* initial ACER commit * Code cleanup + several fixes * Q-retrace bug fix + small clean-ups * added documentation for acer * ACER benchmarks * update benchmarks table * Add nightly running of golden and trace tests. (#202) Resolves #200 * comment out nightly trace tests until values reset. * remove redundant observe ignore (#168) * ensure nightly test env containers exist. (#205) Also bump integration test timeout * wxPython removal (#207) Replacing wxPython with Python's Tkinter. Also removing the option to choose multiple files as it is unused and causes errors, and fixing the load file/directory spinner. * Create CONTRIBUTING.md (#210) * Create CONTRIBUTING.md. Resolves #188 * run nightly golden tests sequentially. (#217) Should reduce resource requirements and potential CPU contention but increases overall execution time. * tests: added new setup configuration + test args (#211) - added utils for future tests and conftest - added test args * new docs build * golden test update

|
|
<p>Coach supports the horizontal scale-out of rollout workers in distributed mode. For more information on the design and
|
|
implementation of distributed Coach, see <a class="reference internal" href="design/horizontal_scaling.html#dist-coach-design"><span class="std std-ref">Distributed Coach - Horizontal Scale-Out</span></a>. In the rest of this section, we will describe how to

get started with distributed Coach.</p>

<h2>Interfaces and Implementations<a class="headerlink" href="#interfaces-and-implementations" title="Permalink to this headline">¶</a></h2>
|
|
<p>Coach uses three interfaces to orchestrate, schedule and manager the resources of workers it spawns in the distributed
|
|
mode. These interfaces are the orchestrator, memory backend and the data store. Refer to <a class="reference internal" href="design/horizontal_scaling.html#dist-coach-design"><span class="std std-ref">Distributed Coach - Horizontal Scale-Out</span></a> for
|
|
more information. The following implementation(s) are available for each interface:</p>
