------------------------------------

             Summary: Optimization for SIMD instructions in Hive
                 Key: HIVE-10179
                 URL: https://issues.apache.org/jira/browse/HIVE-10179
             Project: Hive
          Issue Type: Improvement
            Reporter: Chengxiang Li
            Assignee: Chengxiang Li


[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.
