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)
