Continuing on to some cool applications of Eulerian paths. Intro Visualization GPU/CUDA Injection The goal of this little graph experiment remains exploration of accelerating Eulerian path finding on the GPU. This is the final introductory post. Eulerian Path Hierholzer algorithm works great. It's linear in the number of edges, so as fast as we can … Continue reading Walking the Euler Path: PIN Cracking and DNA Sequencing

Walking the Euler Path: GPU for the Road
Continuation of the previous posts: Intro Visualization GPU Digression I was going to talk about something else this week but figured I'd take advantage of the free-hand format and digress a bit. Continuing the travel metaphor and remembering Julius Cesar's "alea iacta", we'll talk about GPU algorithms, for which I invariably use my favorite Aela.CUDA … Continue reading Walking the Euler Path: GPU for the Road
Visualizing Graphs
Previously Walking the Eule Path: Intro Generating and Visualizing Graphs I can hardly overemphasize the importance of visusalizations. Many a bug had been immediately spotted just by looking at a visual of a complex data structure. I therefore decided to add visuals to the project as soon as the DirectedGraph class was born. Code & … Continue reading Visualizing Graphs
Walking the Euler Path: Intro
Source Code I'm thinking about a few posts in these series going very fast through the project. The source is on my GitHub, check out the tags since the master branch is still work in progress. Experimenting with Graph Algorithms with F# and GPU Graphs play their role in bioinformatics which is my favorite area … Continue reading Walking the Euler Path: Intro
GPU Split & Sort With Alea.CUDA
Implementing radix sort with Alea.CUDA using the Unbound module.
Capture Video in 2 Lines of Code
Literally. Well almost. 2 meaningful lines + some boilerplate. This has got to be easier than even Python! Using EmguCV, a wrapper around OpenCV and F# Interactive:
Look-and-say: [Alea.]CUDA
Continuing the Advent of Code theme from the previous post. Figured since this year is going to be my year of CUDA, this would be a good opportunity to take it for a ride. A good April 1st post, but why wait? So, how can we make this even faster than the already fast imperative … Continue reading Look-and-say: [Alea.]CUDA
Look-and-say: F#
This holiday season my brief indulgence was solving the Advent of Code puzzles. One was about the look-and-say sequence. It starts with "1" and grows as follows: 1 is read off as "one 1" or 11. 11 is read off as "two 1s" or 21. 21 is read off as "one 2, then one 1" … Continue reading Look-and-say: F#
Non-linear Thinking with CUDA.
I love GPU programming for precisely this: it forces and enables you to think about a solution in a non-linear fashion in more than one sense of the word. The Problem Given a set $latex A = \{a_1, a_2 \ldots a_n\}$, output a set $latex S_A = \{0,\ \sum\limits_{k=1}^{n} a_k,\ \sum\limits_{k=i}^{i + j \mod n} … Continue reading Non-linear Thinking with CUDA.
Turnpike Problem (F#)
The Problem This is a problem for which no polynomial time solution exists, although a pseudo-polynomial (polynomial in the degree of the maximum element) does exist. In this paper, the algorithm proposed for the sum-function with full information is simple enough. For the original problem with the difference funcition, the algorithm is simple as well: … Continue reading Turnpike Problem (F#)
