I *do* like it. At a certain point you write: "The code generation approach in Firedrake enables computer scientists to advance the compiler and parallelisation technology, independent of the numerics. Numericists to develop sophisticated discretisations independent of their implementation, and application specialists to deploy these numerics efficiently and effectively." Maybe you wanted a comma before numericists and not a full stop?

Hi all, This time with pretty pictures. Any comments before I send this in most welcome.

Promotional flyer draft.
by David Ham 07 Aug '14

The PRISM project (http://prism.ac.uk/) of which we are part, is developing two page flyers about each of the software packages in the consortium. We are producing the content, and a professional graphic designer will lay out the actual flyers. The target market is the steering committee of PRISM, which is primarily people from industry at the simulation user end of the spectrum. I think the flyer therefore needs to be something like "what can Firedrake do for you". Comments are sought on the attached text fragments. Some of us will also be making some pretty pictures for this this afternoon. -- Dr David Ham Departments of Mathematics and Computing Imperial College London http://www.imperial.ac.uk/people/david.ham

Firedrake on supercomputers
by Tuomas Karna 07 Aug '14

Hi all, I'm running my code on TACC Stampede and I have a couple of questions: How can I setup Firedrake/PyOP2 for the target machine, for example to use Intel compilers, target architecture (sandybridge) instruction set, or Intel MKL libraries? Until now I've only used MPI. What do I need to do to run with openmp or cuda for instance? I've got the PyOP2 dependencies in place, as they are listed on the Firedrake website. Also, does anyone have experience on using Intel MIC coprocessors with Firedrake? Cheers, Tuomas

Numba

Hello all, One of my badminton acquaintances asked if I'd heard of Numba <http://numba.pydata.org/> (wiki <http://en.wikipedia.org/wiki/Numba>, github <https://github.com/numba/numba>). It seems to have a role similar to that of Cython, while requiring even less intrusive changes to the code. Chances are that someone else on the list will have a better idea of whether we might be interested in using it in the future. There's a couple of blog posts here <http://jakevdp.github.io/blog/2012/08/24/numba-vs-cython/> and here <http://jakevdp.github.io/blog/2013/06/15/numba-vs-cython-take-2/> comparing Numba with Cython; they seem to have similar execution speeds so it's unlikely to be worth rewriting existing code. Andrew
