In my opinion, GPU computing is significant because I—as a grad student—can easily afford a machine that allows me to perform a simulation like the following in 40 minutes instead of a whole workday. That’s why.

If you’re curious, this shows the density of a vortex …

Nicolas Pinto, Yunsup Lee, Bryan Catanzaro, Paul Ivanov, Ahmed Fasih and I have recently submitted an article that explains how PyCUDA allows the user to do run-time code generation (“RTCG”), and how that is an enormous boon to implementation efforts of most high-performance codes. Among many other things, PyCUDA also …

As a math person, you’re often faced with the task of communicating about math. Unfortunately, most modern means of communication, be it email, the web or instant messages, aren’t really suited to typing math. Fortunately, however, many of these means do allow the use of Unicode, and Unicode …

Here’s a waste of time I could just not resist: MIT‘s Project SIMILE has released a rather nice Timeline Web Widget. Combine that with GitPython and a bit of glue code in Python, and you get a neat, one-page summary of the software work I’ve done as …

Nicolas Pinto at MIT was nice enough to invite me over to give a talk in their CUDA class. I made a bunch of slides that I think are of general interest to people who are interested in PyCuda. You can find them here.

In this recent paper, Finite Volume guru Randall J. LeVeque addresses an issue that is near and dear to my heart: Computational Scientists must start thinking about the reproducibility of their results.

Scientific results obtained by experimentation are expected to be reproducible. This has long been demanded of published results …

I’m happy to announce the first truly public release of Synoptic, my own web-based dynamic note taking application. If you find yourself lost in a jumble of either paper notes, text files on a hierarchical file system, or an overgrown Tomboy wiki, and find yourself craving order, categories, and …

You might have been trying to implement the new-style VTK XML file formats. And you might have realized that what they tell you in the file format “specification” is just incomplete. Well, here are a few bits of information missing from there:

Binary Blob Header: In front of every binary …
