      [refactor] Improve power message format · 63db906e
      Swann Perarnau authored
      This commit changes the message format for the upstream API, to use a
      json-encoded dictionary. While the format is not set in stone at this
      point, the goal is to slowly move into a proper protocol, with
      well-defined fields to the messages, and proper mechanisms to send
      commands and receive notification of their completion.
      
      The only current user of this API is the power management piece, and
      this change breaks the GRM code maintained outside of this repo. We will
      need to reconcile the two implementation once the message protocol gets
      more stable.
      
      Related to #1 and #6.

      [feature] Implement basic CLI · bc1b7fd2
      Swann Perarnau authored
      Only supports setpower for now, and while it should work in theory, the
      current code doesn't have a way to check if the command was received, as
      the daemon never advertise the current limit.
      
      We need to change the protocol at this point.
      
      This also fixes a bug in the daemon code, that was expecting a single
      string as a message, instead of a list of parts, as zmqstream always
      receives.

      [refactor] Use actual sensor info in control loop · 90efdac3
      Swann Perarnau authored
      This patch is the last link between coolr and the daemon. We now create
      a dictionary of machine information inside the sensor manager, and give
      this dictionary back to the daemon. The daemon can then use the real
      data for control.
      
      We still need to receive the target power from somewhere, and that will
      come later.

      Import coolr files into project, link to sensor · 48771c04
      Swann Perarnau authored
      This a partial import of github.com/coolr-hpc/pycoolr from
      master branch, commit id: 67e7aa4b89b67744922b5926cd1459adf650013b
      
      Coolr will provide us the capability to read power, topology and
      msr-based sensors.
      
      This patch links the sensor module with the coolr code as it is, which
      doesn't really work. The core issue is that the current coolr code is
      meant to be stand-alone, and the main functions to both sampling and
      formatting of the data in json, by hand.
      
      We will solve that in the next commit, removing the json-specific code
      from the sample function to create a dict of values instead.

      Move sensor management to separate module · c0b82b60
      Swann Perarnau authored
      Create a `sensor` module that will handle the interaction with coolr and
      return updated machine information regularly.
      
      The code code is as dumb as the previous one, but the structure is
      improved, which should help for the next round of updates with coolr.

      [refactor] Rename clients to applications · 1a8707f2
      Swann Perarnau authored
      Giving the deadlines we have, it's probably a good idea to keep things
      simple and keep the application facing protocol exactly as it is, and
      restrict it to just applications. This way we can keep using the argobots
      tests as valid benchmarks, and at the same start building a decent
      communication protocol on a different socket, with a better interface.
      
      To clarify that, the daemon now use the word application to refer to
      clients connecting on the "legacy" interface.
      
      We'll add a different socket and start building a real protocol in
      future commits.

      [refactor] Python rewrite of the software · 86409f88
      Swann Perarnau authored
      We chose to rewrite the entire thing in python. The language should make
      it easy to interact will all the moving parts of the Argo landscape, and
      easy to prototype various control schemes.
      
      The communication protocol is exactly the same, but implemented with
      ZeroMQ + tornado.
      
      Power readings are not integrated yet, we are targeting using the Coolr
      project for that.
      
      This is a rough draft, all the code is in binary scripts instead of
      the package, and there are no unit tests. Nevertheless, it should be
      a decent starting point for future development.
