NAME

       mpgrafic - MPI version of N-body initial conditions grafic package

SYNOPSIS

       mpgrafic [OPTION...] [[<] INPUT_FILE] [> OUTPUT_FILE]

DESCRIPTION

       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.
