Subject: [OMPI devel] Preparations for moving the btl's
From: Richard Graham (rlgraham_at_[hidden])
Date: 2008-12-03 09:46:08


Now that 1.3 will be released, we would like to go ahead with the plan to
move the btl¹s out of the MPI layer. Greg Koenig who is doing most of the
work has started a wiki page with details on the plans. Right now details
are sketchy, as Greg is digging through the code, and has only hand written
notes on data structures that need to be moved, include files that are not
needed, etc. The page is at:
  https://svn.open-mpi.org/trac/ompi/wiki/BTLExtraction

The first three steps basically only involve code motion, moving items such
as ompi_list, and renaming them, moving where the code is actually located
in the repository, and the like. For these we do not plan to put out a
formal RFC, but comments are very welcome, and any hands that are willing to
help with this are even more welcome.

The last phase where the btl¹s are made dependent on OPAL, and supporting
libraries such as mpools I expect will be disruptive, and will definitely
require an RFC, and will also be a longer process.

Please send comments,
Rich
