GRAvitational COSmology (GRACOS) code release announcement, for version 1.0.1a9
Alexander Shirokov
This is to announce a recent release of version 1.0.1a9 of parallel load balanced adaptive P3M cosmological N-body code named GRACOS. The code has been under development over years…
Gravitational Softening and Adaptive Mass Resolution
Alexander Shirokov
Pairwise forces between particles in cosmological N-body simulations are generally softened to avoid hard collisions. Physically, this softening corresponds to treating the particl…
The imprints of primordial non-gaussianities on large-scale structure: scale dependent bias and abundance of virialized objects
Neal Dalal, Olivier Doré, Dragan Huterer +1
We study the effect of primordial nongaussianity on large-scale structure, focusing upon the most massive virialized objects. Using analytic arguments and N-body simulations, we ca…
GRACOS: Scalable and Load Balanced P3M Cosmological N-body Code
Alexander Shirokov, Edmund Bertschinger
We present a parallel implementation of the particle-particle/particle-mesh (P3M) algorithm for distributed memory clusters. The GRACOS (GRAvitational COSmology) code uses a hybrid…
