AbacusSummit

AbacusSummit is a suite of large, high-accuracy cosmological N-body simulations. These simulations were designed to meet (and exceed!) the Cosmological Simulation Requirements of the Dark Energy Spectroscopic Instrument (DESI) survey. AbacusSummit was run on the Summit supercomputer at the Oak Ridge Leadership Computing Facility under a time allocation from the DOE’s ALCC program.

AbacusSummit was run using the Abacus N-body code. For more information about the code, see Abacus.

The specifications of the ~150 simulations that comprise AbacusSumit are given on the Simulations page.

The cosmologies used by these simulations are specified on the Cosmologies page.

The available data products (halo catalogs, lightcones, etc) are given on the Data Products page.

The abacusutils package can be used to work with AbacusSummit data: https://abacusutils.readthedocs.io. Full examples coming soon!

This documentation and code is hosted in the abacusorg/AbacusSummit GitHub repository. Please file an issue there for questions about AbacusSummit!
