Ubuntu kernels: is anyone paying attention???

I have noticed this now on my laptop, on JackRabbit, on a few other systems. The Ubuntu kernels are thrashing with context switches. 4000-5000 or so per second, and fast machines are rendered sluggish. So we build our own. Did that for Ubuntu thus far, and it has been good. Context switches per second down […]

Last time, on as the FOSS turns, …

What I don’t get is why the powers that be sought to invent yet-another-new-cooling-solution-requirement that does a good job of fragmenting the market, and insuring limited supply of reasonable cooling systems.

MPI Class

I taught the first half of an MPI class for a university last friday. It was fun, I showed them how to engineer an application for maximum scalability, as well as how to do basic message passing. There isn’t a great deal we can do in a single day, but I did start to get […]
