In a second step OMP2HMPP executes all variants to obtain the performance and power consumption of each transformation. The resulting trade-off can be used to choose the more convenient version. After running the tool on a set of codes from the Polybench benchmark we show that the best automatic transformation is equivalent to a manual one done by an expert. Compared with original OpenMP code running in 2 quad-core processors we obtain an average speed-up of 31 and 5.86 factor in operations per watt.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We present OMP2HMPP, a tool that, in a first step, automatically translates OpenMP code into various possible transformations of HMPP.
