+Overview
+==========
+
+``automan`` is an open source, Python-based automation framework for numerical
+computing.
+
+It is designed to automate the drudge work of managing many numerical
+simulations. As an automation framework it does the following:
+
+- helps you organize your simulations.
+- helps you orchestrate running simulations and then post-processing the
+  results from these.
+- helps you reuse code for the post processing of your simulation data.
+- execute all your simulations and post-processing with one command.
+- optionally distribute your simulations among other computers on your
+  network.
+
+This greatly facilitates reproducibility. Automan is written in pure Python
+and is easy to install.
+
+This document should help you use automan to improve your productivity. If you
+are interested in a more detailed article about automan see here:
+https://arxiv.org/abs/1712.04786
+
+
+Installation
+-------------
+
+The easiest way to install ``automan`` is with pip_::
+
+   $ pip install automan
+
+If you wish to run the latest version that has not been relesed you may clone
+the git repository::
+
+  $ git clone https://github.com/pypr/automan
+
+  $ cd automan
+
+And then run::
+
+  $ python setup.py develop
+
+.. _pip: https://pip.pypa.io/en/stable/
+
+
+Once this is done, move on to the next section that provides a gentle tutorial
+introduction to using automan.
+
+
+Citing ``automan``

+A tutorial on using ``automan``
+================================
+
+Automan is best suited for numerical computations that take a lot of time to
+run. It is most useful when you have to manage the execution of many of these
+numerical computations. Very often one needs to process the output of these
+simulations to either compare the results and then assemble a variety of plots
+or tables for a report or manuscript.
+
+The numerical simulations can be in the form of any executable code, either in
+the form of a binary or a script. In this tutorial we will assume that the
+programs being executed are in the form of Python scripts.
+
+There are three general recommendations we make for your numerical programs to
+be able to use automan effectively.
+
+1. They should be configurable using command line arguments.
+2. They should generate their output files into a directory specified on the
+   command line.
+3. Any post-processed data should be saved into an easy to load datafile to
+   facilitate comparisons with other simulations.
+
+None of these is strictly mandatory but we strongly recommend doing it this
+way.
+
+A simple example
+-----------------
+
+In this tutorial we take a rather trivial program to execute just to
+illustrate the basic concepts. Our basic program is going to simply calculate
+the square of a number passed to it on the command line. Here is how the code
+looks:
+
+.. literalinclude:: ../../examples/tutorial/square.py
+
+
+You can execute this script like so::
+
+  $ python square.py 2.0
+  2.0 4.0
+
+Yay, it works!
+
+.. note::
+
+    If you want to run these examples, they are included along with the
+    example files in the automan source code. The files should be in
+    ``examples/tutorial`` (`Browse online
+    <https://github.com/pypr/automan/tree/master/examples/tutorial>`_).
+
+This example does not produce any output files and doesn't really take any
+configuration arguments. So we don't really need to do much about this.
+
+Now let us say we want to automate the execution of this script with many
+different arguments, let us say 2 different values for now (we can increase it later).
+
+We can now do this with automan. First create a simple script for this, we
+could call it ``automate1.py`` (this is just a convention, you could call it
+anything you want).  The code is as shown below:
+
+.. literalinclude:: ../../examples/tutorial/automate1.py
+   :linenos:
+
+
+Note the following:
+
+- The ``Squares`` class derives from :py:class:`automan.automation.Problem`.
+  This encapsulates all the simulations where we wish to find the square of
+  some number.
+- The ``get_name`` method returns a subdirectory for all the outputs of this
+  problem.
+- The ``get_commands`` returns a list of tuples of the following form,
+  ``(directory_name, command, job_info)``. In this case we don't pass any job
+  information and we'll get to this later. Notice that the two commands
+  specified are essentially what we'd have typed on the terminal.
+- The ``run`` command does nothing much except create a directory. For now let
+  us leave this alone.
+
+
+Let us execute this to see what it does::
+
+  $ python automate1.py
+
+  Writing config.json
+  4 tasks pending and 0 tasks running
+
+  Running task <automan.automation.CommandTask object at 0x10628d978>...
+  Starting worker on localhost.
+  Job run by localhost
+  Running python square.py 2
+
+  Running task <automan.automation.CommandTask object at 0x10628d9b0>...
+  Job run by localhost
+  Running python square.py 1
+  2 tasks pending and 2 tasks running
+  Running task <automan.automation.SolveProblem object at 0x10628d940>...
+
+  Running task <automan.automation.RunAll object at 0x10628d908>...
+  Finished!
+
+So the script executes and seems to have run the requested computations. Let
+us see the output directories::
+
+  $ tree
+  .
+  ├── automate1.py
+  ├── config.json
+  ├── manuscript
+  │   └── figures
+  │       └── squares
+  ├── outputs
+  │   └── squares
+  │       ├── 1
+  │       │   ├── job_info.json
+  │       │   ├── stderr.txt
+  │       │   └── stdout.txt
+  │       └── 2
+  │           ├── job_info.json
+  │           ├── stderr.txt
+  │           └── stdout.txt
+  └── square.py
+
+  7 directories, 9 files
+
+Let us summarize what just happened:
+
+- The two commands we asked for were executed and the respective outputs of
+  each invocation were placed into ``outputs/squares/1`` and
+  ``outputs/squares/2``. Notice that there are ``stdout.txt, stderr.txt`` and
+  a ``job_info.json`` file here too.
+- A manuscript directory called ``manuscript/figures/squares`` is created.
+- There is also a new ``config.json`` that we can safely ignore for now.
+
+Let us see the contents of the files in the outputs directory::
+
+  $ cat outputs/squares/1/stdout.txt
+  1.0 1.0
+
+  $ cat outputs/squares/1/job_info.json
+  {"start": "Fri Aug 24 01:11:46 2018", "end": "Fri Aug 24 01:11:46 2018", "status": "done", "exitcode": 0, "pid": 20381}
+
+As you can see, the standard output has the output of the command. The
+``job_info.json`` has information about the actual execution of the code. This
+is very useful in general.
+
+Thus automan has executed the code, organized the output directories and
+collected the standard output and information about the execution of the
+tasks.
+
+Now, let us run the automation again::
+
+  $ python automate1.py
+  0 tasks pending and 0 tasks running
+  Finished!
+
+It does not re-run the code as it detects that everything is complete.
+
+Adding some post-processing
+----------------------------
+
+Let us say we want to create a plot that either compares the individual runs
+or assembles the runs into a single plot or collects the data into a single
+file. We can easily do this by adding more code into the ``run`` method of our
+``Squares`` class. Let us also add a couple of more computations.
+
+.. literalinclude:: ../../examples/tutorial/automate2.py
+   :linenos:
+
+Let us examine this code a little carefully:
+
+- In ``get_commands``, we have simply added two more cases.
+
+- In ``run``, we have added some simple code to just iterate over the 4
+  directories we should have and then read the standard output into a list and
+  finally we write that out into an ``output.txt`` file.
+
+- We also moved the ``automator`` object creation and execution so we can
+  import our ``automate2.py`` script if we wish to.
+
+The two new methods you see here are ``self.input_path(...)`` which makes it
+easy to access any paths inside the simulation directories and the
+``self.output_path(...)`` which does the same but inside the output path. Let
+us see what these do, inside the directory containing the ``automate2.py`` if
+you start up a Python interpreter (IPython_ would be much nicer), you can do
+the following::
+
+  >>> import automate2
+  >>> squares = automate2.Squares(
+  ...    simulation_dir='outputs',
+  ...    output_dir='manuscript/figures/'
+  ... )
+
+  >>> squares.input_path('1')
+  'outputs/squares/1'
+
+  >>> squares.input_path('1', 'stdout.txt')
+  'outputs/squares/1/stdout.txt'
+
+  >>> squares.output_path('output.txt')
+  'manuscript/figures/squares/output.txt'
+
+.. _IPython: ://ipython.org/
+
+As you can see, these are just conveniences for finding the input file paths
+and the output file paths.  Now let us run this new script::
+
+  $ python automate2.py
+  0 tasks pending and 0 tasks running
+  Finished!
+
+Whoa! That doesn't seem right? What happens is that since the last time we ran
+the automate script, it created the output, it assumes that there is nothing
+more to do as the final result (the ``manuscript/figures/squares``) was
+successfully created so it does not run anything new.  If you do this::
+
+  $ python automate2.py -h
+
+You'll see an option ``-f`` which basically redoes the post-processing by
+removing any old plots, so let us try that::
+
+  $ python automate2.py -f
+  4 tasks pending and 0 tasks running
+  ...
+  Finished!
+
+Now it actually ran just the new simulations (you can see the commands in the
+output it prints), it will not re-run the already executed cases. Now let us
+see if the output is collected::
+
+  $ cat manuscript/figures/squares/output.txt
+  [['1.0', '1.0'], ['2.0', '4.0'], ['3.0', '9.0'], ['4.0', '16.0']]
+
+So what automan did was to execute the newly added cases and then executed our
+post-processing code in the ``run`` method to produce the output.
+
+Building on this we have a slightly improved script, called ``automate3.py``,
+which makes a plot:
+
+.. literalinclude:: ../../examples/tutorial/automate3.py
+   :linenos:
+
+This version simplifies the command generation by using a list-comprehension,
+so reduces several lines of code. It then makes a matplotlib plot with the
+collected data.  Let us run this::
+
+  $ python automate3.py -f
+  5 tasks pending and 0 tasks running
+  ...
+  Finished!
+
+  $ ls manuscript/figures/squares/
+  squares.pdf
+
+
+As you can see, the old ``output.txt`` is gone and our plot is available.
+
+.. note::
+   This example requires that you have matplotlib_ and NumPy_ installed.
+
+
+.. _NumPy: https://www.numpy.org/
+.. _matplotlib: https://matplotlib.org/
+
+
+If you wanted to change the plotting style in any way, you can do so and
+simply re-run ``python automate3.py -f`` and it will only regenerate the final
+plot without re-executing the actual simulations.
+
+So what if you wish to re-run any of these cases? In this case you will need
+to manually remove the particular simulation (or even all of them). Let us try
+this::
+
+  $ rm -rf outputs/squares/3
+
+  $ python automate3.py -f
+  3 tasks pending and 0 tasks running
+  ...
+  Finished!
+
+It will just run the missing case and re-generate the plots.
+
+While this may not seem like much, we've fully automated our simulation and
+analysis.
+
+
+Doing things a bit better
+----------------------------
+
+The previous section demonstrated the basic ideas so you can get started
+quickly. Our example problem was very simple and only produced command line
+output. Our next example is a simple problem in the same directory called
+``powers.py``. This problem is also simple but supports a few command line
+arguments and is as follows:
+
+.. literalinclude:: ../../examples/tutorial/powers.py
+   :linenos:
+
+Again, the example is very simple, bulk of the code is parsing command line
+arguments. There are three arguments the code can take:
+
+- ``--power power`` specifies the power to be computed.
+- ``--max`` specifies the largest integer in sequence whose power is to be
+  computed
+- ``--output-dir`` is the directory where the output should be generated.
+
+When executed, the script will create a ``results.npz`` file which contains
+the results stored as NumPy_ arrays. This example also requires that
+matplotlib_ and NumPy_ be installed.  Let us run the code::
+
+  $ python powers.py
+
+  $ ls results.npz
+  results.npz
+
+  $ python powers.py --power 3.5
+
+On a Python interpreter we can quickly look at the results::
+
+  $ python
+
+  >>> import numpy as np
+  >>> data = np.load('results.npz')
+  >>> data['x']
+  >>> data['y']
+
+This looks about right, so let us move on to see how we can automate running
+several cases of this script in a better way than what we had before. We will
+continue to automate the previous ``squares.py`` script. This shows you how
+you can use automan incrementally as you add more cases. We only show the
+lines that are changed and do not reproduce the ``Squares`` problem class in
+the listing below.
+
+
+.. literalinclude:: ../../examples/tutorial/automate4.py
+   :lines: 31-
+   :lineno-match:
+
+To see the complete file see `automate4.py
+<https://github.com/pypr/automan/tree/master/examples/tutorial>`_. The key
+points to note in the code are the following:
+
+- As before ``get_name()`` simply returns a convenient name where the outputs
+  will be stored.
+- A new ``setup()`` method is used and this creates an instance attribute
+  called ``self.cases`` which is a list of cases we wish to simulate. Instead
+  of using strings in the ``get_commands`` we simply setup the ``cases`` and
+  no longer need to create a ``get_commands``. We discuss ``Simulation``
+  instances in greater detail below.
+- The ``run()`` method is similar except it uses the ``cases`` attribute and
+  some conveniences of the simulation objects for convenience.
+
+
+The :py:class:`automan.automation.Simulation` instances we create are more
+general purpose and are very handy. A simulation instance's first argument is
+the the output directory and the second is a basic command to execute. It
+takes a third optional argument called ``job_info`` which specifies the number
+of cores and threads to use and we discuss this later. For now let us ignore
+it. In addition any keyword arguments one passes to this are automatically
+converted to command line arguments. Let us try to create one of these on an
+interpreter to see what is going on::
+
+  >>> from automan.api import Simulation
+  >>> s = Simulation(root='some_output/dir/blah',
+  ...                base_command='python powers.py', power=3.5)
+  >>> s.name
+  'blah'
+  >>> s.command
+  'python powers.py --power=3.5'
+  >>> s.params
+  {'power': 3.5}
+
+Notice that the name is simply the basename of the root path. You will see
+that additional keyword argument ``power=3.5`` is converted to a suitable
+command line argument. This is done by the
+``Simulation.get_command_line_args`` method and can be overridden if you wish
+to do something different. The ``Simulation.params`` attribute simply stores
+all the keyword arguments so you could use it later while post-processing.
+
+Now we want that each execution of this command produces output into the
+correct directory. We could either roll this into the ``base_command``
+argument by passing the correct output directory or there is a nicer way to do
+this using the magic ``$output_dir`` argument that is automatically set the
+output directory when the command is executed, for example::
+
+  >>> from automan.api import Simulation
+  >>> s = Simulation(root='some_output/dir/blah',
+  ...                base_command='python powers.py --output-dir $output_dir', power=3.5)
+  >>> s.command
+  'python powers.py --output-dir $output_dir --power=3.5'
+
+Note that the magic variable is not substituted at this point but later when
+the program is about to be executed.
+
+Given these details, the code in the ``run`` method should be fairly
+straightforward to understand. Note that this organization of our code has
+made us maximize reuse of our plotting code. The ``case.params`` attribute is
+convenient when post-prprocessing. One can also filter the cases using the
+``filter_cases`` function that is provided by ``automan``. We discuss this
+later.
+
+The last change to note is that we add the ``Powers`` class to the
+``Automator``'s ``all_problems`` and we are done.Let us now run this::
+
+  $ python automate4.py
+  6 tasks pending and 0 tasks running
+  ...
+  Finished!
+
+This only executes the new cases from the ``Powers`` class and makes the plot
+in ``manuscript/figures/powers/powers.pdf``.
+
+Using :py:class:`automan.automation.Simulation` instances allows us to
+parametrize simulations with the keyword arguments. In addition, it is handy
+while post-processing. We can also subclass the ``Simulation`` instance to
+customize various things or share code.
+
+There are a few more conveniences that automan provides that are useful while
+post-processing and these are discussed below.
+
+
+Filtering and comparing cases
+------------------------------
+
+.. py:currentmodule:: automan.automation
+
+``automan`` provides a couple of handy functions to help filter the different
+cases based on the parameters or the name of the cases. One can also make
+plots for a collection of cases and compare them easily.
+
+- The :py:func:`filter_cases` function takes a sequence of cases
+  and any additional keyword arguments with parameter values and filters out
+  the cases having those parameter values. For example from our previous
+  example in the ``Powers`` class, if we do the following::
+
+   filtered_cases = filter_cases(cases, power=2)
+
+  will return a list with a single case which uses ``power=2``. This is very
+  handy. This function can also be passed a callable which returns ``True``
+  for any acceptable case.  For example::
+
+    filter_cases(cases, lambda x: x.params['power'] % 2)
+
+  will return all the cases with odd powers.
+
+- The :py:func:`filter_by_name` function filters the cases whose
+  names match the list of names passed.  For example::
+
+    filter_by_name(cases, ['1', '4'])
+
+  will return the two simulations whose names are equal to ``'1'`` or ``'4'``.
+
+- The :py:func:`compare_runs` function calls a method or callable
+  with the given cases. This is very handy to make comparison plots.
+
+With this information you should be in a position to automate your
+computational simulations and analysis.
+
+Next we look at setting up additional remote computers on which we can execute
+our computations.
+
+
+Using additional computational resources
+----------------------------------------
+
+Wouldn't it be nice if we could easily run part of the simulations on one or
+more remote computers? ``automan`` makes this possible. Let us see how with
+our last example.
+
+Let us first remove all the generated outputs and files so we can try this::
+
+  $ rm -rf outputs/ manuscript/figures config.json
+
+Running the simulations on a remote machine requires a few things:
+
+- the computer should be running either Mac OS or Linux/Unix.
+- you should have an account on the computer, and be able to ``ssh`` into it
+  without a password (see `article on password-less ssh
+  <http://askubuntu.com/questions/46930/how-can-i-set-up-password-less-ssh-login>`_.
+- the computer should have a working basic Python interpreter.
+
+For more complex dependencies, you need to make sure the remote machine has
+the necessary software.
+
+
+Assuming you have these requirements on a computer accessible on your network
+you can do the following::
+
+  $ python automate4.py -a host_name
+  [...]
+
+Where ``host_name`` is either the computer's name or IP address. This will
+print a lot of output and attempt to setup a virtual environment on the remote
+machine. If it fails, it will print out some instructions for you to fix.
+
+If this succeeds, you can now simply use the automation script just as before
+and it will now run some of the code on the remote machine depending on its
+availability.  For example::
+
+   $ python automate4.py
+   14 tasks pending and 0 tasks running
+
+   Running task <automan.automation.CommandTask object at 0x1141da748>...
+   Starting worker on localhost.
+   Job run by localhost
+   Running python powers.py --output-dir outputs/powers/4 --power=4.0
+
+   Running task <automan.automation.CommandTask object at 0x1141da6d8>...
+   Starting worker on 10.1.10.242.
+   Job run by 10.1.10.242
+   Running python powers.py --output-dir outputs/powers/3 --power=3.0
+   ...
+
+
+Note that you can add new machines at any point. For example you may have
+finished running a few simulations already and are simulating a new problem
+that you wish to distribute, you can add a new machine and fire the automation
+script and it will use it for the new simulations.
+
+When you add a new remote host ``automan`` does the following:
+
+- Creates an ``automan`` directory in the remote machine home directory (you
+  can set a different home using ``python automate4.py -a host --home
+  other_home``.)
+- Inside this directory it copies the current project directory, ``tutorial``
+  in the present case.
+- It then copies over a ``bootstrap.sh`` and ``update.sh`` and runs the
+  ``bootstrap.sh`` script. These scripts are inside a ``.automan/`` directory
+  on your localhost and you may edit these if you need to.
+
+The bootstrap code does the following:
+
+- It creates a virtualenv_ called ``tutorial`` on this computer using the
+  system Python and puts this in ``automan/envs/tutorial``.
+- It then activates this environment, installs ``automan`` and also runs any
+  ``requirements.txt`` if they exist in the tutorial directory.
+
+If for some reason this script fails, you may edit it on the remote host and
+re-run it.
+
+When executing the code, automan copies over the files from the remote host to
+your computer once the simulation is completed and also deletes the output
+files on the remote machine.
+
+If your remote computer shares your file-system via nfs or so, you can specify
+this when you add the host as follows::
+
+  $ python automate4.py -a host_sharing_nfs_files --nfs
+
+In this case, files will not be copied back and forth from the remote host.
+
+
+.. _virtualenv: https://virtualenv.pypa.io/
+
+Now lets say you update files inside your project you can update the remote
+hosts using::
+
+   $ python automate4.py -u
+
+This will update all remote workers and also run the ``update.sh`` script on
+all of them. It will also copy your local modifications to the scripts in
+``.automan``. It will then run any simulations.
+
+Lets say you do not want to use a particular host, you can remove the entry
+for this in the ``config.json`` file.
+
+When ``automan`` distributes tasks to machines, local and remote, it needs
+some information about the task and the remote machines. Recall that when we
+created the ``Simulation`` instances we could pass in a ``job_info`` keyword
+argument. The ``job_info`` is an optional dictionary with the following
+optional keys:
+
+- ``'n_core'``: the number of cores that this simulation requires. This is
+  used for scheduling tasks. For example if you set ``n_core=4`` and have a
+  computer with only 2 cores, automan will not be able to run this job on this
+  machine at all. On the other hand if the task does indeed consume more than
+  one core and you set the value to one, then the scheduler will run the job
+  on a computer with only one core available.
+- ``'n_thread'``: the number of threads to use. This is used to set the
+  environment variable ``OMP_NUM_THREADS`` for OpenMP executions.
+
+
+As an example, here is how one would use this::
+
+  Simulation(root=self.input_path('3.5'),
+             base_command='python powers.py',
+             job_info=dict(n_core=1, n_thread=1),
+             power=3.5
+  )
+
+This job requires only a single core. So when automan tries to execute the job
+on a computer it looks at the load on the computer and if one core is free, it
+will execute the job.
+
+If for some reason you are not happy with how the remote computer is managed
+and wish to customize it, you can feel free to subclass the
+:py:class:`automan.cluster_manager.ClusterManager` class. You may pass this in
+to the :py:class:`automan.automation.Automator` class as the
+``cluster_manager_factory`` and it will use it.
+
+
+
+Using docker
+------------
+
+It should be possible to use automan from within a Docker_ container. This can
+be done either by specifying commands to be run within suitable ``docker run``
+invocations. Alternatively, one can install automan and run scripts within the
+docker container and this will work correctly.
+
+Using docker for remote computers is not fully supported at this time.
+
+.. _Docker: https://www.docker.com/
+
+Learning more
+-------------
+
+If you wish to learn more about automan you may find the following useful:
+
+- Read the draft of the paper on ``automan`` here: https://arxiv.org/abs/1712.04786
+
+- The paper mentions another manuscript which was fully automated using
+  automan, the sources for this are at https://gitlab.com/prabhu/edac_sph/ and
+  this demonstrates a complete real-world example of using automan to automate
+  an entire research paper.
+
+- Olivier Mesnard has created a nice example as part of the review of this
+  paper that can be seen here: https://github.com/mesnardo/automan-example the
+  example also nicely shows how automan can be used from within a docker
+  container for a completely reproducible workflow.
