             Summary: [C++] Runtime SSE path for Aggregate Sum kernel of dense
                 Key: ARROW-8996
                 URL: https://issues.apache.org/jira/browse/ARROW-8996
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Frank Du
            Assignee: Frank Du


Thanks to the new kernel framework, now it can override a SIMD kernel version 
at runtime.

 

Below is the things we need implemented for a SSE version of sum kernel to 
dense data:

1. Add SSE intrinsic path for aggregate sum dense.
 2. Add build support to append the compiler flag for SIMD code file.
 3. Register the SSE version at runtime as the CPU feature.
