  • How to fix threading errors

    Updated: 2011-12-15 10:18:30
    I know I’ve had the experience of having a particular technical problem and having to try lots of different tools to find one that can solve it for me. It can be frustrating, because a lot of the time you’re experimenting to get to know the tool, rather than actually putting it to work to [...]

  • Four ways that task-based parallelism increases performance

    Updated: 2011-12-14 00:05:09
    I’ve heard a lot of people advocating task-based parallelism over the last couple of years, the idea that the code should be abstracted away from cores and threads and packaged into tasks which can be run across the available resources. Shannon Cepeda has written a short but interesting blog post on Intel Software Network, outlining [...]

  • How to write multicore games for PS3, Xbox 360 and PC

    Updated: 2011-12-13 16:16:23

    If you’re a programmer, you might have the right mindset and skills for a career in the secret service. That’s why GCHQ, one of the three UK Intelligence and Security Agencies, has set up an online puzzle called ‘Can you crack it?’, inviting people to crack the code they’ve created. It’s a screenful of hex [...]

  • Mixing MPI and MCAPI

    Updated: 2011-12-06 11:36:51
    You might remember I blogged previously about the Multicore Communication API (MCAPI), an API for multicore communication providing source level portability, and targeting closely distributed computing which means multiple cores on a chip and/or multiple processors on a board. The gentlemen from the Multicore Association whom I interviewed for that post, Sven Brehmer and Markus Levy, [...]

  • Taking your first steps in parallel programming

    Updated: 2011-12-05 14:21:22
    There’s a line that’s usually attributed to Goethe: “Whatever you can do, or dream you can do, begin it. Boldness has genius, power, and magic in it!” Leaving aside the fact that the Goethe Society of North America reportedly spent two years trying to find out if it really does come from Goethe and couldn’t [...]
