SUMMARY:Accelerating Gravitational N-Body Simulations Using the RISC-V-Bas
 ed Tenstorrent Wormhole
DESCRIPTION:Jenny Lynn Almerol and Elisabetta Boella (E4 Computer Engineer
 ing), Mario Spera (Scuola Internazionale Superiore di Studi Avanzati (SISS
 A)), and Daniele Gregori (E4 Computer Engineering)\n\nAlthough originally 
 developed primarily for artificial intelligence workloads, RISC-V-based ac
 celerators are also emerging as attractive platforms for high-performance 
 scientific computing. In this work, we present our approach to acceleratin
 g an astrophysical N-body code on the RISC-V-based Wormhole n300 card deve
 loped by Tenstorrent. Our results show that this platform can be highly co
 mpetitive for astrophysical simulations employing this class of algorithms
 , delivering more than a 2x speedup and approximately 2x energy savings co
 mpared to a highly optimized CPU implementation of the same code.\n\nRecor
