Are you able to use CUDA on Linux?

I am using Mathematica 10.2 on Ubuntu 15.04 x64. At first, I try to use CUDALink: Needs["CUDALink`"]; CUDAQ[] It returns False. The reason why it returns False is that the default paths for NVidia Driver and CUDA are /usr/lib64/libnvidia-tls.so…

How to make a volume CUDA rendering isometric?

I just realized that the output of CUDAVolumetricRender[] uses (quite marked) perspective, which I do not want (for scientific data representation, it can be very misleading). How do I turn it off? (i.e. make it use an isometric projection)

Can CUDAVolumetricRender be combined with other 3D graphics?

I have volumetric data, which I can render using CUDAVolumetricRender[]. However, I cannot seem to find a way to combine it with other 3D graphics, such as adding a bounding box, axes, labels, etc. How is CUDAVolumetricRender[] supposed to be…

CUDA: setting grid dimensions

I'm new to CUDA, and CUDALink. I see how CUDAFunctionLoad allows one to set the block dimensions. On calling the function, you can also either pass as argument or have MMA automatically select the number of threads to be launched as the max length…

cannot load CUDAFunction from cubin, ptx or library file

According to the documentation of CUDAFunctionLoad it should be easy to specify a compiled file (cubin, ptx, dll should all work) as the source for loading a CUDAFunction. Unfortunately it does not for me. Compiling from source works fine, but as…
