      [feature] Implement simple RM for containers · 1c4645cc
      Swann Perarnau authored
      This patch refactor the resource management and hwloc code into a
      working, albeit very simple scheduling policy. Indeed, the previous code
      contained strong assumptions about the output of hwloc matching an Argo
      NodeOS configuration used during the previous phase of the project, that
      always contained enough CPUs and Mems to perform exclusive scheduling.
      
      The current version is simpler, but should work on more regular systems.
      The patch also improves code organization so that introducing more
      complex scheduling algorithms will be simpler.
      
      The testing of this code resulted in the discovery of simple bugs in the
      daemon children handling code, which should work now.

      [feature] Pull the Argus code into the NRM · 92290b22
      Swann Perarnau authored
      The Argus (globalos) launcher had prototype code to read a container
      manifest, create a container using Judi's code, and map resources using
      hwloc.
      
      This patch brings that code, almost intact, into the NRM repo. This code
      is quite ugly, and the resource mapping crashes if the kernel
      configuration isn't right. But it's still a good starting point, and we
      should be able to improve things little by little.
      
      One part in particular needs attention: SIGCHLD handling. We should
      think of using ioloop-provided facilities to avoid this mess.
      
      The patch also contains the associated CLI changes.
      
      Note: the messaging format is starting to be difficult to keep in check,
      as there's conversions and field checks all over the code. See #3 for
      a possible solution.
