SUMMARY:Ares – Simulating Type Ia Supernovae on Heterogeneous HPC Architec
 tures
DESCRIPTION:Landon Dyken (University of Illinois, Chicago); Alexander Hola
 s (Heidelberg Institute of Theoretical Studies); Mark Ivan Ugalino (Univer
 sity of Maryland); and Md Nageeb Bin Zaman (Louisiana State University)\n\
 nType Ia Supernovae are highly luminous thermonuclear explosions of white 
 dwarfs which serve as standardizable distance markers for investigating th
 e accelerating expansion of our Universe. Most existing supernovae simulat
 ion codes are only designed to run on homogeneous CPU-only systems and do 
 not take advantage of the increasing shift towards heterogeneous architect
 ures in HPC. To address this, we present Ares, the first performance porta
 ble massively-parallel code for simulating thermonuclear burn fronts. By c
 reating multi-physics modules using the Kokkos and Parthenon frameworks, w
 e are able to scale supernovae simulations to distributed HPC clusters ope
 rating on any of CUDA, HIP, SYCL, HPX, OpenMP and serial backends. We eval
 uate our application by conducting weak and strong scaling studies on both
  CPU and GPU clusters, showing the efficiency of our method for a diverse 
 set of targets.\n\nTag: Artificial Intelligence/Machine Learning, Architec
