Writing the Fastest Code, by Hand, for Fun: A Human Computer Keeps Speeding Up Chips
The New York Times ^ | November 28, 2005 | JOHN MARKOFF

SEATTLE - There was a time long ago when the word "computer" was a job description referring to the humans who performed the tedious mathematical calculations for huge military and engineering projects.

It is in the same sense that Kazushige Goto's business card says simply "high performance computing."

Mr. Goto, who is 37, might even be called the John Henry of the information age.

But instead of competing against a steam drill, Mr. Goto, a research associate at the Texas Advanced Computing Center at the University of Texas at Austin, has bested the work of a powerful automated system and entire teams of software developers in producing programs that run the world's fastest supercomputers.

He has done it alone at his keyboard the old-fashioned way - by writing code that reorders, one at a time, the instructions given to microprocessor chips.

At one point recently, Mr. Goto's software - collections of programs called subroutines - dominated the rarefied machines competing for the title of the world's fastest supercomputer. In 2003 his handmade code was used by 7 of the 10 fastest supercomputers. (The Japanese Earth Simulator, which was then the world's fastest machine, however, did not use his software.)

In the most recent ranking of supercomputers, I.B.M.

machines overtook a number of supercomputers using Mr. Goto's software to capture the top three spots in the fastest computer rankings. Still, the Goto Basic Linear Algebra Subroutines, or BLAS, as his programs are known, were used by 4 of the world's 11 fastest computers.

Mr. Goto has become a legend in the supercomputing community because of his solitary crusade. And he shows no signs of flagging in the contest to wring every ounce of computing speed from the world's fastest microprocessor chips.

Isn't that a do nothing loop?

"Isn't that a do nothing loop?"
10 goto 10
Probably yes. But when one thinks about it a moment, it does do something. It re-iteratively goes to statement 10. Man am I a genius. ha ha.
