This is a follow-up to #14990 as @ofek does not have sufficient time to actively pursue this track now that he is no longer embedded. Most of the code is his, I have just closed some of the outstanding issues with it.

I will be following up on this in a separate PR to flesh out the integration testing. Consider that part of this code base a work in progress.

Regression Test Results

Run ID: de87efa1-824a-4f50-b22b-320481f6a55f
Baseline: b56193e
Comparison: a38d183
Total vector CPUs: 7

Explanation

A regression test is an integrated performance test for vector in a repeatable rig, with varying configuration for vector. What follows is a statistical summary of a brief vector run for each configuration across SHAs given above. The goal of these tests are to determine, quickly, if vector performance is changed and to what degree by a pull request. Where appropriate units are scaled per-core.

The table below, if present, lists those experiments that have experienced a statistically significant change in their bytes_written_per_cpu_second performance between baseline and comparision SHAs, with 90.0% confidence OR have been detected as newly erratic. Negative values mean that baseline is faster, positive comparison. Results that do not exhibit more than a ±5% change in mean bytes_written_per_cpu_second are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting changes are observed.

Changes in bytes_written_per_cpu_second with confidence ≥ 90.00% and absolute Δ mean >= ±5%:

The table below, if present, lists those experiments that have experienced a statistically significant change in their bytes_written_per_cpu_second performance between baseline and comparision SHAs, with 90.0% confidence OR have been detected as newly erratic. Negative values mean that baseline is faster, positive comparison. Results that do not exhibit more than a ±5% change in mean bytes_written_per_cpu_second are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting changes are observed.

Explanation

A regression test is an integrated performance test for vector in a repeatable rig, with varying configuration for vector. What follows is a statistical summary of a brief vector run for each configuration across SHAs given above. The goal of these tests are to determine, quickly, if vector performance is changed and to what degree by a pull request. Where appropriate units are scaled per-core.

The table below, if present, lists those experiments that have experienced a statistically significant change in their bytes_written_per_cpu_second performance between baseline and comparision SHAs, with 90.0% confidence OR have been detected as newly erratic. Negative values mean that baseline is faster, positive comparison. Results that do not exhibit more than a ±5% change in mean bytes_written_per_cpu_second are discarded. An experiment is erratic if its coefficient of variation is greater than 0.1. The abbreviated table will be omitted if no interesting changes are observed.

No interesting changes in bytes_written_per_cpu_second with confidence ≥ 90.00% and absolute Δ mean >= ±5%.
