regina-normal-mpi binary package in Ubuntu Focal arm64

 Regina is a software package for low-dimensional topologists. This package
 contains the components of Regina designed to run large parallel computations
 on a high-performance cluster using MPI.
 .
 These components are built against the default implementation of MPI,
 and must be run under the default MPI runtime environment (as found
 in the package mpi-default-bin).
 .
 Regina focuses on the study of 3-manifold and 4-manifold triangulations,
 normal surfaces, and angle structures. For Regina's standard graphical
 user interface, and for more information about what Regina can do, see
 the package regina-normal.
