CLEF-SSH simulation runs
The main simulation generated by the CLEF-SSH collaboration is the
CLEF hydrodynamics run, which features a flat Omega_m=0.3 cosmology and
about 158 million particles (2x(428)^3) of gas (baryons) and dark
matter inside a comoving volume of (200 Mpc/h)^3. This simulation was
run at the French national parallel
computing centre of CINES, and consumed about 66000 cpu hours on
128 (SGI R14k) processors. This corresponds to a total wall-clock time
of about one month.
The CLEF hydrodynamics run is presently one of the largest large scale structure simulations including models that account for the effects of radiative cooling and energy feedback in the formation history of Galaxy Clusters. It was run using a modified version of the parallel code package Gadget II (Springel, Yoshida & White, 2001), with an energy feedback model by (Scott Kay, 2004).
