes for weeks 13 (02009.11.16) and 15 (02009.12.01) contained the following tweets.

The Global Language Monitor names “Twitter” the top word of 2009.

I’ve been telling students that I am in the process of learning about Twitter. For me, as of 02009.12.01, the power of Twitter is in who I follow.

President Obama visited China and he had Twitter on his mind.

“First of all, let me say that I have never used Twitter.”~Obama to Chinese

I don’t know why Obama had to let the Chinese in on the fact that had never tweeted.

“I’m a big supporter of not restricting Internet use, Internet access, other information technologies like Twitter.”~Obama to Chinese

Obama referred to Twitter as a form of “information technology” and these days I call this 21st century Informatics. In a nutshell, 21st century Informatics is supercomputer-based data processing.

Al Gore was the keynote speaker at the 21st annual SC conference. SC is an “international conference on High Performance Computing (HPC), networking, storage and analysis.”

At SC09, Al Gore says supercomputing can be killer app in climate change.

Gore believes high-performance computing systems, which include high-performance visualization systems, will help convince the world that climate change is a real problem. Gore might be wise to expect the unexpected.

“Supercomputing has given us the most powerful tool in the history of civilization.”~Al Gore at SC09

A bold statement by Gore and only time will tell if he is correct.

By the way, Steve Wozniak once said, “Never trust a computer you can’t throw out a window.”
