The OpenGadget3 Code for Cosmological Simulations
Klaus Dolag, Geray S. Karademir, Luca Tornatore +28
We present the public release of OpenGadget3 (OG3), a substantially extended and re-organised version of the widely used Gadget-2/3 family of cosmological simulation codes. Since G…
OpenGadget3 GPU solver tests
A. Ragagnin, G. S. Karademir, F. Groth +6
We present an in-depth evaluation of the scalability and accuracy of the GPU porting of the N-body code for hydrodynamic cosmological simulations \og. While technical details of ou…
The Cosmological Simulation Code OpenGadget3 - Implementation of Self-Interacting Dark Matter
Moritz S. Fischer, Marc Wiertel, Cenanda Arido +7
Dark matter (DM) could be subject to non-gravitational self-interactions which is relevant to resolve potential problems of cold DM on small scales. Their impact on astrophysical o…
Performance and energy footprint assessment of FPGAs and GPUs on HPC systems using Astrophysics application
David Goz, Georgios Ieronymakis, Vassilis Papaefstathiou +7
New challenges in Astronomy and Astrophysics (AA) are urging the need for a large number of exceptionally computationally intensive simulations. "Exascale" (and beyond) computation…
Gadget3 on GPUs with OpenACC
Antonio Ragagnin, Klaus Dolag, Mathias Wagner +5
We present preliminary results of a GPU porting of all main Gadget3 modules (gravity computation, SPH density computation, SPH hydrodynamic force, and thermal conduction) using Ope…
INAF Trieste Astronomical Observatory Information Technology Framework
S. Bertocco, D. Goz, L. Tornatore +6
INAF Trieste Astronomical Observatory (OATs) has a long tradition in information technology applied to Astronomical and Astrophysical use cases, particularly for what regards compu…
Exploiting the Space Filling Curve Ordering of Particles in the Neighbour Search of Gadget3
Antonio Ragagnin, Nikola Tchipev, Michael Bader +2
Gadget3 is nowadays one of the most frequently used high performing parallel codes for cosmological hydrodynamical simulations. Recent analyses have shown t\ hat the Neighbour Sear…
A web portal for hydrodynamical, cosmological simulations
Antonio Ragagnin, Klaus Dolag, Veronica Biffi +5
This article describes a data center hosting a web portal for accessing and sharing the output of large, cosmological, hydro-dynamical simulations with a broad scientific community…
