| Summary:
In this paper we introduce the Farpoint simulation, the latest member of the
Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation
family. The domain covers a volume of (1000$h^{-1}$Mpc)$^3$ and evolves close
to two trillion particles, corresponding to a mass resolution of $m_psim
4.6cdot 10^7 h^{-1}$M$_odot$. These specifications enable comprehensive
investigations of the galaxy-halo connection, capturing halos down to small
masses. Further, the large volume resolves scales typical of modern surveys
with good statistical coverage of high mass halos. The simulation was carried
out on the GPU-accelerated system Summit, one of the fastest supercomputers
currently available. We provide specifics about the Farpoint run and present an
initial set of results. The high mass resolution facilitates precise
measurements of important global statistics, such as the halo
concentration-mass relation and the correlation function down to small scales.
Selected subsets of the simulation data products are publicly available via the
HACC Simulation Data Portal.
