"The SYCL*-migrated code of the SynxFlow flood modeling software can run on CPUs, Intel® GPUs, and NVIDIA* GPUs by using the oneAPI plug-ins from Codeplay*. Without any performance optimization yet, for simulations of urban flooding in a large city, the SYCL code can be over 10% faster1 than the original CUDA* code on the same NVIDIA A100 GPUs. The performance is also comparable on Intel® Data Center GPU Max Series 1550, on which the same simulation takes about 40% longer than on NVIDIA A100 GPUs. In terms of scalability, the code achieved almost 90% strong scaling efficiency on both NVIDIA and Intel GPU-based supercomputers."
