Jeff Squyres c960d292ec Convert all README files to Markdown
A mindless task for a lazy weekend: convert all the README and
README.txt files to Markdown.  Paired with the slow conversion of all
of our man pages to Markdown, this gives a uniform language to the
Open MPI docs.

This commit moved a bunch of copyright headers out of the top-level
README.txt file, so I updated the relevant copyright header years in
the top-level LICENSE file to match what was removed from README.txt.

Additionally, this commit did (very) little to update the actual
content of the README files.  A very small number of updates were made
for topics that I found blatently obvious while Markdown-izing the
content, but in general, I did not update content during this commit.
For example, there's still quite a bit of text about ORTE that was not
meaningfully updated.

Description

This extension provides a single new function, OMPI_Affinity_str(), that takes a format value and then provides 3 prettyprint strings as output:

  • fmt_type: is an enum that tells OMPI_Affinity_str() whether to use a resource description string or layout string format for ompi_bound and currently_bound output strings.
  • ompi_bound: describes what sockets/cores Open MPI bound this process to (or indicates that Open MPI did not bind this process).
  • currently_bound: describes what sockets/cores this process is currently bound to (or indicates that it is unbound).
  • exists: describes what processors are available in the current host.

See OMPI_Affinity_str(3) for more details.
