This year’s GPU Technology Conference is in San Jose which is pretty much my part of the World so I thought I’d talk a busman’s holiday in mid-September and check it out. There’s several pre-conference tutorials on the basics of CUDA, DirectCompute, OpenCL as well as a ...

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 ...

My talk, “Fast… Faster… FASTER!” got accepted at Seattle Code Camp. I’ll be speaking at 10:15 on Saturday 17th. In a rare display of organization I’ve even started writing the deck with a little help from Banksy on the graphics. I’ll also be putting some more of the source code ...

Need to know how big the caches are on your processor? You could wade through the copious documentation on Intel or AMD’s web sites. It turns out this is no fun at all. I did this last week and still didn’t have the answer after skimming several white papers. ...

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 ...

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.

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 ...

As part of my journey in technical computing I’ve been writing a gravitational N-body simulation. Turns out you learn a thing or two about optimization when building numerical simulations that need to run as fast as possible. First off I used Vance Morrison’s code timer library to run multiple ...

Which uses more power, the AeroCool Green Home Server or a 40 Watt light bulb? You guessed it, the light bulb looses.
A few hours playing with a Smart-Watt meter hooked up to my home server I came up with some power usage numbers. While idle the Home Server consumes less ...

So having successfully put together a home server my mind started to wonder to desktop super computing and gravitational modeling. Which is when I came across this... Building home linux render cluster "24 cores that run each at 2.4 Ghz, a total of 48GB ram, and just need 400W ...
