Kevin Lubick e3b013047d Experiment with turning CPUs off during perf
Perf was nice and flat after https://skia-review.googlesource.com/c/skia/+/83240
but there was a 4-5x slowdown on the benchmarks themselves,
indicating that perhaps we were running nanobench on the
LITTLE cores (now on powersave) instead of the big cores we
thought (which were recently scaled down).

This experiment will show us FOR CERTAIN that we are
running on core 0 or 1 which is at .6 max frequency.

We expect to see a speedup from the previous results.

This is leading to turning of CPUs we don't need
to make sure nanobench is running on the ones we expect.

Skia Recipe Modules

This directory contains recipe modules designed to be used by recipes (see infra/bots/recipes). They are all Skia-specific and some are interrelated:

  • builder_name_schema - Helps to derive expected behavior from task (formerly builder) names.
  • core - Use as a starting point for most recipes: runs setup and sync steps.
  • ct - Shared Cluster Telemetry utilities.
  • flavor - Allows the caller to specify a high-level command to run, leaving the platform-specific details to be handled by the specific flavor module.
  • infra - Shared infrastructure-related utilities.
  • run - Utilities for running commands.
  • swarming - Utilities for running Swarming tasks.
  • vars - Common global variables used by Skia recipes/modules.

When you change a recipe module, you generally need to re-train the simulation test:

$ python infra/bots/recipes.py test run --train

Or:

$ cd infra/bots; make train

Each recipe module contains a few files:

  • api.py - This is the meat of the module.
  • __init__.py - Contains a single DEPS variable, indicating the other recipe modules on which this module depends.
  • example.py - Optional, this file contains examples which demonstrate how to use the module and should contain enough tests to achieve 100% coverage for the module. The tests are run using the recipes test command above.
