| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Graph500 is a benchmark suite for big data analysis which receives attention in these years. The spatial locality of sparse matrices used for Graph500 and the university of Florida sparse matrix collection is investigated. We show the spatial locality of sparse matrices used for Graph500 is very low and there is about 1 or a little more valid data on a cache line for the memory accesses issued by sparse matrix-vector multiplications (SpMV) in average. It is very difficult to solve the problem by just software approach because of the huge size of sparse matrices and the randomness of their accesses to degrade the optimization against their cache awareness. Therefore, hardwired gather functions at cache memory side is promising for taking advantage in the Graph500 lists, which improve the processing speed in an order of magnitude. | |
