Table 4:

Run statistics for 34-GB BCF file as a function of number of cores

Cores	Memory usage (GB)	Wall clock time (h)	CPU time (h)
1	45	85.59	87.14
2	46.9	41.38	81.39
4	49.3	23.36	89.03
8	54.2	11.88	88.69
16	63.5	6.30	89.73
32	83.2	3.39	87.81

Presented are the memory requirement, wall clock time (actual runtime), and CPU time; see also Fig. 5.
