2015 FIVB Volleyball World Grand Prix in the article below. Match won 3–0 or 3–1: 3 match points for the winner, 0 match points for the loser Match won 3–2: 2 match points for the winner, 1 match point for the loser The statistics of each group follows the vis reports P2 and P3. The statistics include 6 volleyball skills, serve, receive, set, spike, block, and dig. The table below shows the top 5 ranked players in each skill plus top scorers as of 2 August 2015. The best scorers determined by players who scored points from spike, block, and serve. The best spikers determined by
SPIKE algorithm computing the weighted spectral reordering of . The SPIKE algorithm can be generalized by not restricting the preconditioner to be strictly banded. In particular, the diagonal block in each partition can be a general matrix and thus handled by a direct general linear system solver rather than a banded solver. This enhances the preconditioner, and hence allows better chance of convergence and reduces the number of iterations. Intel offers an implementation of the SPIKE algorithm under the name "Intel Adaptive Spike-Based Solver" . Tridiagonal solvers have also been developed for the NVIDIA GPU GPU and the Intel Xeon Phi.
