There have been huge advances in DNA sequencing technologies in recent years; e.g. Illumina has just announced the HiSeq X system which can sequence human genomes at a cost of only $1000 per genome. Besides population-scale human genome sequencing another important application of sequencing technologies is environmental sequencing (so called metagenomics). Metagenomic studies … [Read more...]
Nvidia Talks About ARM64 and 64-bit K1 SoC
The Hot Chips 2014 conference conveyed some hot information this week about Nvidia's 64-bit Tegra K1 -the first 64-bit ARM processor for Android devices that pairs the dual-core "Project Denver" CPU with Nvidia's 192-core Kepler GPU (a ceepee geepee). The ARM-based Denver CPU was custom designed by Nvidia and is compatible with ARM's 64-bit ARMv8-A architecture. The chip is … [Read more...]

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...]
