SUMMARY:Scalable Alternative Route Computation with ACE: A C++17 Library f
 or HPC Traffic Simulations
DESCRIPTION:Paulo Silva, Pavlína Smolková, Kateřina Slaninová, Jan Martino
 vič, João Barbosa, and Matej Špeťko (IT4Innovations, VSB - Technical Unive
 rsity of Ostrava) and Emanuele Vitali (CSC - IT Center for Science)\n\nWe 
 present ACE (Asynchronous Communication and Execution), a C++17 library fo
 r scalable asynchronous task execution on high performance computing (HPC)
  systems. Integrated into a distributed traffic simulation workflow, ACE a
 ccelerates the computation of alternative routes, a key performance bottle
 neck in large-scale simulations. Unlike the previous Rust-based Evkit appr
 oach, ACE eliminates the multi-minute worker-spawning overhead and manages
  task granularity dynamically. Using scenarios for Prague and the Central 
 Bohemia region, with datasets of up to 25 million routes, ACE achieved up 
 to a 15x speed-up on city-scale workloads with shorter routes and a 1.45x 
 improvement on larger regional workloads. These results highlight ACE’s ab
 ility to adapt to workload characteristics and improve both efficiency and
  scalability in HPC-based route computation.\n\nTag: Research & ACM SRC Po
