@0h00000000@ioc.exchange Not familiar with the internals of database engines to the point I could comment. They work best on massively data-parallel problems with predictable, linear memory address ordering. In general the best case scenario is every thread making 32-bit reads and writes to consecutive word addresses, then doing a ton of flops before the next memory access. The further you diverge from this, the further from theoretical peak performance you get.
