AresDB: Uber’s GPU-Powered Open-Source, Real-Time Analytics Engine
Any good resources on where GPU DBs offer significant wins? Especially, but not only, if it wins in cost <i>efficiency</i> for some workload.<p>My naïve impression working at smaller scales is that in a reasonably balanced system, storage is often the bottleneck, and if it can deliver data fast enough the CPU probably won't break a sweat counting or summing or so on. The amount of interest in GPU databases, though, suggests that's not the case for some interesting workloads.
