See INSTALL.swift for install instructions.
Usage: swift [OPTION]... PARAMFILE
swift_mpi [OPTION]... PARAMFILE
Valid options are:
-a Pin runners using processor affinity.
-c Run with cosmological time integration.
-C Run with cooling.
-d Dry run. Read the parameter file, allocate memory but does not read
the particles from ICs and exit before the start of time integration.
Allows user to check validy of parameter and IC files as well as memory limits.
-D Always drift all particles even the ones far from active particles. This emulates
Gadget-[23] and GIZMO's default behaviours.
-e Enable floating-point exceptions (debugging mode).
-f {int} Overwrite the CPU frequency (Hz) to be used for time measurements.
-g Run with an external gravitational potential.
-G Run with self-gravity.
-n {int} Execute a fixed number of time steps. When unset use the time_end parameter to stop.
-s Run with hydrodynamics.
-S Run with stars.
-t {int} The number of threads to use on each MPI rank. Defaults to 1 if not specified.
-v [12] Increase the level of verbosity
1: MPI-rank 0 writes
2: All MPI-ranks write
-y {int} Time-step frequency at which task graphs are dumped.
-h Print this help message and exit.
See the file examples/parameter_example.yml for an example of parameter file.

Gravity multi dt This fully implements self-gravity bar the periodic task over MPI. Could you please check that is does not break anything on the hydro side ? If you are interested in running with self-gravity I'd recommend using the updated EAGLE_12 case and run with `-D -G`. My next steps is to work on the formal requirement of using `-D` alongside the `-G`. I also need to finish working out the automated scripts to generate code for the higher-order multipoles but that is orthogonal to the integration of the code into the master. See merge request !324
