yeah, this is one curiosity teaser
I tried advanced swap mode, but when I set it to use G:\ the program went into an infinite loop (still in the menu, hadn't even started yet).
Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Rule 1A:
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
Rule 2:
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
Rule 2A:
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
Rule 3:
When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
Random Tip o' the Whatever
You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.
Where in the menu?
It asks you for the # of drives first. Then it asks for the paths.
I should probably write my own prompting function instead of using cin >> c;
Since cin >> x; does that infinite loop when it gets a letter instead of an integer.

can you put my runs in?
Its not overkill if it works.
ive got a few more
im working on the 10 and 25 billion right now, hopefully it works

Quick question: Do you actually have enough ram for the 10b and 25b runs? Or are you using the swap modes?

3 of them...
If you have any extra hard drives lying around, they'll really help out the larger runs using Advanced Swap.
Since you have sooo much computation power, it'll obviously be heavily bottlenecked by disk bandwidth.
Someday... I need to optimize the program better for NUMA machines like your quad-sockets... Only then will it be able to bring out their true potential...
Main Machine:
AMD FX8350 @ stock --- 16 GB DDR3 @ 1333 MHz --- Asus M5A99FX Pro R2.0 --- 2.0 TB Seagate
Miscellaneous Workstations for Code-Testing:
Intel Core i7 4770K @ 4.0 GHz --- 32 GB DDR3 @ 1866 MHz --- Asus Z87-Plus --- 1.5 TB (boot) --- 4 x 1 TB + 4 x 2 TB (swap)
id be more than wiling to run the optimized program anytime you get it ready and report the results on it. i have a perfect way to test the difference between the 2. all 3 rigs have the same tyan s4985 mobo, same memory, same opti 8356's with the same batch number and same hdd.
for the hdd, are you saying that the best bet would be to run 15gb of mem, and the hdd in a raid0 array??? to get the bandwith that i need?
would 2 75 gig raptors work better than 4 regular 7200 rpm hdds?
Its not overkill if it works.
It's not a simple fix. Virtually the entire multi-threading structure of the program needs to be redesigned from scratch and re-written to do that.
That's not something I have on my plans. So it may not be for years.(assuming I'll still have interest in the program by then)
The hardware that I need to do it would be well beyond my budget.
(I'd basically have to build myself a Beowulf cluster of high-end dual or quad-socket machines fully loaded with an absolutely obscene amount of ram.)
Perhaps a single 4P Beckton or a 4P Magny Cours machine will be enough... both of which are well beyond my budget. (And I'm speaking as a college student so i have no money or income... lol)
Basically I need a machine that is VERY Non-Uniform in memory to be able to write for it...
About the hard drives:
From the results that I have gotten so far, letting the program manage your HDs separately does seem to be more efficient than RAID 0.
So RAID doesn't seem to be useful until you run out of drive letters.
With your amount of ram (> 16 GB), disk seeks won't become significant until you push over 100 billion digits. So bandwidth will be the only that really matters. (In other words: 4 x 7200RPM will beat out 2 x raptors.)

I get about 50% loading on 12 CPUs using swap mode on my 15K disks.

my results
Config:
Supermicro X8DA6
2x Xeon X5550
6x2gb ddr3 1333mhz 99928
I just approximate Pi as 3.14, and it's pretty fast
Woah... I go away for day, and there are 4 new posts... lol
Wow... you're probably the first person (besides me), who actually went out to buy hardware to run this program.sounds good
Good luck with that. Gonna be very interesting.
p.s. Lemme warn you though... 1 trillion digits is gonna take a LONG time. As in: more than 20 days...
Thanks.I get about 50% loading on 12 CPUs using swap mode on my 15K disks.
Using just one would be an absolute pain...
The swap mode wasn't an easy task. I've been working on it (on and off) since November 2008. (well before the first release of this program)
I actually had it completely designed and laid out on paper about a year ago, but I never found the time to actually finish it.
It wasn't until this winter quarter, that my class load was low enough to let me goof off a bit.
And when I actually had it partially working, testing it was a complete nightmare since swap computations take forever.
Due to the nature of the algorithms, things behave differently for small and large computations. So a "simple" test on the larger sizes would take hours. Of course, nobody gets it right on the first try...
So I spent much of January abusing my workstation with 40GB ram drives to actually test and debug this thing...
I remember sitting there in horror when a 30 hour test failed on my Core i7 rig...
Then I got the idea to ram drive it on my workstation... made it sooo much easier to fix the bug...
(This was prior to getting the 4 x 2TB. So everything was REALLY slow.)
Wow. Another i7 dualie.
Is your system reserving 1GB for video or something? Since the program is only reading 11GB.
Been getting mostly multi-socket results these few days...
22/7 is better.I just approximate Pi as 3.14, and it's pretty fast
Both 3.14 and 22/7 need 4 characters to write, but 22/7 is more accurate.
22/7 is faster too. Fewer strokes to write.

Guilty! I've got eight Fujitsu MBA3147RCs on a HighPoint RocketRAID 4320 in RAID-5. The program moves hundreds of megabytes per second while running.
It was running on the fastest part of the disk:

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...)
