...ws using OpenGL textures. So, to begin with, I have a process that spans child processes (*not* threads, i.e. using the fork system call) Each one of these (multi)processes has a video decoder that produces bitmaps at 25 fps rate. I am dumping the bitmaps to openGL using pixel buffer objects (PBOs) and textures. Each time when uploading a PBO and later on, when showing the texture, each (multi)process needs to change to its own context by performing the GLX call glXMakeCurrent(display_id, window_id, context_id) So there is quite a bit of context switching going on..! If there are 30 w...

Hello again. Today I got following question: What is the purpose of DIB Engine? Is it to speed up DirectDraw apps, or is it to add missing functionality for DirectDraw ?emulation?? I'm asking this because I recently tested few DDraw apps (Fallout2 and Happyland Adventures) with DIB enabled and... well for HA there was now significant speed difference, and Fallout2 slowed down even more :( .

...is a 64-bit bitmask of threads (plugin classes) that could touch this memory). I wouldn't try to modify the existing AddressSanitizer.cpp, but would write a new pass for your thesis. If you need help with the asan code -- just ask. --kcc On Wed, Sep 26, 2012 at 2:56 PM, Peter Boström <pbos at kth.se> wrote: > Hi llvm-dev! > > I'm writing my master's thesis on sandboxing/isolation of plugins > running in a multithreaded environment.

Hi llvm-dev! I'm writing my master's thesis on sandboxing/isolation of plugins running in a multithreaded environment. These plugins run in a real-time environment where the cost of IPC/context switching and being at the scheduler's mercy is not an option. There can be a lot of plugin instances running and all have to perform some computations and return the result to the main thread
