Seattle Code Camp

Saturday, April 17th, 2010

I’ve put the decks for today’s talks online you can download them. Due to the erupting volcano in Iceland Tiberiu Covaci couldn’t make Code Camp so Reed Copsey and I filled in the gaps. Talk Videos will be appearing here soon. Fast… Faster… FASTER! Adventures in ...

NBody.net Code Available

Friday, March 26th, 2010

I’ve dropped some of the code which makes up NBody.net to a BitBucket repository. This may not be the project’s final home but for now that’s where I’ll be dropping code for now. Currently there are two of the core libraries: NBody.DomainModel.Common – The core ...

Implementing a Parallelized Octree in F#

Wednesday, January 20th, 2010

  The result of all my F# hacking around over Christmas wasn’t just some notes on what not to do (my previous F# blog post). I actually got down to writing some more code for my n-body model in F#. I got down to reading some of “F# for Scientists” and ...

N-Body Modeling Pages Online

Thursday, September 24th, 2009

So I finally got around to putting some pages up about n-body modeling (link in nav bar above). Even if you’re not into numerical simulations, physics or any of that stuff some of the mixed language aspects of the code might be of interest. I’m not really ...

C# Optimization Revisited Part 3: The “Native Option” C++

Tuesday, September 1st, 2009

In part 1 and part 2 of my thread on C# optimization there was a lot of talk about algorithms and the like. The next two posts take a different tack… first re-implementing the same algorithm using different languages and then in a different language and hardware. It turns out ...

Mixed Languages: The Right Tool for The Right Job

Tuesday, June 16th, 2009

The N-body modeling code and visualization I’ve been working on finally got off the ground in some sort of reasonable form last night. Here you can see it running with 5000 stars at over 30 frames a second. It’s been working from the start (agile/TDD isn’t something you just write about) ...

N-Body Modeling and Technical Computing Resources

Thursday, April 16th, 2009

Someone asked for a list of resources on N-Body modeling. I had a bunch of links in my favorites so here they are. I also threw in some more on technical computing and writing high performance code.

C# Optimization Revisited Part 2: Concurrency

Wednesday, March 25th, 2009

In Part 1 of Optimization Revisited I considered, with the help of Bill Clinton, improving performance by using a fundamentally better algorithm rather than micro-optimizing an existing one. One thing that’s pretty obvious looking at the CPU usage on a  machine with more than one core is that even the ...
