2015 FIVB Volleyball World League 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 6 July 2015. The best scorers determined by players who scored points from spike, block, and serve. The best spikers determined by players who successfully spike in percentage (%success). The best scorers determined by players who had the most numbers of stuff block divided by numbers of sets which his team played (average stuff block/set). The best scorers determined by players who had the most numbers of ace
SPIKE algorithm SPIKE algorithm The SPIKE algorithm is a hybrid parallel solver for banded linear systems developed by Eric Polizzi and Ahmed Sameh The SPIKE algorithm deals with a linear system , where is a banded formula_1 matrix of bandwidth much less than formula_2, and is an formula_3 matrix containing formula_4 right-hand sides. It is divided into a preprocessing stage and a postprocessing stage. In the preprocessing stage, the linear system is partitioned into a block tridiagonal form Assume, for the time being, that the diagonal blocks ( with ) are nonsingular. Define a block diagonal matrix then is also nonsingular. Left-multiplying
