NVIDIA: Adam and Jamie explain parallel processing on GPU's

[zlazher]

this is so stupid, why compare two different products who are for different purposes with uber-expensive machines?

[DaBurntToaster]

@zlazher because some people are too stupid to get it by words, and this makes lots of money

[MrToiletface]

adam and jamie explain paralell penises by space docking cuz theyre fuckin faggits, they always fuck off camera jamie receives

[GoFailCom]

than why cant GPU take over CPU?

[threeclock]

@GoFailCom Two different jobs my friend.

[adrenalinerush45]

lol at adam throwing covers while jamie's talking

[SonarWavePulse]

And the slow motion shows the diffirent packages of balls arriving with delay, microshutter.

[beatle11]

Ladies and gentlemen; science class is now over!

[k0k090]

If i see those two in Copenhagen, i am buying them a beer

[Simpson654]

In applications (like games, or modelling software, or any 3D application, even your standard desktop these days) the GPU is tasked with creating the visual representation of what the CPU is doing. The CPU is good at doing tasks like calculations and following the program, while the GPU is doing the repitive tasks like painting a similar picture 60 times a second. CPUs nowadays are going for parallel processing, with multiple cores (CPUs within CPUs). Eventually they might meet.

[thedaveboyle]

a glorified ink-jet printer

[tehcubanwhite]

Anybody else notice "written" was spelled wrong?

[wurstgesicht147]

awesome ^^ i like them and the way they describetd it ^^

[rockerojuan]

Yes a GPU can be really powerful, but a GPU can't do everything by itself, the CPU helps it render more than you think.

[wardjee]

AWESOME! :O :D

[Flybyhacker]

where to get original video???

if you know ....TELL ME

[nick113z]

is that?!? an SP-1? haha they must be the last people to buy from smart parts before the went belly up

[mPowerGmbh]

@nick113z SP hasn't gone belly up actually... I personally bought like 20 markers from them personally within the last 4 months. (10 ions / 7 ion XE / 3 Shocker NXT ) since i like to go paintballing with friends and its cheaper to just buy them rather than pay bullshit 80$ rental for wifebeater spyder's with CO2 and stock barrels.

[nick113z]

@mPowerGmbh ya they are still trying to frigure things out with the banks, but they arent making new markers right now, if anything they are just selling off what they have left in storage

[kkjgg112391]

Okay so this is what caused nvidia to lose funds for the fermi project? LOL

[rockerojuan]

@kkjgg112391 LOL

[kkjgg112391]

@rockerojuan seriously, haha!

[csrtitus]

cool stuff.

[paasukusai]

最高ｗ

[bigphantom75]

epic....

[faloc]

8bit mona lisa! :)

[TheHomelessCripple]

What horrible resolution on the Mona Lissa

[Jschroyer88]

The GPU made it all happen in under 1 second genius.

The CPU shot the paintballs out individually.

The GPU calculated the air pressure, time, etc. so the paintballs would fire simultaneously and faster than any gun could fire them, without the whole thing exploding.

[netherfoam]

Holy mother of failbots...

The "Uber GPU" Has to fire all the "paintball guns" at once! Thatd be amazing.

Only one thing... if you had 1100 paintball guns lined up, and had each tied to a piece of sting, yanked the string, you could paint the mona lisa too!

Gpu has to do zilch but pull the string -.-

Thats NOT parralel tasking or multitasking or w/e they want to call it. Thats something well frankly I think the closest thing youd need to a GPU is a pressure gauge, and air compressor/pump.

[TheHomelessCripple]

it was a metaphor. The parallel tasking was the multiple guns shooting at once, while the single tasking CPU could only shoot 1 ball in succession.

[JoshyNapalm]

@netherfoam wow, you are a moron.

[marsniper27]

NVIDIA RULES and so does the myth busters put them together and you get something epic! GPUs can do more faster the a CPU keep CPUs for math leave graphics to NVIDIA!!

[Gowalingla]

lol idk wats happening here but why are they two were actually doing , i mean explaining??and why were them?not pc engineer or bla bla bla XD

[beatle11]

LMAO...Just perfect.

[R1zZzo]

8:49 = fuckin epic :)

[kaliappan1vinod]

superb...

amazing work by those ppl.....

i got something about GPU and CPU...

[sIrdakz]

... that was damn awesome...

that was indeed the concept of GPU's...

[rizkyp]

are they replicating the result or the size of the GPU LOL

[vanert1]

That's legit.

[Jaredo66]

That's fucking awesome! :P

[LehdaRi]

4:06

Adam: "We're gonna need - we realized - a bigger bot."

Ppl: "Yeaaaahh"

Jamie: "Yeah we need a bigger bot. Then I started to think we need a REALLY BIG bot."

Ppl: "YYYYEEAAAAAAHHHHHHUUUUUYYYY!!­!!11oneoneeleven"

:D

[DemonicDerek78]

Serial Processing (CPU): 2:52

Parallel Processing (GPU): 7:57

[stephenm2]

Liked it and there is a big difference in the CPU and GPU

the CPU does all the operations and basic imaging, the GPU then takes that image and renders it making the image manytimes better, some grapgic cards completly skip the CPU anf do all the imaging itself allowing your computer to run at a higher level

[ofird1]

COOL! looks like the main scence actually starts at 7:54

[colmmernagh]

Glayvin glowbin !!

[penguin1853]

these science stuff is cool

[ggaeta91]

You my friend, just made my night, in the least expected way, I couldn't even describe to you.

[krauser979]

lol copy and paste

[techforumz]

It's an analogy. A 6502 could do either/both job

[keitaru]

It is just an example of CPU: Processing unit and GPU: Rendering Unit.

Please don't use the abreviation of CPU and GPU to explain what the diffs cuz they are just they for the english.

[oc3ans12]

the slow motion looks awesome xP

[Mosfet510]

The Mythbusters are great! BUT....I was waiting for them to blow the canvas up...oh well

[m4r3z]

Gpu folding ftw ! ;)

[GreatGreen]

Just look at all you nerds arguing!

Hilarious.

[Enginekrazy]

Looks like he forgot to install the drivers for his GPU. xD

Pretty cool stuff, though.

[Leadwerks]

The problem with GPU processing is that very few problems can be parallelized the way it needs, making it useless for almost everything.

[frother]

They invited all of the Intel graphics people to this conference to sabotage their employees

This is so outrageously inaccurate

[foxracingpeople]

did the mythbusters acc build that thing? wow

[DEMONOFMORROWIND]

remember that before mythbusting they built robots

[danny3man]

as anyeos said GPU is for graphics and derivated work.. do you have any idea how long does it takes to render a 3d scene .....i tell you a lot ...from hours to days

[scratchyrice]

I am a game dev mate. Due to the stream processors now found on modern gpu's, They can be used for a LOT more than just graphics work. For example, The PhysX api can run on a modern 8 series gpu or above, Because of these stream processors and their programability. Methods that were once limited to applications such as maya and 3dsmax, Can now be done at a good 60FPS using modern GPU's. Thats why crysis looks so good. Also offline rendering is done on the cpu, not the gpu, So processor is key.

[JuggaloMike20]

LOL YALL ARE WAY TOO SMART FOR UR OWN GOOD : P i kinda follow u guys on what ur saying tho

[3Dinvent]

You have no idea what you're talking about do you...3D scenes can be rendered in milliseconds, take 3D video games for example.

[danny3man]

if it`s a very small scene or if you have a big render farm .... and about video games ..i think you are trying to say that in 3d video games everytime you enter that game the scene it`s rendered...if it`s that so you are wrong ... the scene it`s just loaded from pc , that`s why some games like gta 4 or sacred 2 are so big ....

[scratchyrice]

Thats right, Everyone thumb me down because i know what im talking about, And you cant accept that nvidia cheated in this case, I mean im a fan of nvidia! But still cheatings cheating. A CPU can handle 200 pixels (about the equivilent of that paintball gun) in REALTIME with ease. All that does is basicaly fire one frame, So its not even realtime, Its offline rendering. So how in the ASSSSSSSSSSS would people need more than a cpu for this?

Some people are just fools i guess.

[jeremyshaw1]

How come CPUs still cannot render frames with ease? There is more then just 200pixels at a time.

GPU can handle mutliple framebuffers (offline rendering), and can automatically add occulsion, culling, aa, af, textures.

That cannot be easily handled by a CPU, on a limited bus, with limited parrall processing capability. Multiplied by millions of times over, the CPU just loses out. It cannot outdo the amout of raw processing the GPU was designed for.

[scratchyrice]

I never said cpu's could render 3d frames with ease. All i was saying is that what nvidia showed here could easily have been done on the cpu, even in realtime. 1100 pixels is not a lot, especialy when ur not applying fragment shaders to each and every one, Comparing to say a resolution of 1280 x 1024, totaling 1310720 pixels, in SCREEN SPACE, then you have to account for all the fragment and vertex calculations being done in object space, Theres a big big diffrence.

[Dallasdeckard]

How ridiculous! Who CARES if a CPU could "handle 200 pixels with ease"? Huh? What they are trying to show is the advanced capabilities of a GPU! They aren't trying to say, "Oh, a CPU couldn't do this"! NO ONE is saying a CPU or a GPU was responsible for this demonstration. It is simply a METAPHOR concerning the difference between a CPU and a GPU.

It's meant to be FUN, not precisely accurate. Geez, get a life.

[scratchyrice]

Woah calm down. The title is Adam and Jamie EXPLAIN ...., This explains nothing especially since its not even accurate! If they wanted to explain the power of parralel processing gpu's, They could at least give a flocking, physics, fft demonstration, something that actually uses the technology.

[Dallasdeckard]

They did a good job of providing some fun and metaphor concerning the difference between a CPU and a GPU. No one, except a dorky super-nerd would need them to do something that "actually uses the technology". I guess Jesus shouldn't have used parables, because they were about different people, and not the people He was talking to. Duh.

[scratchyrice]

1. Fuck off with the "dork" shit. Skills pay the bills ;)

2. Whats the point in the fucking technology, Unless its actually used.

[Stuna2150]

your missing the point completly *scratch* ..

and since you dont get it i think you should just give it a rest ..

[1981z28camaro]

well you can't give a flocking fft demonstration to most ppl, considering 99.9% of the human species doesn't know what the fuck that is. This is the best way to show the average person what it means, basically they are showing that instead of doing it all with just one line of paint, (whatever the fuck you wanna call it) painting the whole thing,and taking forever, it's showing it doing the whole thing in an instant.

[scratchyrice]

Maybe fft would be another bad demonstration, But So is what they are doing here. I mean when u open a photograph in photoshop etc, Its not like you see the image scaling across the screen pixel by pixel. IF they really wanted to show parralel processing, They should have used the same idea, BUT rendering something on the canvas in realtime. Now that would be impressive!

[1981z28camaro]

yeah, I think they just wanted to be interesting about doing it, and this is what they thought of. even if it's not the best way to show it. I guess it was the easiest way to show average people.

[scratchyrice]

Indeed

[scratchyrice]

Whats so special about this?

[anyeos]

Yes CPU is single thread but have more options than a GPU. A GPU only process graphics and is limited for that and all graphics derived works. But CPU can do a much more variety of works. In the representation you can see it can walk and aim in range, the other one is more heavy and only can aim parallel. In a real CPU and GPU the like happens.

[scratchyrice]

The gpu can perform any highly parrallel mathematical computation, Not just graphics specific. So physics, AI flocking, Anything that just requires fast calculations rather than any conditional statements, Which is where the cpu comes in.

[anyeos]

Aaah ok it is like some "co-processor floating point unit"? :P

Not bad but I have an old GPU that is not util for me.

[Gaeuvyen]

I like when he mentions robots you hear the crowd cheer but one over the rest you can clearly hear him say, "YEA! ROBOTS!"

[dapa4]

the mona lisa pic. looks kinda like the old mario graphics

[bestSVMS]

lol

the guy hollored

I WANT FREE STUFF

[nimijokaolivapaa]

2:31

[0501701]

what did that dude say?

[NICKSTER117]

you break it, you buy it

[cneyr]

It's really rather simple;

Leonardo 1.0 is an example of a regular CPU, in this case "drawing" using a single "thread", or one paintball at a time. it has to process each location individually, and has to re-aim after each one,

Leonardo 2.0 is an example of Parallel Processing, using a "multi-threading (or parallel) processor" (1100 barrels) and is able to process each paintball simultaneously.

[RiseofFooDos]

Ok I see, do you mean gpu's though?

[cneyr]

I meant that leonardo 1.0 is a CPU, 2.0 is a multi-threaded Parallel GPU.

[RadioChris93]

@cneyr you basically just said what they said....

[xLittleVinnie]

@cneyr

thanks !

[ZATMNU]

I would've laughed so hard if there was a barrell break or chop xD

[Thesixthgoon]

They are insane1 XD

[TheBeastUponTheLolz]

I wonder how many frames per second you can get on that? :P

[iwan0t0smith]

if every barrel had a machine gun mechanism you could get at least ten. You would also need to work ou t a way of replacing the backdrop

[CradLeRcker]

i think there were a few dead pixels... lolol

[evilcult23]

lots of drooling fanboys in that room

[woodsballer1994]

thts the paintball gun i have....on the leonardo bot, but they kinda took alot off of it

[henriko95]

Sorry about the mix up in my comments......

[m1o2]

wow it's awesome!!!!

[4DUMBASSES]

nvidia ftw!!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!

[S1meN]

This is an awesome video ^^

Only thing that bugs me is my curiousity...

Why do they launch the lower half of the paintballs first?

At first i thought it had to do with the contrast ect ect... But there are black spots on other places aswell.

So please. Enlighten me :)

[rcreaney]

They keep complaining on the show that they cant get things to fire symultaneously

[henriko95]

The video is slowed down so much that the eye would normally see it being fired simultaneously. If two people decided to fire there paintball guns at the same time, they would have the ability to fire really close together, but still it would not be at the exact same time. The rest of the explanation is under here.

[henriko95]

There will always be a slight difference in the shots. BUT the human eye cannot see it normaly. It is also possible that the gas had less travel distance to the bottom tubes, and therefore shot them first.

I would like to apologize for my crappy english, but i'm from norway. I hope this has Enlightened you, S1meN.

[bobwatters]

they said that all the tubes were the same length so it was probaly the way they were bent with less resistance i would bet

[sanderwright74]

awesome!

[SuperXgerM]

DOOD slo mo is soooooo SICKKKK

[tack129]

That was awesome.

[YamiChan31]

slow motion=just wow

[DarkDesire1974]

I call this myth ... BUSTED :-)

[DROW42]

IT WAS CONFIRMED!!!!!!!!!

[pooladden]

lol 2:30

[scorpserpent]

gosh..now i feel inferior with my Geforce 9400gt..

argh

[irishshmoe]

wow.....

[Theowest]

my nvidia just broke.... Now I can't play on my computer...

[darthcertde]

check out that slow motion at the end

[pokerface3699]

that would ruin the whole point in parallel processing

[BryceHillam]

8:49

[bzar18]

3:57 / 9:22

[XFolf]

Does this mean I can take my 260GTX+ to the local field with me and not suck anymore?

[Kevrill]

That's pretty cool to watch at the end where it plays in slow motion

[pinhedi]

GUYS. Don't be a dick to darkcurrent. He WILL stalk you, trust me. Adam and Jamie are awesome.

[darkcurrent]

Adam and Jamie are fucking retards. Adam never went to university. Jamie got some shit BA in language.

Shut the fuck up pinhead.

[pinhedi]

you know pinhead isn't insulting in anyway. And it doesn't matter if either adam or jamie went to a university. They were probaly trained before the show. dumbass

[darkcurrent]

Yea, you get a real great education by being "trained before he show".

What a fucking moron.

If it's not insulting, then shut the fuck up pinhead.

[pinhedi]

I never said they would get an education. And plus some of the smartest minds in history didn't do very well in school. So education isn't all that important, long as your always curious and trying.And go ahead and call me what you want. WATCH ME CARE. BIG DEAL. I bet you don't want to insult me anymore. Cause it isn't any fun. ha ha. not funny.

[darkcurrent]

Only retards use that argument... but you keep telling yourself that.

I'm sure the 40 yr old with a high school education working at MacDonald told himself the same thing at your age.

Stupid shit.

PS: I never tire of humiliating faggots like you.

[pinhedi]

you know. I'm not humiliated in any way. And i was just making a statement. I was trying to argue about it. And i really didn't want to know that your 40 yrs old and working at McDonalds. And didn't i say that you have to be curious and open minded and always trying? I'm pretty sure I did. That was you flaw in that field.*sigh* NEXT!

[darkcurrent]

learn to read bitch.

[darkcurrent]

Of course you're not humiliated. To be humiliated you need to actually know that you're wrong. You're too stupid to know that.

Unfortunately, those of us that are educated will laugh at you.

My advice?

images.despair.c0m/products/de­motivators/giveup.jpg

[pinhedi]

since when did you get an education!? That is just amazing. I didn't think 2 yr olds could get educations. Technology has come a long way.

And go ahead and laugh. Watch me care. I am SOOOOOOO offended.

YAWN! NEXT!

[darkcurrent]

It doesn't matter if you're offended or not. I just want you to know that anyone who knows about computers are laughing at you.

Oh yea, I'm 2 yrs old, but I understand the reactions being written here:

youtube.c0m/watch?v=XsZ4ZPFwFN­M (or search for "chemistry is sexey II" in youtube)

Do you?

Got beaten by a two year old again?

Dumbass.

[pinhedi]

No, i have a perfectly fine computer. And your just jealous. and I just posted here nad on that vid the explaination to RAM. lets compare it to what you said. Nope, your wrong

[darkcurrent]

Wow, are you so stupid you can't see the irony?

"Th RAM is just there so running app data can be accessed immediately."

"Th HDD is fast enough, but it is more efficient if you can access it in the RAM."

Sounds to me the RAM acts as a BUFFER because the HDD is too slow... which is what I said. Boo hoo, I win. If the HDD I/O was fast as the I/O of RAM then RAM wouldn't be needed now would it?

What a dumbass.

Rendering a 3D movie? (can you seriously stop making it so easy)

[darkcurrent]

What happened to your idea that the HDD can feed the CPU fast enough with data?

HaHAHaHaHAh.

Hilarious.

[josh101josh]

lol, geeks arguing. =]

[Herkko94]

wow nice! i love mythbusters show! adam and jamie are both wery smart and funny!

[Unixsirs]

Cool Video:)

[Undergrounders69]

they used that on youtube live

[lrnman]

imagine getting hit with that mny paintballs in 80ms ouch dat gotta hurt lol

[sBRANe777]

Bravo guys...awesome

[ZEATER666]

you can tell there famous because every famous person has HATERZ

[tomazaga]

how do u know?

[samaow]

dude its a fact its called "tall poppie syndrome"

[pinhedi]

your a computer noob. I bet you don't even know what the RAM does.

[darkcurrent]

Shut the fuck up retard. You don't even know the difference between "your" and "you're" and you're lecturing me about RAM?

The function of RAM is just a buffer because your HDD is too slow for your CPU... so frequently used files are stored on RAM for faster retrieval. Same as L3 L2 and L1 cache except much bigger.

Go choke on a fatty.

[pinhedi]

o yeah, be a dick about spelling u nerd.F rom now on i'm gonna spell everythin' wrong. I find it funny that u say that SATSA is to slow even though it can pass up to 3 Gig of data at a time. Thats why its called SATA 3.0Gb\s dumbass. and there differance between your and you're is that one stands for "you are" and the other is possesive. Besides who cares?! its the interweb, nobody cares. Why would they create RAM even though the HDD can pass 3.0 Gig a second. So you can now run home to mommy.

[darkcurrent]

What a fucking noob. Do you really think your hard drives can actually read and write at 3Gb/s? Idiot.

It doesn't even matter, since the new DDR3 RAM work at 12.8GB/s with nanosecond latency compared to the millisecond latency of mechanical HDD.

Hmm, let's see 12.8GB/s RAM vs. 375MB/s HDD transfer speeds... and you ask why would they even need RAM as a buffer.

Fucking Noob.

[pinhedi]

yeah they can

Its called "SATA 3.0 GB\s" look it up. I don't care how fast your DDR3 RAM is. you said that the HDD is to slow for the CPU. and i just proved that it isn't. and go ahead and mark my comments as bad. Watch me care.

[darkcurrent]

No retard, they DON'T call it "SATA 3.0GB/s". They call it SATA 3.0Gb/s. The small case "B" stands for BIT not BYTE retard.

So yea, a transfer speed of 375MB/s HDD is too slow for the CPU... at least compared to the 12.8GB/s of RAM.

Now shut up like a good boy cause you've just embarrassed yourself.

[darkcurrent]

I forgot to mention, Adam, jamie and pinhedi noobs that should not be "explaining" anything... parallel processing or otherwise.

I suggest you to shut the fuck up like a good bitch before I really rip you a new one.

[pinhedi]

I can explain a lot of things. Docter "I Know Everyrthing". If you know so much. Why are you watching this video? Plus you can't rip me a new one. And you want me to be your bitch cause your GAY!!!!! no way!

[darkcurrent]

I didn't watch this vid. I just said jamie and adam are computer noobs that should shut the fuck up about shit they know nothing about.

PS: What I know is common knowledge, it's only that you're so fucking retarded that you actually think I'm smart.

[pinhedi]

I never said that you were smart. I actually think that your a stalker and a Fucktard. Cuase then you went to my profile and posted shit on my stuff.

[darkcurrent]

I change my mind, I don't even think you've entered highschool yet.

Sorry, but going to someone's youtube profile and then "posting shit" does not mean stalking retard.

Egotistical, stupid and ignorant... characteristic traits of immaturity and the pre-pubescent, acne faced, teenager full of angst.

Shut the fuck up faggot.

[pinhedi]

but,

Then going to ALL my vids and posting stuff there too. That is just creepy.

[vonfreud]

Pretty cool!

[Semolika]

That was awesome!

[DJhedgehammer]

good ol' mythbusters always do some ott,supergalactic shit.. these guys are definitely stoners!! XD

[ampentium2]

it says that, in the gpu each pixels u see on your screen is processed in parallel to each other, compared to cpu each pixels needed to be processed one by one... making GPU process faster than CPU...

but still, i dont think the comparison is good enough though... however, that's the simplest way to explain... or at least what i think...

[47CryXMA]

i don't get it. how does this compare to an actual gpu?

[bopskk]

lol great :))

[Choice777]

why don't you kill yourself ? and your mom for not killing you at birth ?...of course i'm joking......noone fucing cares about your complaint....go live in the fucking woods if you think you deserve better.

[YOUHAVENOFRIENDSFOOL]

Have u seen their Quadro FX 5800 card? Its a 4 gb monster!

[Thurrock2]

Yeah, its awesome.. And only costs £3,000 :D ($4,500)

[fetzerveeble]

A lotta fun. Good watch.
