A Memory (red) and speed (blue) metrics of running metaSPAdes (top) and MEGAHIT (bottom) on the Wastewater metagenome dataset. The percentage of PMem of the total memory (DRAM+PMem) is shown on the horizontal axis, while the speed cost in folds is shown on the left vertical axis, whereas the amount of PMem used in GB is shown on the right vertical axis. For each memory configuration, we ran the pipeline twice and showed the average results (speed and PMem amounts). B Comparison of MetaHipMer2, MEGAHIT, and metaSPAdes running on the Wastewater metagenomics dataset. All three assemblers were run using 100% PMem. The total time of the wall clock (in minutes) is shown in blue, and the maximum memory consumption (in GB) is shown in red
