CUDA: WEEK IN REVIEW

Welcome to CUDA: WEEK IN REVIEW, a news summary for the worldwide CUDA, GPGPU and parallel programming community.

NEW: NVIDIA Tesla K20 Now Available for Pre-Order. Tesla K20s for cluster nodes and workstations are available for pre-order today. With over 1 TF double precision performance, Tesla K20 is the world’s fastest and most energy-efficient GPU accelerator. Seehttp://www.nvidia.com/object/where-to-buy-tesla.html.
GTC 2013 UPDATE: Call for Posters is now open. This is a great opportunity to share innovative research topics in the areas of GPU computing, computer graphics, cloud graphics and game development. Visit the Call for Posters page.
CUDA TECH TIP: When debugging code or outputting results, the first go-to for any programmer is usually C’s trusty printf() command. Did you know that CUDA allows printf() directly from a GPU kernel? Read more.
CUDA SPOTLIGHT
GPU Power for James Bond This week’s Spotlight is on Mark Jaszberenyi, co-founder of Colorfront in Budapest, Hungary. Colorfront’s CUDA-accelerated technology powered the production workflow for the new James Bond 007 movie, Skyfall, which opens today in the U.S. Read the interview with Mark Jaszberenyi.

Watch the live web stream on the NVIDIA SC12 event page. For more info, visit www.nvidia.com/sc12. Petascale Earthquake Simulation ONERA, the French Aerospace Lab, will host a seminar on Nov. 19 in Chatillon, France on "Petascale Earthquake Simulations" by Prof. Yifeng Cui, San Diego Supercomputer Center. For info, contact thle@onera(dot)fr and gdenis@onera(dot)fr. Abstract: "Earthquake system science seeks to provide society with better predictions of earthquake causes and effects. Toward this goal, we have developed a highly scalable 3D finite difference code called AWP-ODC that has achieved "M8", a full dynamical simulation of a magnitude-8 earthquake on the southern San Andreas fault. This code was implemented with CUDA-MPI to allow efficient utilization of accelerators on hybrid GPU systems." NVIDIA Nsight 3.0 Visual Studio Edition Preview The new NVIDIA Nsight 3.0 Visual Studio Edition preview release supports CUDA 5.0 and the Kepler architecture in Tesla K20, with full CUDA Dynamic Parallelism debugging support and tracing of parent/child kernel launches. Available to registered Nsight developers. See:https://developer.nvidia.com/nvidia-nsight-visual-studio-edition NVIDIA Developer Forums The new NVIDIA developer forums are now live.

CUDA TECH TIP	back to the top
Output from a GPU Kernel with printf(): When debugging code or outputting results, the first go-to for any programmer is usually C’s trusty printf() command. Did you know that CUDA allows printf() directly from a GPU kernel? All the usual format specifiers are supported, and every thread can call printf() independently. If you only want to output something once, however, then you must conditionally choose a thread. The following example shows how it works:
__global__ void helloCUDA() {     if(threadIdx.x == 0)        printf("Hello CUDA from...\n"); // Only thread 0 will print this     printf("Thread %d\n", threadIdx.x); // Every thread will print this }
Note that printf() in device code requires a GPU with Compute Capability 2.0 or later.
