.SH NAME
mpgrafic \- MPI version of N-body initial conditions grafic package
.SH SYNOPSIS
.B mpgrafic
[\fI\,OPTION\/\fR...] [[\fI\,<\/\fR] \fI\,INPUT_FILE\/\fR] [\fI\,> OUTPUT_FILE\/\fR]
.SH 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.
