atomicCounterIncrement and imageAtomicExchange on GTX460?

  • I have a GTX460 with 768MB VRAM.
  • My OS is Ubuntu 14.04 LTS.
  • Display driver is “NVIDIA binary driver - version 346.96”.
  • “glxinfo | grep version”:

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 4.3.0 NVIDIA 346.96
OpenGL core profile shading language version string: 4.30 NVIDIA via Cg compiler
OpenGL version string: 4.5.0 NVIDIA 346.96
OpenGL shading language version string: 4.50 NVIDIA

  • MY QUESTION:
    Do the GLSL functions atomicCounterIncrement() and imageAtomicExchange() work as
    expected or are they some kind of ‘dummy implementation’ because the hardware doesn’t
    support them (hardware too old)?

Please help, I need to implement OpenGL GLSL stuff for a bachelor thesis.
