For the first time mathematicians were able to calculate the Pi constant with 10 trillion decimal digits.
Ten trillion would represent a 1 with 13 zeros. If you were to print that number on paper, you would need about 2.87 billion sheets, based on a standard configuration of about 3500 digits per sheet. Such a stack of paper would reach a height of 21.4 miles.
According to an unofficial announcement the calculation of the 10 trillion digits, it took 371 days and an additional 45 hours to verify on a system equipped with two Intel Xeon X5680 processors, 96 GB of memory and 24 2 TB hard drives. Only the first 5 trillion are offered for download as decimals via five separate downloads totaling 1.91 TB at this time.
The record of 10 trillion records doubles the previous record of 5 trillion digits, which was posted in August of this year.

fancarolina I wonder if this scales linearly, would adding two more processors cut the time in half?Reply -
back_by_demand Are they hoping that when they get to something daft like 100 trillion digits is stops recurring and becomes a fixed number?Reply -
andy_newton What a useless use of such a computing power. Might as well make a heater out of those Xeon machines for my dog.Reply -
alyoshka Another calculation...... that's not to anyone's use..... plus the amount of electricity they wasted calculating that crap, they could have easily folded those 2 processors and got a good number on the folding list atleast helping someone calculate something more meaningful and helpful.Reply -
"waa its not helpful, you should use it for curing blahblah disease"Reply
stfu. without scientific and mathematical advances, you wouldn't be able to 'fold' at all. this is a mathematical advancement, which will lead to more accurate scientific measurements. if we followed your logic, we'd still be creating scientific ways to determine if someone is a witch. -
