The ratio of the F _Hadoop/F _HPC as a function of the reciprocal dataset size in Gb. The pipelines were run on the Hadoop I and II clusters, as well as a 16 core HPC node. The analytical curve f(x)=(a ₁ x+b ₁)/(a ₂ x+b ₂) was used to fit the data for the stretches of linear scaling of calculation time on the HPC platform. The outliers are marked with crossed symbols.
