Aggregate statistics for the 600-way alignment

Alignment No. of genomes Total bases Instance-hours Core-hours Common ancestor size
Zoonomia 242 669 billion 68,166 1.9 million 1.73 Gb
B10K 363 400 billion 5,302 0.2 million 1.13 Gb
Combined 605 1.07 trillion 73,692 2.1 million 181 Mb

The increase in computational work for the mammal alignment compared with the bird alignment is largely caused by the increase in the pairwise alignment phase runtime because it scales quadratically with the size of the genomes being aligned.
