Slides and demos (in Jupyter Notebook form) for all the courses I currently teach on an ongoing basis at the University of Illinois are now available in open source form on Github:

• Numerical Analysis (for CS450)
• Numerical Methods for Partial Differential Equations (for CS555)
• Fast Algorithms and Integral Equations
• Languages …

As someone who maintains a fair number of software packages that build, in one way or an other, on OpenCL (and keeps creating more!), a friend recently asked me what I thought of the state of the OpenCL ecosystem in 2018. In part, I am writing this to support the …

Nvidia’s Parallel Forall blog recently highlighted two applications that are using my Python HPC packages to accelerate their computational science workloads:

• Increasing the Luminosity of Beam Dynamics with GPUs, a writeup of Adrian Oeftiger‘s work on CERN’s PyHEADTAIL code.

• Open, Reproducible Computational Chemistry with Python and CUDA …

At SC15 last week I had the opportunity to present a tutorial on how to design, build, and compile your own domain-specific language using Python. I am now releasing the tutorial material under a Creative Commons license for the community to use and build on.

Specifically, the material …

Gaston Hillar has written a very nice introductory article on using PyOpenCL, to be part of a two-part series. I’m already looking forward to the second part. :)

If you’d like to try to follow along with the article, check out the OpenCL installation howto, then follow the easy …

As someone who, on occasion, has created a domain-specific-language or two, this entry of the Devil’s Dictionary of Programming hit close to home:

DSL

A domain specific language, where code is written in one language and errors are given in another.

Simon McIntosh-Smith from Bristol University just let me know that he and Tom Deakin have published a new set of lecture slides and excercises (with solutions!) to teach (more generally) OpenCL and (specifically) PyOpenCL. I’ve added a link to this and a few older tutorials to

PyOpenCL’s main …

Quote of the day:

In Python 2.6, no one can hear you scream.

(source) This reminds me of that one time when I was debugging some odd interaction between threading and contexts in PyCUDA. Never again, hopefully. :)
