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.
