My Favorites from GTC 2012

I had a great time at GTC 2012; there was incredible energy and excitement from everyone I talked to. I think the energy level had a lot to do with all of the exciting technology announcements from NVIDIA (KeplerGK110 architectureCUDA 5NSight Eclipse EditionVGX, and GeForce Grid, to name a few!), but I think that having heaps of great content from outside contributors as well as NVIDIA was crucial to making GTC 2012 a great conference.

I was very busy at GTC and so I didn’t get to attend many of the talks that I wanted to see, and I’m sure the same is true for most attendees. Thankfully the GTC team created GTC On Demand to solve this problem.  With GTC On Demand you can watch almost any GTC talk, free, on the web. In the past month or so since GTC, I’ve been catching up on some of the great talks that I missed. In this post I want to share with you my favorites from GTC, and I hope you will share your favorite GTC talks in the comments.

In the Trenches at GTC: Faster Finite Elements for Wave Propagation

By Kenneth A. Lloyd (GTC 2012 Guest Blogger)


Geophysical wave propagation is really interesting because you can’t actually see the phenomenon, and you can only feel a small part of it (that is, unless you are unlucky and find yourself in the path of an earthquake). The only way we have of understanding the causes and effects of seismic activity is to model it, compare it with a lot of data, and visualize the mathematical model in a computer.

The problem, of course, is that the models, the data and the translation into some type of visualization are “computationally expensive”, meaning that it requires substantial computing power to crunch the numbers. Since seismic activity is not a planned event, we simply can’t wait for hours and weeks for the simulation to run to predict the far-reaching and potentially disastrous global effects.

In his GTC session on Thursday, May 17, Max Reitmann of the Institute for Computational Science in Lugano, Switzerland, showed us how seismic simulations are being done more quickly and accurately using CUDA and massively parallel processing. Reitmann detailed a Fortran, C/CUDA and MPI approach to a finite element implementation of wave propagation in geophysics. Specifically, the seismic propagation of earthquake perturbation. Reitmann employed an MPP CUDA graph coloring refinement of an existing, open source, seismic finite element analysis application—reducing the computational time from 75 hours to one hour.

There are two available approaches, depending upon the phenomena to be modeled: a seismic approach for earthquakes (which are non-experimental) and a tomographic approach (small perturbation models). The model and simulation yields a coarse-grained understanding of either global or local seismic phenomena in an economically reasonable time.

In the Trenches at GTC: Inside Kepler

By Tomasz Bednarz (GTC 2012 Guest Blogger)

I had been eagerly anticipating the “Inside Kepler” session since GTC 2012 opened. On Wednesday arvo, May 16th, two NVIDIA blokes, Stephen Jones (CUDA Model Lead) and Lars Nyland (Senior Architect), warmly introduced the new Kepler GK110 GPU, proudly announcing that it is all about “performance, efficiency and programmability.”

Lars and Stephen revealed that GK110 has 7.1B transistors (wow!), 15 SMX units, >1 TFLOP fp64, 1.5MB L2 cache, 384-bit GDDR5 and PCI-Express Gen 3. NVIDIA looked high and low to reduce power consumption and increase performance, and after many months of tough design and testing in their labs, the NVIDIA mates emerged with an awesome GPU that greatly exceeds Fermi’s compute horsepower, while consuming less power and generating less heat. Corker of a GPU!

In the Trenches at GTC: Swift: A GPU-based Smith-Waterman Sequence Alignment Program

By Jike Chong, Parasians (GTC 2012 Guest Blogger)

This week at GTC, Pankaj Gupta, a bioinformatics application developer at St. Jude Children’s Research Hospital, presented his work in the area of sequence alignment. Sequence alignment is an important component of bioinformatics that is crucial for the vision of personalized medicine. Sequence alignment matches new sequences to known sequences, while detecting point mutations, insertion mutations or deletion mutations for important initiatives such as finding better cures.

Current sequencing machines produce reads of gene samples through optical or electrical means. The read signals are converted into sequences of symbols called “bases” through machine-specific signal processing analysis, otherwise known as “primary analysis”. Machine agnostic sequence alignment algorithms are then applied to interpret the read sequences in the context of known sequences. Continue reading

In the Trenches at GTC: Scaling Applications to a Thousand GPUs and Beyond

By Adnan Boz (GTC 2012 Guest Blogger)

Question: Why would you need 50 petaflops of horsepower and a 500,000 scalar processor capable supercomputer?

Answer: You need to simulate dynamics of complex fluid systems!

On Day 3 of GTC, HPC architect and Ogden prize winner Dr. Alan Gray from the University of Edinburgh described his use of C, MPI and CUDA on an NVIDIA Tesla -powered Cray XK6 hybrid supercomputer to run massively parallel Lattice-Boltzmann methods.

“Simulating simple fluids like water requires massive amount of computer power, but simulating complex fluids like mixtures, surfactants, liquid crystals or particle suspensions, requires much more than that,” commented Dr. Gray. Continue reading

In the Trenches at GTC: CUDA 5 and Beyond

By Michael Wang, The University Of Melbourne, Australia (GTC 2012 Guest Blogger)

Following up the opening keynote by NVIDIA CEO and co-founder Jen Hsun-Huang, Mark Harris took the very same stage (albeit with a more intimate crowd) for his afternoon session entitled CUDA 5 And Beyond.

Mark walked us through the major features of the upcoming CUDA 5.0 release, and took some time to share a vision for the future of GPU and massively parallel programming generally.

The four aspects of CUDA 5 that Mark highlighted were:

  1. Dynamic parallelism
  2. GPU object linking
  3. NVIDIA Nsight, Eclipse Edition
  4. GPUDirect for clusters (RDMA) Continue reading
