As you see, we haven't got speed acceleration, parallel version working longer than sequential. That's because cost of MPI_Gather/MPI_Scatter operations bigger that cost of sum. But if we change sum ...

Abstract: This paper demonstrates that parallel vector curves are piecewise cubic rational curves in 3D piecewise linear vector fields. Parallel vector curves—loci of points where two vector fields ...

Abstract: Feature extraction is an essential aspect of scientific data analysis, as it allows for a data reduction onto relevant structures. The extraction of such features from scalar and vector ...
