Hi Andrei,

OFC you are right. I changed the computer and I totally forgot to install CUDA. But since the the GeForce is new I need to download VMD 1.9.2. apparently to get rid of my last error:

Info) Multithreading available, 8 CPUs detected.
Info) Creating CUDA device pool and initializing hardware...
CUDA error: invalid device symbol, CUDAClearDevice.cu line 62
Info) Detected 1 available CUDA accelerator:
Info) [0] GeForce GT 750M 2 SM_3.0 @ 0.93 GHz, 2.0GB RAM, KTO, OIO, ZCP
Info) OpenGL renderer: NVIDIA GeForce GT 750M OpenGL Engine
Info) Features: STENCIL MDE CVA MTX NPOT PP PS GLSL(OVF)

This was already discussed here I think:

Hi Max,

Have you installed CUDA from nvidia website? https://developer.nvidia.com/cuda-downloads
I am not sure for OSX, as I don't have a mac anymore, but on Linux I had to install CUDA before being able to use it.

Andrei

Hi there,

I have a NVIDIA GeForce GT 750M on Mac OS X and when I start the CUDA version of VMD I get the following message:

Warning) Detected a mismatch between CUDA runtime and GPU driver
Warning) Check to make sure that GPU drivers are up to date.
Info) No CUDA accelerator devices available.
Info) OpenGL renderer: NVIDIA GeForce GT 750M OpenGL Engine
Info) Features: STENCIL MDE CVA MTX NPOT PP PS GLSL(OVF)
Info) Full GLSL rendering mode is available.
Info) Textures: 2-D (16384x16384), 3-D (2048x2048x2048), Multitexture (8)

Does anybody has an idea how I can enable CUDA? The GPU is farely new so I don’t understand what the message with old drivers means.

Thank you,

Max
