After 23 days,1000 computers and 500 years of combined computing, Nicholas Sze of Yahoo still walked away with zero. That should teach him not to mess with Pi. :p

The heart of the calculation made use of an approach called MapReduce originally developed by Google that divides up big problems into smaller sub-problems, combining the answers to solve otherwise intractable mathematical challenges.

I wonder if this method can be used to crack passwords with brute force?
 
Nicholas Sze, of technology firm Yahoo, determined that the digit - when expressed in binary - is 0.

Really? Isn't that like a 50/50 chance? I thought binary was only 1 or 0...
 
Lol they should make a shirt that says "don't mess with pi(the symbol)". I would gladly buy one for $10.

To find the last digit of Pi (without rounding) is of great interest to science.

I think that has as much importance as finding out the last digit in 1 divided by 3. .333333333333333333333333.............................

Yes because Pi is not one of the most important figure used in scientific and engineering calculations :rolleyes:.

what is the point in finding the 2 quadrillionth digit of pi? To say you can?

Read the article. He explains the benefits:

He said the current, single-digit record is "more a demonstration of the Hadoop parallelisation framework... it can demonstrate the power of new algorithms which could be useful in other fields".

The record-breaking MapReduce approach, he said, is useful in physics, cryptography and data mining.

It's a tech demo, in essence. Finding the digit doesn't matter, but the solution can be used for other problems that do matter.
 
Did they show their working? No. Oh they fail the test. Anyway theres a 1 in 10 chance that the next number is 2.

And pi does matter, its the only way to do shit with circles. And stuff...

You have a calculator that can put that many digits on? :eek:

So....we can make a circle more round?
 
Wouldn't 23 days of 1,000 computers be equivalent to 23,000 days = 62.97 years? I don't see how they rounded that up to 500 years, unless Yahoo thinks 1 of their computers is equivalent to 8 "normal" computers. :confused:

So what was the digit in decimal form? The article said it's binary 0, but there are only 2 choices there.

Can you imagine a circle so round that even God is in awe. :cool:

Hey thats heaven. in old stuff heaven (the mystical plane whatever) was represented by a circle and the earlh (physical stuff) was represented by a square (four corners of the earth?) anyway thats apparently why columns are important in churches, because they are the joining of a square and a circle... Or something.

Past 8 to 10 digits, it really isn't. Certainly not from an engineering point of view.

Exactly what I thought too. :D It's off by a factor of 8 so all 1000 computers could have been 8 core and/or 8 threads and it works out.

Wouldn't the last digit be .... 3?

Seriously, Phi is an irrational number, 1/3 is a rational number, too completely different beast.

Anyway, good luck, try again

Phi != Pi, but yes, both are irrational.

Its like the avatar "it took us 90 hours to render each frame" or something stupid. Which for a 2 hour film, with 3d at 50fps (because of blu ray) is 120(minutes)x60(seconds)x2(3d)x50 (fps) 720000 frames. At 90hours per frame thats 64.8 million hours or 7412 years. But it took them 12 years os something to make, so they must have used 617 servers. Peoples makes up shit to sound impressive. It called exagerating, its fun!

My 5gh/z i7 OC runs at 18c in my room that doubles as a sauna, on the stock HSF. I used undervolting and no HT...
 
These people are heroes. the number of lives this will save is unfathomable.

Sounds like "something" a pedophile priest (well, any ol' priest, who am I kidding?) would say to justify why they keep sticking their square pegs into little boys' round holes...

But if there's any religious motivation behind this research (there's not), well, may God help us all...
 
This requires a little hazing... oh Ogre!
