[QUOTE=PvtCupcakes;23789226][editline]06:51PM[/editline] That server isn't even that good. Only 2 CPUs? Tons of webservers have at least 4 at the minimum. [editline]06:51PM[/editline] 96gb of RAM is nothing as well.[/QUOTE] trololololololol

They forgot to throw in a few Teslas
Do want that PC
[QUOTE=ButtsexV2;23792362]before you idiots go spouting "troll", there is some validity to this post. those specs are pretty average in the high-end workstation area.[/QUOTE] No, it's not valid and it's a stupid point to make those specs look like complete utter shit when they aren't, and they aren't [i]average[/i] parts either. Compared to what, may I ask? The high end servers that Valve/Google/Blizzard uses? Fine, call it whatever the fuck you guys want to call it, I don't care. The rest of us probably could care less about both of you shitting on 32 Terabytes of hard drive space. The fact is those components cost a fuckload of money, 2 Intel Xeon X5680's are 1800$ each, and the rest of the system probably adds up to 6000$ once all the transactions are done. Seems cheap for the major companies but for the average consumer I would rather buy 3 systems with 2 GTX480's and a nice i7 920 @ 4.0 GHZ with custom water loop setups rather than achieve a world record that would be beaten within 6 months. Also, Linux is not guaranteed to run faster on this program, and probably won't run faster anyways. WinAPI doesn't have enormous amounts of overhead like OpenMP does, so it's more than likely the benefits of using Linux would be outweighed. [editline]01:55AM[/editline] Also, seriously? "Tons of webservers" using 4 Physical CPUs? lol
The specs :psyduck:
i want one of those CPU coolers and here's some person, wasting 96 GB of DDR3 RAM while i've been trying to scrape up $70 for 4 gigs to finish my PC :frogdowns:
Add 2xHD5970 and call it HD11940 and sell it for 5 million dollars on ebay [editline]03:28PM[/editline] Oh, and lights
[QUOTE=ButtsexV2;23788801]you can't deny that Linux is more efficient than NT for number-crunching. really this should have been using an application-specific operating system. BareMetal OS probably would have been better suited for this.[/QUOTE] I don't deny it, it may be true, it may not be. I am not familiar with the particular operating system you call "linux". But every fucking thread about windows he comes in the thread and obviously trolls about how linux is so much better and it fucking pisses me off that he can get away with it without a permaban.
[QUOTE=Dark-Energy;23796892]WinAPI doesn't have enormous amounts of overhead like OpenMP does, so it's more than likely the benefits of using Linux would be outweighed.[/QUOTE] Actually, on Linux you would probably fork() rather than create an expensive thread.
That's outrageous.
[QUOTE=FLAPJACKDANNY;23786163]Wheres the video card?[/QUOTE] You don't need a graphics card to calculate pi, they're not playing MW2 ffs
[QUOTE=Dark-Energy;23796892]Compared to what, may I ask?[/QUOTE] I already said, the high-end workstation market. It looks insane because we simply don't need that kind of power. this system isn't exactly unique.
Holy shit!
[QUOTE=PvtCupcakes;23789226][editline]06:51PM[/editline] That server isn't even that good. Only 2 CPUs? Tons of webservers have at least 4 at the minimum. [editline]06:51PM[/editline] 96gb of RAM is nothing as well.[/QUOTE] Each Xeon has 6 cores, that's 12 cores. Logical cores =/= Physical cores. Most webservers hosters consider a logical core as a physical core when they sell it. And 96 gb of RAM isn't nothing, yes server hosters have them, but they aren't dedicated to one thread. Now kindly leave this thread, Linux isn't better than Windows, we don't care about which OS would have done that faster, fuck you, and let's all live with rainbows and butterflies, dancing with Pi numbers.
But the real question is...who cares?
[QUOTE=windwakr;23786666]Because there's no point. The most a normal person needs is the first few digits. And you only need around 40 for anything super precise: [/QUOTE] [quote]For example, the decimal representation of π truncated to 11 decimal places is good enough to estimate the circumference of any circle that fits inside the Earth with an error of less than one millimetre, and the decimal representation of π truncated to 39 decimal places is sufficient to estimate the circumference of any circle that fits in the observable universe with precision comparable to the radius of a hydrogen atom.[/quote] That's actually really fascinating, thanks.
[QUOTE=InsanePyro;23815487]But the real question is...who cares?[/QUOTE] Nobody except the people this guy beat.
Kind of an overkill but if you got the money then why not? Ha
You need that much RAM just to perform a calculation? What's the point of trying to find this many numbers of Pi anyway?
[QUOTE=Sonicfan574;23818485]You need that much RAM just to perform a calculation? What's the point of trying to find this many numbers of Pi anyway?[/QUOTE] Bragging rights That is all
Not bragging rights. Large computations require tremendous amounts of swap space. It's essential to have as much ram physically possible, as the amount of memory speeds up computations exponentially, otherwise it uses the hard drives. The other 32TB of swap space which will be used most of the time as larger computations require a larger minimum swap space capacity, and is bottlenecking the computation, but it's impossible to have 32TB of ram in a system unless you can compute this over a network of systems, which I don't believe is possible on this program yet. [editline]12:46AM[/editline] If you mean bragging rights as in setting the world record, well maybe, but someone has to do it.

GOOD SWEET LORD @ THAT COMPUTER /caps
3.14159265 is as far as I ever go, but wow, 5 trillion ~how much would this PC cost to make?
:psyduck:
[QUOTE=ForTehWolf...2!;23829312]3.14159265 is as far as I ever go, but wow, 5 trillion ~how much would this PC cost to make?[/QUOTE] A lot. No, but seriously, you could use the internet and work it out by yourself. I think I might find out, myself.
yes do your math homework mister! Get us that estimated cost =D
[QUOTE=ForTehWolf...2!;23829312]3.14159265 is as far as I ever go, but wow, 5 trillion ~how much would this PC cost to make?[/QUOTE] likely somewhere around 8000 USD, depending on what specific parts he got and where he got them.
