GenomeKey scalability. GenomeKey workflow efficiently scales with increasing number of genomes. a Wall time and (b) cost as a function of number of genomes compared to a linear extrapolation single genome. GenomeKey workflow scales efficiently with increasing number of exomes compared on different GlusterFS configurations. The blue curve represents the 1, 3, 5 and 10 exomes runs performed on a cluster with one GlusterFS brick; the yellow curve represents the scalability on a cluster with four GlusterFS bricks. c Wall time and (d) cost as a function of exome and size for as compared to a linear extrapolation of a single exome
