openmx binary package in Ubuntu Focal s390x

 OpenMX (Open source package for Material eXplorer) is a program package for
 nano-scale material simulations based on density functional theories (DFT),
 norm-conserving pseudopotentials and pseudo-atomic localized
 basis functions. Since the code is designed for the realization of
 large-scale ab initio calculations on parallel computers, it is anticipated
 that OpenMX can be a useful and powerful tool for nano-scale material sciences
 in a wide variety of systems such as biomaterials, carbon nanotubes, magnetic
 materials, and nanoscale conductors.
