regina-normal-mpi 4.95-1build2 (i386 binary) in ubuntu vivid

 Regina is a suite of mathematical software for 3-manifold 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 triangulations and normal
 surfaces. Other highlights include angle structures, census enumeration,
 combinatorial recognition of triangulations, and high-level tasks such as
 3-sphere recognition and connected sum decomposition.
 .
 For Regina's standard graphical user interface, install the package
 regina-normal.
