memory leaks

You are currently browsing articles tagged memory leaks.

Last month I mentioned gDEBugger being free and the joys of cppcheck. Here are some others that have crossed my path for one reason or another. Please do let me know (and so let us all know) about any worthwhile tools and libraries I haven’t blogged about – part of the reason for putting out this list is in hopes of learning of tools I haven’t heard of yet.

  • There is now a free version of AQTime, a commercial application that finds memory leaks and performance bottlenecks.
  • The Intel Graphics Performance Analyzers are supposed to be good stuff, and free – you just sign up for the Visual Adrenaline Program. I haven’t used them, but know people that have (hey, there’s Dan Baker on Intel’s page – nice).
  • Intel’s Parallel Inspector, despite its name, is particularly strong at finding memory leaks in any programs. Free month trial.
  • NVIDIA’s Parallel Nsight, also despite its name and focus of its advertising, is not just for CUDA and DirectCompute debugging and analysis, it also works on DirectX 10 and 11 shaders – you’ll need two machines networked together, one to run the shader and the other to control it. The Standard version is free, though when you sign up for it you also get a time-limited “we hope you get hooked” Professional license. Due to a currently-goofy pair of machines in my office (on different networks, and one’s a Mac I use purely as a Windows box), I haven’t gotten to try it out yet, but the demos look pretty great.
  • The Windows Performance Analysis Tools are evidently worthwhile for checking coarse-grained performance and bottlenecks for Windows programs. Again, free. I’ve heard that a number of groups have used xperf to good effect.
  • On an entirely different subject, HLSL2GLSL does a good job of translating most DirectX 9 (only) HLSL shaders to – wait for it – GLSL. Open source, and more info here, which discusses related efforts (like Mojoshader) and translation in the other direction.
  • Not really a tool per se, but still cool to see: here’s a way to find out how much free GPU memory is left for your OpenGL application. Anyone know any way to do this sort of thing with DirectX and Vista/Windows 7?
  • Will WebGL take off? Beats me, but it’s nice to see there’s an inspector, similar to gDEBugger and PIX.
  • GLM is a C++ math library particularly well-suited for use with (but not at all dependent on) OpenGL.
  • Humus points out that the old workhorse PIX now has new functionality that lets you assign names to objects, making debugging easier.
  • While I was messing with his binvox and viewvox programs, Patrick Min pointed out there’s a free 3DS file format library out there, lib3ds. I tried it out and it did the job well, taking very little time for me to integrate into my own private copy of binvox.
