Fig. 3From: BLAMM: BLAS-based algorithm for finding position weight matrix occurrences in DNA sequences on CPUs and GPUsExample of a pattern matrix P containing 1404 JASPAR PWMs where many columns contain trailing zeros because of differences in length of the corresponding PWMs (panel a). Matrix P subdivided into two (panel b) and four (panel c) tiles. Relative performance gain/loss from tiling for different CPU and GPU architectures (panel d)Back to article page
