Breadth-First Graph Search Uses 2D Domain Decomposition – 400 GTEPS on 4096 GPUs
Parallel Breadth-First Search is a standard benchmark and the basis of many other graph algorithms. The challenge lies in partitioning the graph across multiple nodes in a cluster while avoiding load-imbalance and communications delays. The authors of the paper, "Parallel Breadth First Search on the Kepler Architecture" utilize an interesting 2D decomposition of the graph … [Read more...]
Deep-learning Webinar Demonstrates Handwriting Recognition and Efforts to Teach Drone to Fly Down a Wooded Path
Deep-learning is a computational expensive but rewarding method to solve many complex pattern recognition problems. The recent NVIDIA webinar by Dan Claudiu Cireșan, Senior Researcher at the Dalle Molle Institute for Artificial Intelligence (IDSIA) in Switzerland highlighted some of the capabilities of deep-learning for image recognition problems such as handwriting recognition … [Read more...]

Harvard Origami Robots Fold Themselves and Walk Away
Okay, this is cool (albeit slow if you watch the timeline in the video). Researchers at Harvard and the Massachusetts Institute of Technology demonstrated how a single thin sheet composed of interconnected triangular sections could transform itself into a boat or plane shape — without help. The findings were published in the Proceedings of the National Academy of … [Read more...]
