Pie Day Experiment

Topic

New Reply

Hey Y’all,

Yesterday being Pie Day (3/14) I ran across a post about calculating Pi and thought I’d give some open source software a whirl and see how things played out over my two desktop Dell systems a couple of years apart in technology. I used the y-cruncher software which gave a nice output from which I extracted the most interesting information, at least to me. Note that I set the software to calculate Pi to 1,000,000,000 decimal places! Also, I set it to do Multi-core calculations since both machines were 4 core / 8 thread machines.

The Contenders:

My current driver a Dell XPS8920 with i7-7700 purchased 8/15/2017:

My previous driver a Dell XPS 8700 with i7-4770 purchased 7/15/2013:

Here’s the results:
Calculate-Pi-Test

I was rather surprised that the newer machine didn’t outperform the older by a larger margin!

May the Forces of good computing be with you!

Were the several cores engaged during the calculation, or did everything run on a single one?

So you computed only 1000 digits of pi. If you would have gone up 10,000,000, you might just have been able to get to God’s message and find out what it says.

(Either you know what I mean, or you have not done much reading of Carl Sagan’s writings.)

Oscar, used all cores and calculated to 1,000,000,000 (error in OP, fixed, see PDF!) places…no message!

“No message”, eh?  Well, knowing how God is like, I’m sure that means something.

Well that’s a pretty Euro centric view of things…LOL!

But even in Europe, e^iπ + 1= 0.
I hope.

On a side note, my bank PIN is the last four digits of pi.

WSgsterry: That is just sad. I imagine it is the result of some unfortunate accident. If being unable to fix it, probably because you did not have a chance to learn the accidental PIN, you really should have a talk with someone at the bank to get this corrected. And to ever be able to get some money at the ATM before some people waiting in a long line behind you while you calculate Pi to find your PIN, start to get really aggressive.

They will be waiting a VERY VERY long time. Maybe you should use the first 4.

Just because you don't know where you are going doesn't mean any road will get you there.

Wavy: “Maybe you should use the first 4.”

Or, better and safer, choose any other known group of four figures. Plenty to choose from, as Pi has been calculated already to several trillion digits (electronic computers, where would we be without them?)

https://www.guinnessworldrecords.com/news/2022/3/new-value-of-pi-calculated-by-swiss-university-at-over-62-billion-digits-694748

(Notice that in some countries (e.g., Switzerland) the ‘trillion‘ is called a ‘billion‘; and a thousand trillions, a “trillion.”).

Besides, according to Carl Sagan’s science fiction novel “Contact” (later made into a movie), the farthest-to-the-right decimal portion of this transcendental number is a ciphered message from God. And one wouldn’t want to mess around with that, would one now?

(Retired Geek says he did not find this divine message, but he did not go anywhere far enough looking for it, in my opinion,)
