[wlug] It’s Not All CUDA At The High End

This item <https://www.nextplatform.com/2020/03/05/software-evolution-on-ornls-summit-supercomputer/> reports on an interview with Dr Tjerk Straatsma, group lead for scientific computing at ORNL. Seems their supers have made heavy use of NVidia GPUs up to now, but this is set to change: Frontier, the next system for the OLCF, will have AMD CPUs and GPUs. To prepare for this system, software developers may want to make changes to their programming approach, with OpenMP directive-based and HIP native offloading as the most comparable to the OpenACC and CUDA approaches on Summit today. I wonder what happened to OpenCL as the cross-platform architecture for GPU computing?
