bob sherbin:
Morning (for those on U.S. time). It's an early fall day here in San Jose with plenty of sunshine. I'm Bob Sherbin, vp of corporate comms at NVIDIA, and I'm really jazzed to be live blogging.
Tuesday September 21, 2010 8:54 bob sherbin

bob sherbin:
The san jose convention center is filling up fast. we have about 10 minutes to go and the seats are more than four-fifths full.
Tuesday September 21, 2010 8:55 bob sherbin
8:56
bob sherbin:
I'm sitting in the press section where there are about 100 reporters from a bunch of business publications and lots and lots of specialized trades.
Tuesday September 21, 2010 8:56 bob sherbin
8:56
bob sherbin:
we've spent a good six months working toward today and it's really nice to be about to take off.
Tuesday September 21, 2010 8:56 bob sherbin
8:57
bob sherbin:
speaking of taking off, they're beginning to show some 3D demos to warm up the crowd.
Tuesday September 21, 2010 8:57 bob sherbin
8:57
bob sherbin:
there are some fairly high end 3D glasses attendees have been issued. they don't fold but they offer terrifying fidelity.
Tuesday September 21, 2010 8:57 bob sherbin
8:58
bob sherbin:
It looks like we're in a space ship passing through a very high tech honey comb.
Tuesday September 21, 2010 8:58 bob sherbin
8:58
bob sherbin:
there's some techno music going, no narration but the audience is pretty rapt. even the reporters have stopped typing.
Tuesday September 21, 2010 8:58 bob sherbin
8:59
bob sherbin:
the big voice is coming on giving the usual warnings.
Tuesday September 21, 2010 8:59 bob sherbin
8:59
bob sherbin:
everyone's been told to put their 3D glasses on for the intro video. they're showing 3D sonograms
Tuesday September 21, 2010 8:59 bob sherbin
9:00
bob sherbin:
a list is releling out around the theme of Right Now. Right now GPUs are being used to prevfent cancer death from radiation, nOAA is generating weather modesl 35x faster than before. the planet's second fastest supercomputer uses GPUS
Tuesday September 21, 2010 9:00 bob sherbin
9:01
bob sherbin:
Right now...researchers are using GPUs to find plaque in arteries, eradicating malarai-carrying mosquitos, to design, buildings, shampoo, pizza curst, antibiotics
Tuesday September 21, 2010 9:01 bob sherbin
9:02
bob sherbin:
video's spooling down. and Jen-Hsun Huang is coming on stage
Tuesday September 21, 2010 9:02 bob sherbin
9:03
bob sherbin:
jen-hsun, jhh hereafter, says gtc is about the amazing discoveries based on gpus and that there's an amazing conference ahead
Tuesday September 21, 2010 9:03 bob sherbin
9:03
bob sherbin:
four things, jhh says: nvidia's focus, cuda's development, and then some amazing announcements, and then a peek into the future. plus therell be some great demos, he says
Tuesday September 21, 2010 9:03 bob sherbin
9:03
bob sherbin:
NVIDIA's focused on three areas: visual computing, parallel computing and mobile computing.
Tuesday September 21, 2010 9:03 bob sherbin
9:04
bob sherbin:
He talks about each of the company's main brands: quadro for workstations; tesla for supercomputing; and gforce and tegra for consumers
Tuesday September 21, 2010 9:04 bob sherbin
9:04
bob sherbin:
Tegra, jhh says, is based on ARM because it's the instruction set of choice and the fastest growing chip on earth
Tuesday September 21, 2010 9:04 bob sherbin
9:06
bob sherbin:
Mobile computing will be enormously disruptive. It's an area where great contributions will happen. Mobile computing isn't just about portability. it's the first computer equipped with all kinds of sensors -- cameras, other situation-aware devices. because of them, mobile computing will achieve and deliver experiences not possible before.
Tuesday September 21, 2010 9:06 bob sherbin
9:06
bob sherbin:
JHH is beaming talking about tegra. He's wearing his trademark black shirt and jeans, and some really nice loafers
Tuesday September 21, 2010 9:06 bob sherbin
9:07
bob sherbin:
Next slide up is a a view of an airforce fighter jet, flying right at the audience. He uses it to talk about the importance of tesselation. Fermi's really good at. 6x faster, in fact, than what it replaced
Tuesday September 21, 2010 9:07 bob sherbin
9:08
bob sherbin:
Turns on the air force jet is from a computer game not yet released. It's called Hof, or something along those lines. it requires the representation of 4 billion triangles
Tuesday September 21, 2010 9:08 bob sherbin
9:09
bob sherbin:
the jets are flying voer the middle east. you feel like a top gun pilot. the jets are shooting at each other in 3D.a parachute would be nice right now
Tuesday September 21, 2010 9:09 bob sherbin
9:10
bob sherbin:
the really cool thing is how realistic the ground is, you can see individual trees.
Tuesday September 21, 2010 9:10 bob sherbin
9:10
bob sherbin:
sorry, the name might have been hok 2. but i suspect i'm bobbling it a bit
Tuesday September 21, 2010 9:10 bob sherbin
9:11
bob sherbin:
Next slide up is describing the GP GPU Revolution, which incorporates a CPU plus GPU
Tuesday September 21, 2010 9:11 bob sherbin
9:13
bob sherbin:
JHH introduces CUDA, which he says involved two decisions. we recognized that we didn't want to replace the CPU but augment it with a many-core GPU. Second decision was to ride back of high volume GPU biz that was GForce.
Tuesday September 21, 2010 9:13 bob sherbin
9:14
bob sherbin:
THere's another slide introducing a new concept for NVIDIA. it's called "Computing: The Third Pillar of Science." It underpins auto design, medical imaging, weather forecasting, seimsic imaging and drug design
Tuesday September 21, 2010 9:14 bob sherbin
9:15
bob sherbin:
Researchers all over are embracing GPUs to accelerate their insight to discovery. CUDA makes that more accessible. And more affordable.
Tuesday September 21, 2010 9:15 bob sherbin
9:16
bob sherbin:
I should have desscribed the stage. It's black, of course, with a bright green logo on the upper right, and a sign on the left that's green with white lettering stating, "GPU Technoloyg Conference." there are also some really cool green blow-up shots of GPU circuitry
Tuesday September 21, 2010 9:16 bob sherbin
9:18
bob sherbin:
JHH is talking about eh important of a new approach based on parallelism, drawing on work from the great Berkeley engineering department.
Tuesday September 21, 2010 9:18 bob sherbin
9:19
bob sherbin:
CUDA is that approach and it's fast adoption is evidence of that. He's going to show some demos of CUDA in action.
Tuesday September 21, 2010 9:19 bob sherbin
9:19
bob sherbin:
JHH introduces Tony Tomasi, svpr of content and technology. tony has three things to show, he says
Tuesday September 21, 2010 9:19 bob sherbin
9:20
bob sherbin:
first up is a tesselation demo in 3D. it shows a post-apocolyptic city. 1.3 billion polygons a frame are being rendered. there are over a thousand light sources. this is done through procedural tesselation.
Tuesday September 21, 2010 9:20 bob sherbin
9:21
bob sherbin:
whoah, there are some terrifying bird statues on the top of each building. they're turning tesellation on and off. when on, there 500x the fidelity. the geometry, tony says, is an order of magnitude more complex than a current computer game.
Tuesday September 21, 2010 9:21 bob sherbin
9:22
bob sherbin:
this isn't a city you'd want to live in. it's metallic, with swirling clouds.
Tuesday September 21, 2010 9:22 bob sherbin
9:23
bob sherbin:
the next demo is volumetric simulation in ufll 3d. there are two crash dummies. one's blowing nvidia-green smoke at the other who's fighting it off with a fan and imparting velocity as he does. the smoke is swirling in a way an artist couldn't capture it. this takes 20 trillion ops per second, tony said. that's 1 billion theads per second.
Tuesday September 21, 2010 9:23 bob sherbin
9:26
bob sherbin:
the third example of simulation in graphics is fluid dynamis. there's decaying old lighthouse on a stormy night, with a crashing sea and debris moving around. it's all being rendered in real time. the light from the lighthouse is casting light in different direction. The demo guy is moving around a boat and it's changing the course of the waves. It's fully volumetric. turns out this can be done on a single gpu
Tuesday September 21, 2010 9:26 bob sherbin
9:26
bob sherbin:
this latest is 5000x faster than with cpus. very realistic. enough so that you'd want to put a wool blanket around your knees.
Tuesday September 21, 2010 9:26 bob sherbin
9:27
bob sherbin:
that's it for tony, who heads off stage and back into the crowd.
Tuesday September 21, 2010 9:27 bob sherbin
9:29
bob sherbin:
Next up, JHH says, is three demos of how CUDA's being used. Momentum's building, he said, CUDA SDK cummulative downloads has doubled in a year to 670K; the number of OEMs offering TeslPro-Acessors has increased in a year from one to nine. and the number of GTC papers submitted has grown fivefold to more than 330
Tuesday September 21, 2010 9:29 bob sherbin
9:30
bob sherbin:
it's pretty rare to sit in a presentation where there's no chitchat from the audience, no sarcastic comments. everyone's listening to jensen reeling off factoids, factlettes and factettes about cuda.
Tuesday September 21, 2010 9:30 bob sherbin
9:32
bob sherbin:
it's clear, jhh says, that cuda's making deep inroads into most areas of science and engineering.
Tuesday September 21, 2010 9:32 bob sherbin
9:32
bob sherbin:
a decent-size announcement, jhh hints.
Tuesday September 21, 2010 9:32 bob sherbin
9:33
bob sherbin:
here it is: through pgi, we're announcing cuda x86. so you can deploy cuda apps on any computer or server in the world. this will open its use in a very big way.
Tuesday September 21, 2010 9:33 bob sherbin
9:34
bob sherbin:
JHH poses a question: how do we put the power of cuda in the hands of every engineer designer and researcher in the world. What else can we do to spread hpc?
Tuesday September 21, 2010 9:34 bob sherbin
9:35
bob sherbin:
the answer is: killer apps, he says
Tuesday September 21, 2010 9:35 bob sherbin
9:37
bob sherbin:
matlab is used by millions, as a general purpose numerical computation package. it has stats tool kits, image-processing toolkits, data-acquisition toolkits, informatic toolkits. matlap will support cuda-accelerated GPUs with the parallel computing toolkit.
Tuesday September 21, 2010 9:37 bob sherbin
9:38
bob sherbin:
matlab, he says, is the excel of engineering.
Tuesday September 21, 2010 9:38 bob sherbin
9:39
bob sherbin:
Next announcement: Multi-GPU AMBER11.
Tuesday September 21, 2010 9:39 bob sherbin
9:42
bob sherbin:
in computational biology, some of the simulations are enormously complex. like walking, gene sequencing. researchers are simulating molecules at the atomic level using quantum chemistry. AMBER11 is among the most popular molecular simulation packages. UCSD recently made this GPU capable.
Tuesday September 21, 2010 9:42 bob sherbin
9:44
bob sherbin:
really cool slide now of the Kraken supercomputer, it costs tens of millions and is the fastest amber machine. and there's a picture of jhh standing in front of it with a gpu-computer the size of a college dorm refrigerator that has the same amount of power. this makes supercomputing much more accessible.
Tuesday September 21, 2010 9:44 bob sherbin
9:45
bob sherbin:
what other fields, jhh asks, would benefit from extreme acceleration in hpc?
Tuesday September 21, 2010 9:45 bob sherbin
9:46
bob sherbin:
jensen says one is ansys, a simulator for engineers.
Tuesday September 21, 2010 9:46 bob sherbin
9:47
bob sherbin:
using algorithems, ansys can predict the behavior of product design. it's used by 97 of world's top 100 industrial companies. there are 35K customers in 40 countries. it was used, among other things, to design michael phelps olympics swimsuit
Tuesday September 21, 2010 9:47 bob sherbin
9:48
bob sherbin:
to talk about ansys, jensen brings on stage dr. s. subbiah, an ansys veteran exec
Tuesday September 21, 2010 9:48 bob sherbin
9:48
bob sherbin:
dr. s is a cool looking guy, pewter-colored hair, open collar dark suit
Tuesday September 21, 2010 9:48 bob sherbin
9:49
bob sherbin:
dr. s
Tuesday September 21, 2010 9:49 bob sherbin
9:51
bob sherbin:
....is talking about ansys being used on a 747's brake. if a 747 needs to brake for on an abortive takeoff, it requires stopping a huge plane going 200 mph within 5000 feet. sounds pretty complex to me.
Tuesday September 21, 2010 9:51 bob sherbin
9:52
bob sherbin:
dr. s is describing the phenomenally complex problems that his company's customers are trying to figure out by running them on clusters, which can take days per calculation.
9:53
bob sherbin:
on a quadcore chip, a speed up on a xeon machine could be more than 2x.
9:55
bob sherbin:
jhh asks, now that ansys will be using gpu's, where do you see simuation-driven product development playing out? Dr S: it will be multi-disciplinary.
9:55
bob sherbin:
another trend is that design is more democratically achievable. it's not just big companies that can figure out this stuff. someone in a garage can.
9:56
bob sherbin:
dr. s leaves the stage. |
