Gizmo

The simulation code GIZMO is a flexible, massively-parallel, multi-method multi-physics code, with a wide range of different physics modules described in the “Feature Set” below. The code is descended from P-GADGET, itself descended from GADGET–2, and is fully compatible with GADGET analysis codes, initial conditions, and snapshots. GIZMO is not an acronym – it refers both to the code’s multi-purpose applications and to its historical relationship to GADGET.

The code is extensively documented. Please read the User Guide before asking questions of me or other users: most questions I get are already answered here.

The code is written in standard ANSI C, and should run on all parallel platforms that support MPI. The portability of the code has been confirmed on a large number of systems ranging from a laptop to >1 million threads on national super-computers.
