------------------------------------
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.
