Ferdinand Xu commented on HIVE-10179:
-------------------------------------
To show the performance gain, I think one micro benchmark tool would be useful.
> Optimization for SIMD instructions in Hive
> ------------------------------------------

> Key: HIVE-10179

> Project: Hive
> Issue Type: Improvement

> [SIMD|http://en.wikipedia.org/wiki/SIMD] instuctions could be found in most
> of current CPUs, such as Intel's SSE2, SSE3, SSE4.x, AVX and AVX2, and it
> would help Hive to outperform if we can vectorize the mathematical
> manipulation part of Hive. This umbrella JIRA may contains but not limited to
> the subtasks like:
> # Code schema adaption, current JVM is quite strictly on the code schema
> which could be transformed into SIMD instructions during execution.
> # New implementation of mathematical manipulation part of Hive which designed
> to be optimized for SIMD instructions.
