Runtimes (upper panel) and increase in speed (lower panel) as the number of nodes increase in the Hadoop system in two different scenarios: FAST5 file containing 32,000 (blue line), 100,000 (red line), 300,000 (green line) and 1 million (dark blue line) sequences. Dotted line in the lower panel represents the ideal speed-up according to the number of nodes used. Speed-ups have been calculated using 3 nodes as the starting point given that the 1 million reads could not be calculated for1 only one node
