SUMMARY:Altis-SYCL:  Migrating Altis Benchmarking Suite from CUDA to SYCL 
 for GPUs and FPGAs
DESCRIPTION:Christoph Weckert, Leonardo Solis-Vasquez, Julian Oppermann, a
 nd Andreas Koch (Technical University of Darmstadt) and Oliver Sinnen (Uni
 versity of Auckland)\n\nIn this work, we introduce Altis-SYCL, a benchmark
  suite based on SYCL for GPUs and FPGAs. For developing Altis-SYCL, we lev
 erage the oneAPI heterogeneous programming framework in two consecutive st
 eps: 1) by using the modern Altis GPGPU benchmark suite as baseline and mi
 grating it from CUDA to SYCL, and 2) by exploring several techniques to op
 timize the performance of the resulting SYCL code. Our migration-and-optim
 ization methodology starts targeting GPUs and progressively moves towards 
 FPGAs. In this process, we discuss the differences between device-specific
  strategies as well as detailing the required code refactoring and optimiz
 ation efforts. The performance of Altis-SYCL was evaluated on Stratix 10 a
 nd Agilex FPGAs, and for some applications, their execution runtimes were 
 competitive with those achieved on latest high-end GPUs. The corresponding
  code is released as open source\nunder: https://github.com/esa-tu-darmsta
 dt/altis_sycl.\n\nTag: Architecture and Networks\n\nRegistration Category:
