Japanese Researchers Calculate pi To 10 Trillion Digits

And the impressive feat of the day goes to these guys for calculating pi to ten trillion digits (and it only took 371 days to do it). eek!

Due to the size of this computation, a tremendous amount of memory was needed: Roughly 44 TB* of disk was needed to perform the computation. Another 7.6 TB of disk was needed to store the compressed output of decimal and hexadecimal digits. If the digits were stored in an uncompressed ascii text file, the combined size of the decimal and hexadecimal digits would be 16.6 TB.
