> Also, I'm not a GPU programmer but I'm curious, isn't having a uniform split size for all the tables involved in a session be better for GPU bandwidth utilization My starting point was actually a single global default size. I don't see per-table tuning as a GPU-specific concern. It is like with the CPU the ideal split size depends on compression ratios, table size (e.g. dim vs fact in a join). The GPU specific part is that you often want it much bigger relative to the CPU setting. -- This is an automated message from the Apache Git Service.
