Cache Locking in C++
|
Ignore the obvious problems that this may occur, but does anyone know a way to keep (lock) data in the processor cache, using C/C++?
My research involves profiling scientific computations, and my application seems to be experiencing many cache mis... |

Has anyone else experienced this problem? I have a multi-dialog MFC app, that has a dialog which uses DirectX9 to generate a display. When running a debug build, everything works fine, focus changes are handled, other dialogs can be opened and closed... |

UK Game Selection

I'm from the UK, where there is, in my opinion, a terrible selection of games to choose from. They all appear to be the same. So I was wondering, what has caused this to happen?
Last weekend I was recommended to and subsequently bought a game for... |

Should Windows come bundled with a programming language?

I was fortunate to grow up when computers came with programming languages (usually a BASIC variation), and that helped spawn my interest today.
Should modern day PC's come with some form of language to allow the less experienced to grasp the basi... |

UK Games Industry, What do you think?
|
The UK used to be a major player in the games industry, I dont feel this is the case anymore. What do other people think? Is the UK games industry booming and on the up, or is it doomed to succumb to the USA and Japan giants? |

How do I load a file through the cmd line in a win32 app?
|
At the command line "your_app.exe something.file"
In windows, drag a file onto your binary.

How To: Simple AI

I would suggest calculating a vector based on the position of the enemy ships and all other objects on screen. The magnitude of this vector would be equal to "threat". Summing all of the vectors would give you an approximate direction of th... |

Very nice! Well thought out.
It would be nice if we could sort so the free resources show up first, but I suppose that might affect any future sponsorship deals! |

Cache Locking in C++

I have dabbled in a bit of OS devving / processor development before, and of course Antheus you're right. But it just seems odd that even a Windows OS would reject data from the cache so haphazzardly.
It also occured to me that perhaps the system... |

There aren't opcodes for controlling such low-level hardware details. You should run your program in a simulator to that gives you access to this kind of virtual cache information.
Is that so? Surely this feature w... |

New brain computational theory combining AI research, Neuroscience and Psychology

dsanjit, I believe you may have missed the point of my argument a little.
Firstly, I am in complete agreement with you about the current state of AI. But in fear of attracting a tidal-wave of flaming(!), I suggest that computer-based AI research i... |
