Hello everyone,
I have a buffer allocated in GPU memory:

buffer = CUDAMemoryAllocate["Double", 500];

then I do some operations with a function, then I take the buffer back
and compute the total of that array:

v = CUDAMemoryGet[buffer];
Total[v]

but the result I obtain with
CUDATotal[buffer]

is different...
why?

thank you all
