We present OMP2HMPP, a tool that, in a first step, automatically translatesOpenMP code into various possible transformations of HMPP. In a second stepOMP2HMPP executes all variants to obtain the performance and power consumptionof each transformation. The resulting trade-off can be used to choose the moreconvenient version. After running the tool on a set of codes from the Polybenchbenchmark we show that the best automatic transformation is equivalent to amanual one done by an expert. Compared with original OpenMP code running in 2quad-core processors we obtain an average speed-up of 31x and 5.86x factor inoperations per watt.
