Parallelization efficiency. We show the efficiency of the parallelization strategy relative to one process on a whole-genome (1000 Genomes (1000G) in blue) and whole-exome (ExAC in green) dataset. In both cases, we are short of the ideal speedup (gray line) but we observe an approximately sevenfold speedup using 16 processors. Absolute times are provided in Additional file 3: Table S1
