The following figures depict the performance benchmarks of several BLAS1 and SpMV routines, using the PARALUTION library on multi-core CPU, NVIDIA GPU, AMD GPU and Xeon Phi (MIC) . All results are obtained in double precision.

Furthermore, a non-preconditioned CG is performed on a Laplace matrix resulting from a finite difference discretization of the unit square with 4.000.000 unknowns.

In the next plot we compare only best setup for all configurations.
