I was talking with a friend in HPC lately who said that AMD is actually quite competitive in the HPC space these days. For example, Frontier (https://docs.olcf.ornl.gov/systems/frontier_user_guide.html) is an all-AMD installation. Do scientists actually use ROCm in their code or does AMD have another programming framework for their Instinct chips?
APU’s for HPC are going to be a wild ride. Accelerated computing in shared memory. Get CPU-focused folks will actually get access to some high throughput compute accessible on the sort of timescales that we can actually reason about (the GPU is so far away).
