[Ofa_remotepm] First pass at a presentation slide deck

[Bernard Metzler]

This is great work. Reads very interesting!

Please let me post some general comments, no changes to the current deck.
And please forgive me if those comments are already completely captured by
the deck, and account that to my limited understanding and limited patience
to thoughtfully read through 20+ slides.


   generally: we probably shall not take persistency of memory as a
   challenge in this work group. it is a nice add-on, which we may make
   explicit use of, or ignore. if we ignore it, we still benefit
   implicitly, since that memory is denser and needs less energy (since it
   is persistent). any memory can be made persistent. it is just a question
   of the electrical energy one wants to spend, which is determined by
   technology used to store the bits. so it is a cost factor then only.
   use case: write once, read once scenarios are something we may look into
   as well. we may want to understand if persistency is a feature we can
   benefit from for this type of applications. think about serverless
   approaches (aws lambda, openwhisk, ...) which may provide great
   flexibility to classic big data computing (for what it is currently not
   being used), if intermediate results can be stored in remote PM, or
   local PM, which becomes remote PM for the next function.

Thanks,
Bernard.

Fixed minor spelling error on slide 5.
Corrected slides 15-18 to align cross-references with new deck.

I took the slide deck as it existed as of this evening and:
      -          Moved it onto the OFA template
      -          Began structuring the results in a presentation-style
      format
      -          We only have 20 minutes on Friday, so we obviously can’t
      go through everything that was captured in the notes from the
      meetings.
      -          I kept the original slides and moved them into backup one
      by one as I captured the salient points and combined them with
      others.  Hopefully nothing got lost in the translation.  Also, I may
      not have understood the point being made on one of the original notes
      slides, which is another reason for retaining the originals.
I took a crack at summarizing the key points and observations, and focused
on the three or so use cases that got some significant discussion on Monday
      -          Checkpoint Restart
      -          Streaming Sensor Data
      -          Machine Learning
      -          The Dreamworks Case
I retained Doug’s excellent consolidation.

If this feels like the right way to go, let’s refine and focus these a
little further and call it good.  We don’t have a shared repository, so
there’s no locking mechanism.  Not sure how to deal with that except to
hope for the best.  I suggest if you change the slide deck, re-publish it
to the reflector and include your initials in the file name, e.g.
OFA_RPM_2018_0411_jp.pptx.  That way you’ll at least know if your changes
got incorporated in later versions.

Ps – Is there a volunteer to present this stuff on Friday?
