Sorry if this subject has been already dealt here. Which are some common tests for nonparametric k-way ANOVA? I have read about Kruskal-Wallis test as a kind of nonparametric one-way ANOVA, but I have not found anything about a general-setting (I mean k-way) nonparametric ANOVA. Can you recommend me a good R package (or other reliable software) for that? Looking forward to your answers, --

This is probably a stupid question... what do you need VRAM for anyways? In _theory_ it's an abstraction to talk about memory that's not accessible by the CPU. This is obviously not the case here, and presumably the GPU can access all the memory in the system, so it can be all treated as "GART" memory... AFAIK all accesses are behind the in-GPU MMU, so contiguous...
