Fig. 12From: Root Digger: a root placement program for phylogenetic treesPlot depicting parallel efficiency, which is log nodes vs log speedup. Trials were run on 1, 2, 4, 8, 16, and 32 nodes with 16 threads per node using DS7 in exhaustive mode with early stopping turned off. The parallel efficiency ranges from 0.94 on 2 nodes to 0.50 on 32 nodesBack to article page
