Faster approach for total(data,dimension) possible? [message #67074]

Hi,
i'm looking for a faster approach to do the following:

data=rebin(dist(100),100,100,50,/sample)
mask=total(data,3) gt 0.

Depending on the size of data and on the hardware of the client the
code above runs too slow for me. I'd like to find all pixels in a
hyperspectral application, which bands are not zero. The result should
be a mask with the same 2D-dimensions as original data for further
processing.

Thank you and best regards

CR
