Cluster Resources Usage. Cluster resources are utilized more efficiently as batch size increases. When the number of exomes increases from (a) 5 exomes to (b) 10 exomes, overall cluster CPU usage (shown as the brown “Total” line) is higher across the entire runtime. Percent CPU usage for each job across the entire 20-node was summed within 5-min “wall time” windows and then scaled by the total number of cores (20 nodes × 32 cores/node = 1920 cores) to quantify the overall system utilization. CPU usage for jobs not fully contained within each 5 min’ window was pro-rated according to how much they overlapped. The contribution of each stage to the entire total (brown line) as a function of time further illustrates the parallelization
