Agreed, seems like it has a lot of potential.
I remember some time back when GPUs were first being looked at for HPC uses I suggested a client look into them, but they were quickly dismissed due to their floating point limitation (which may have changed).
But DBs don't have huge FP needs. Another place GPUs are making a big difference is video editing, utilizing CUDA or OpenCL.
- alexchamberlain 15y agoI think their floating point performance is improving.
- Impossible 15y agoGPUs have always had amazing floating point performance for single precision floats, that's basically all graphics is. The problem is that double precision support was traditionally non-existent, and has been slow until recently and it is still much slower than single precision float performance.
- maximilian 15y agoDouble precision performance is now just half speed, which is the same as the CPU. Many applications are bandwidth bound, so running in double vs. single doesn't end up with a 2x difference anyway.
