mpgrafic binary package in Ubuntu Noble ppc64el

 mpgrafic produces initial conditions files for N-body simulations of
 cosmological large-scale structure formation. It is a free-licensed,
 MPI-parallelised, rewritten version of Ed Bertschinger's grafic-1
 program, producing output files in the grafic format. It includes
 options for an Eisenstein and Hu baryonic wiggles power spectrum, for
 using a low-resolution map for large-scale modes in the spirit of
 grafic-2, and together with constrfield, can be used for generating
 constrained initial conditions. Details are given in Prunet et al
 (2008) http://cdsads.u-strasbg.fr/abs/2008ApJS..178..179P.
