3.3.3. Stream Benchmark

The stream benchmark is part of the HPC Challenge benchmarks (http://icl.cs.utk.edu/hpcc/) and here we present two versions: one that inserts barriers and another without barriers. The behavior of version with barriers resembles the OpenMP version, where the different functions (Copy, Scale, …) are executed one after another for the whole array while in the version without barriers, functions that operate on one part of the array are interleaved and the OmpSs runtime keeps the correctness by means of the detection of data-dependences.
