 Cluster Telemetry allows you to run [telemetry](https://www.chromium.org/developers/telemetry)'s benchmarks, lua scripts and other tasks using multiple repository patches through Alexa's [top 1 million](http://s3.amazonaws.com/alexa-static/top-1m.csv.zip) web pages.
 Developers can use the framework to measure the performance of their patch against the top subset of the internet on both Desktop and Android.
 
-SKP files are a binary format for the draw commands Chromium sends to Skia for rasterization. The goal of the project started off with wanting to collect a large repository of 10k SKP files. This repository, after incremental changes in approaches, has since grown to ~900k and now supports running all telemetry benchmarks. The top level feature request of this project was [skia:1268](https://code.google.com/p/skia/issues/detail?id=1268).

-A web application has been created on App Engine that automates the process of capturing new archives and running telemetry benchmarks at a click of a button; results are emailed to the requester and the web application contains complete history of runs with links to results. You can run telemetry benchmarks at http://ct.skia.org.

 2. Each task is exposed by the web application in JSON. The CT master polls the web application and picks up new tasks.

-Cluster Telemetry is primarily written in Go with a few python scripts. The framework lives in [master/ct](https://skia.googlesource.com/buildbot/+/master/ct) and the appengine code lives in [master/appengine_scripts](https://skia.googlesource.com/buildbot/+/master/appengine_scripts/skia-tree-status).
