Hammad, Andrew, Professor Negrut, and I (Aaron) recently returned from a trip to GTC Asia that can be described as nothing short of enlightening. Oftentimes surreal and occasionally fubar (fun beyond all recognition), Beijing treated us to a range of interesting experiences that cannot be adequately described in a mere news post such as this; but here's an inadequate description anyways. Technology was the focal point of our journey, both within and without the conference. Whether it be pumping up the crowd with Professor Negrut's presentation on the use of GPUs for mechanical engineering applications (presentation slides found here: http://developer.download.nvidia.com/GTC/PDF/2103_Negrut.pdf, commentary found here: http://blogs.nvidia.com/2011/12/gtc-asia-wrap-up-with-flurry-workshops-lectures/ and http://www.heise.de/ct/artikel/Spielekonsolen-und-Supercomputer-1399235.html), or observing Steve Scott (Nvidia CTO and UW alumni) discuss the prospects of achieving exaflop computing, cutting-edge tech was ever present. Topics at GTC ran the full gamut of HPC-related applications including weather modeling and bioinformatics, to informational/instructional talks pertaining to parallel programming and related initiatives. Of the large quantity of sessions, we were intrigued mostly with PGI's discussion on their Accelerator compiler product, which provides directives to more easily/automatically parallelize code structure and add CUDA as necessary. See a list of featured sessions from GTC here: http://insidehpc.com/category/hpc-hardware/gpus/. As mentioned earlier, this focus on technology was not limited to the halls of the China National Convention Center (GTC); we took tech to the streets you see. Believe it or not there is a city within the Beijing sprawl known as the “Electronic City”, Zhongguancun. We ventured over there after a rousing tour of the Forbidden City and a Han-era Human Resources office (funny story; the lesson here is don't buy cheap tickets for the “secret entrance”). Zhongguancun was a nerd Mecca of sorts, with multiple many-story malls that contained pretty much everything you could need as a greasy computer dweeb (except for a big bag o' lasers; Andrew tried but couldn't find one for some reason...). The place felt like a bazaar, with loud bartering emanating from every corner of the room; a sea of redundant booths and general techno craziness. There was even some cutting-edge stuff that hadn't hit the American market yet; our colleague Hammad somehow managed to get his hands on an IPhone 5G for only $30! There is much more to discuss, but in summary, I'll say that not only was GTC a blast, I've also discovered how exciting Beijing is in terms of technology, research, and knowledge. The urge to innovate is ubiquitous and the place is ripe for it (both resource-wise and visually; think William Gibson). While I sit here writing this, my souvenir, porcelain effigy of Mao gives me an encouraging thumbs-up from a distant corner of my desk (the rest of his fingers broke off). Perhaps its just that heart-melting smile on Mao's crudely-cast face, but I truly feel reassured that Beijing is amazing. Hopefully we can return someday.

Phillip hahn joined the Simulation-Based Engineering Laboratory (SBEL) in September 2008 and his project is working on the development of a discrete element based simulation method for sound propagation. Bio:I study mechanical engineering in Germany at the University of Stuttgart but currently I am graduate student at the University of Wisconsin-Madison because I received a scholarship from the Institute for Machine Tools (IfW) of the University of Stuttgart.Every year three students from Stuttgart have the opportunity to study in Madison and to receive a masters degree there. The scholarship is funded by the German Academic Exchange Service (DAAD) and it will last nine months.My project at the SBEL will be my master thesis and I will investigate an application of the Discrete Element Method to sound propagation. It will be one of the main challenges of this project to determine the necessary properties of a discrete element model of a liquid or gas in order to obtain accurate results.

Justin Madsen and Dan Negrut start working on a project that will determine the effect of variable inputs on the dynamic behavior of an off-road vehicle. ADAMS/Car is used to create a realistic HMMWV vehicle model, and FTire is used to model the tire/road interactions. Road profiles and vehicle suspension parameters will be varied and compared to baseline simulations to gauge how each variable affects vehicle dynamics.

Graduate students Justin Madsen and Yakira Braden both received Wisconsin Space Grant Consortium Graduate Fellowship grants for 2008-2009. Justin will be working on implementing tracked vehicle simulations to validate a novel fixed-point iterative process to determine contact forces. He then hopes to implement his simulations on commodity graphics cards to incorporate sand dynamics into his tracked vehicle simulations.
