WebDec 11, 2008 · Recall from Section 4.3 that the CSR (vector) kernel uses one 32-thread warp per matrix row. Since all matrices in our study have fewer than 32 nonzeros per row, the vector kernel is underutilized. Indeed, when the texture cache is enabled, the ratio of GFLOP/s to nonzeros per row only varies between 0.3285 and 0.3367.
