Welcome and Introduction to Day 2 

(presentation recording)

A oneAPI Case Study: easyWave - A Tsunami Simulations Application
with demos ZIB's experiences with Intel oneAPI       
- Porting a tsunami application from CUDA to DPC++
- Running DPC++ code on GPU
- From CUDA to DPC++ back to Nvidia GPUs... and FPGAs
- A oneAPI case study with the tsunami simulation easyWave

Live Demos:  Christgau_playbook.tar.gz
(1) overview on CUDA code,
(2) CUDA code execution
(3) guided transformation with Compatibility Tool,
(4) presentation/analysis of generated DPC++ code,
(5) execution on different architectures (Intel CPU + GPU, Nvidia GPU)
