I just found a recent paper on the topic of parallel simulation of computer systems. Christopher Schumacher et al., published an articles at CODES+ISSS in October of 2010 talking about “parSC: Synchronous Parallel SystemC Simulation on Multicore Architectures“. Essentially, parallel SystemC.
For my parental leave, I have just bought myself a Lego Mindstorm NXT 2.0 kit. It is not much fun for our youngest, who mostly gets a bit scared by a piece of Lego driving around making noises, but I hope to be able to use it to teach my older child (almost five) to program. Let’s see how that turns out. It looks hard to make the NXT environment provide the kind of Roborally-style programming blocks that I had hoped to create, as I cannot for some reason get a sufficiently custom icon onto custom blocks.
It also presented me with an opportunity to try some domain-specific high-level graphical programming. The programming environment provided for the NXT series of Mindstorms kits is based on LabView from National Instruments, and it really does seem to work. It even features parallel tasks, which I tried to use…
SCDSource ran a short but good article summarizing a few DAC talks that I would liked to attend. it mostly about the experience of long-term parallel programming research David Bailey in presenting results in the field…
Last year, FLOSS Weekly interviewed Jan Lehnard of the CouchDB project. I put up a blog post on this, noting that it was interesting with a scalable parallel program written in Erlang, a true concurrent language. The interview was interesting, but not very deeply technical. Now, almost a year later, the StackOverflow podcast, number 59, interviewed the founder of the project, Damien Katz. This interview goes a bit more into the technical details and what CouchDB is good for and what not, as well as some details on the use and performance of Erlang.
Last year in a blog post on video encoding for the iPod Nano, I complained about the lack of performance on my old Athlon. A bit later, I noted that (obviously) video encoding is a good example of an application that can take advantage of parallelism. Yesterday I put these two topics together in a practical test. And it worked nicely enough.
I keep looking out for interesting examples of parallel software, and there is constant trickle of these. This past week I spotted a couple of new ones in the EDA field: SPICE simulation and chip timing analysis.
