There is a multicore platform that is currently concen-
trating an enormous attention due to its tremendous poten-
tial in terms of sustained performance: the NVIDIA Tesla
boards. These cards intended for general-purpose computing
on graphic processing units (GPGPUs) are used as data-
parallel computing devices. They are based on the Computed
Unified Device Architecture (CUDA) which is common to
the latest NVIDIA GPUs. The bottom line is a multicore
platform which provides an enormous potential performance
benefit driven by a non-traditional programming model.
In this paper we try to provide some insight into the
peculiarities of CUDA in order to target scientific computing
by means of a specific example. In particular, we show
that the parallelization of the two-dimensional fast wavelet
