Dear Wayne,
thank you! My code runs for a [1536,231,126] sample also very fast -
in 0.13 sec, but it's not for me. At a colleague's PC it lasts minutes
without caching the matrix to swap and he asked me for a possible
speedup. Unfortunately, I don't know which could be faster than
total... I cannot understand, why the fastest method to determine
whether a vector is entirely set to zero is based on total - a sum
method... I tried to increase speed by the use of the gpulib, but
also got the same effect. Any other ideas?

Best regards
