mummer binary package in Ubuntu Bionic amd64

 MUMmer is a system for rapidly aligning entire genomes, whether
 in complete or draft form. For example, MUMmer 3.0 can find all
 20-basepair or longer exact matches between a pair of 5-megabase genomes
 in 13.7 seconds, using 78 MB of memory, on a 2.4 GHz Linux desktop
 computer. MUMmer can also align incomplete genomes; it handles the 100s
 or 1000s of contigs from a shotgun sequencing project with ease, and
 will align them to another set of contigs or a genome using the NUCmer
 program included with the system. If the species are too divergent for
 DNA sequence alignment to detect similarity, then the PROmer program
 can generate alignments based upon the six-frame translations of both
 input sequences.
