What Hacker News says
3 sourcesI was about to comment that Gluten is only targeting CPU vectorization, but then I found this (very cool!): https://github.com/apache/incubator-gluten/issues/9098
I'm not very familiar with Gluten, but I'll still comment on the CPU side though, assuming that one of Gluten's goals is to use the full vector processing (SIMD) potential of the CPU. In that case, we'd still be memory(-bandwidth)-bound, not to mention the significantly lower FLOPs of the CPU itself. If we vectorize Spark (or any MPP) for efficient compute, perhaps we should run it on hardware optimized for vectorized, super-parallel, high-throughput compute.
Also, there's nothing which says we can't use Gluten to have even more CPU+GPU utilization!
In Launch HN: ParaQuery (YC X25) – GPU Accelerated Spark/SQLI've been keeping an eye on these kinds of Spark accelerator libraries for a while now.
How does it compare to Blaze[1] and Gluten[2]?
I'm interested in running some benchmarks soon against all three for my project to see how they all go.
