The Last Journey. I. An Extreme-Scale Simulation on the Mira Supercomputer
Katrin Heitmann, Nicholas Frontiere, Esteban Rangel +10
The Last Journey is a large-volume, gravity-only, cosmological N-body simulation evolving more than 1.24 trillion particles in a periodic box with a side-length of 5.025Gpc. It was…
Generating Synthetic Cosmological Data with GalSampler
Andrew Hearin, Danila Korytov, Eve Kovacs +4
As part of the effort to meet the needs of the Large Synoptic Survey Telescope Dark Energy Science Collaboration (LSST DESC) for accurate, realistically complex mock galaxy catalog…
CosmoDC2: A Synthetic Sky Catalog for Dark Energy Science with LSST
Danila Korytov, Andrew Hearin, Eve Kovacs +27
This paper introduces cosmoDC2, a large synthetic galaxy catalog designed to support precision dark energy science with the Large Synoptic Survey Telescope (LSST). CosmoDC2 is the…
The Outer Rim Simulation: A Path to Many-Core Supercomputers
Katrin Heitmann, Hal Finkel, Adrian Pope +10
We describe the Outer Rim cosmological simulation, one of the largest high-resolution N-body simulations performed to date, aimed at promoting science to be carried out with large-…
HACC Cosmological Simulations: First Data Release
Katrin Heitmann, Thomas D. Uram, Hal Finkel +10
We describe the first major public data release from cosmological simulations carried out with Argonne's HACC code. This initial release covers a range of datasets from large gravi…
