WebAs the first example of parallel matrix computations, let us consider the algorithm of matrix-vector multiplication, which is based on rowwise block-striped matrix decomposition scheme. If this case, the operation of inner multiplication of a row of the matrix A and the vector b can be chosen as the basic computational subtask. 7.6.1. http://www.hpcc.unn.ru/mskurs/ENG/DOC/pp07.pdf dream studio foxy
