Hi folks.
I would like to know which types of CUDA memory I can use with subj matlab object. More specifically I wonder if user can use constant or texture memory. I'm newbie in CUDA programming but AFAIK using such memory types requires code outside kernel, but this code (cpu code) is discarded by compiler with -ptx flag. Correct me if I'm wrong or forward some useful links.

Currently it's not possible to use either texture or constant memory with CUDAKernel objects. The memory caches in recent NVIDIA GPUs mean that many of the advantages of using constant memory are no longer so important.
Do you have a particular example of what you'd like to do with texture/constant memory?

I've read about LDU in Fermi arch, but it isn't clear for me in which cases values from global memory are cached. Could you give some explanations on that using my comment above?
As I understood there is no way to use textures?
