cudaArray, used size and layout

[Robert_Crovella]

@lnwirz

Is there any documentation on the amount of memory that is occupied by allocating a cudaArray as a function of type/width/height/depth?

I’m not aware of documentation on these subjects. cudaArray is generally billed as “opaque”.

@lnwirz

If not, does there exist a function that returns the result (even without explaining how it got there)?

Not that I know of. I think you could probably easily enough lower-bound the size, don’t know if that is useful.

@lnwirz

Out of curiosity, is there any official documentation of the internal layout of a cudaArray (clearly I’m not indexing into it or such…)?

Not that I know of.

You can request changes to the CUDA documentation by filing a bug.
