Hi,
I am confusing in checking the Bytes of gpuArrays. It seems every varaible's Bytes is 4. Could I do something more to set it well? Or it is a windows or Geforce problem that I could not check it correctly?
x= 1:5;
xg = gpuArray(x);
xg32 = gpuArray(int32(x));
whos xg
% Name Size Bytes Class Attributes
% xg 1x5 4 gpuArray
whos xg32
% Name Size Bytes Class Attributes
% xg32 1x5 4 gpuArray

Unfortunately, whos does not currently report the number of bytes used by a gpuArray on the GPU - the 4 bytes you see reported is the amount of CPU memory consumed. The number of bytes used by a gpuArray is essentially the same as the number of bytes used by the corresponding CPU array. (The only time this is not the case is for a non-square sparse gpuArray - the different sparse layouts makes a difference).
