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...]

The authors noted "The experiments in this study show that the results reach up to 24 times speedup comparing to the CPU … [Read more...]
Accelerating the Traveling Salesman Problem with GPUs and Intel Xeon Phi
The traveling salesman problem (TSP) is an important computer science optimization problem with numerous real-world applications. There is a huge body of literature on TSP solutions. Following are a few GPU and Intel Xeon Phi accelerated solutions. TSPgpu TSPGPU v2.1 is a GPU-accelerated heuristic solver for the symmetric Traveling Salesman Problem with up to 32767 … [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...]
