At SQream (a GPU-accelerated data warehouse) we use the GPU for many operations, including sorting, aggregating, joining, transformations, projections, etc. We augment the GPU algorithms with external CPU algorithms when the GPU implementations aren't ideal or can't run due to memory constraints. We recently talked about this at a session at CMU's Database Group, if you're interested - https://www.youtube.com/watch?v=bSYFwd50EcU https://www.youtube.com/watch?v=bSYFwd50EcU
