New Multi-Threaded Pi Program - Faster than SuperPi and PiFast

haha. yep!

Disk is the clear bottleneck... So I made it so that you can fix that by just throwing more drives at it.


@skycrane

You've got very some serious competition to 1 trillion digits.
Want me to PM you the specifics?

Actually, if you're willing to run that awesome machine of yours for more than a week like that, you're actually in good shape of breaking some of the world records for the other constants.
(Namely the records that I set between March - May last year.)

e, Log(2), and Zeta(3) are your best bets.

e:
I recently set this to 500 billion digits on my Core i7 machine with 12 GB ram + 4 x 2 TB. It took 12.8 days to compute and verify.

Log(2):
This was done to 31 billion digits last year on my 64GB workstation. But it only took 40 hours to compute and verify. So 50 billion digits could possibly go sub-one week if you have enough drives running in parallel.
Same applies to Log(10), but no one gives a crap about Log(10). So lol.

Zeta(3) - Apery's Constant:
This was also done to 31 billion digits last year on my 64GB workstation. It took 4 days on my workstation to compute and verify. So it's slower. But there's a Wikipedia article on it with a list of records.


I didn't mention Square Root of 2 and Golden Ratio because there's someone already working on that.
(They're both already computed to much more than the current official records, but are both pending verification.)

Catalan's Constant and the Euler-Mascheroni Constant don't support Advanced Swap Mode yet, so you'll need more than 64GB of ram to beat those. (Not to mention they are both FREAKING slow...)

yea poke, can you send me the pms id like to see what this can do before MM destroyes us all with his 12core machine hes got... lol

well this sucks, looks like the disks i got wont work, they are to slow to move that amount of data Particle was talking about. maybe ill see if i can use my brothers NAS hes got. do you think on a gigabit line, if i have enough disks for it, that it would be fast enough to handle the bandwidth?
or would it be better to run 7 or 8 drives off the mobo?


poke, here are the updated of my runs i did. they are a bit faster. i had some programs running in the background , and i was doing this over my NetOp and it was slowing down all my runs
