China claims supercomputer crown

 

China has claimed the top spot on the list of the world's supercomputers.

The title has gone to China's Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.
To reach such high speeds the machine draws on more than 7,000 graphics processors and 14,000 Intel chips.

Key Terms to Understand this Story

CPU speeds are dependent upon the type of instructions being executed: some are hard and some are easy.
FLOPS are hard and, in general, more meaningful than MIPS and MOPS.

The replace() method for Strings

Image by trailfan via Flickr

The replace() method searches for a match between a substring (or regular expression) and a string, and replaces the matched substring with a new substring. It searches the string on which it is called for matches.

If the g flag is set, the method replaces all matches in the string with the replacement string; otherwise it replaces only the first match it finds.

EXAMPLES

//replaces first match
//wasit a rat i saw
var s = 'was it a rat i saw'; alert(s.replace(/[ ]/, ''))

//replaces all matches
//wasitaratisaw
var s = 'was it a rat i saw'; alert(s.replace(/[ ]/g, ''))
