Subject: [OMPI devel] MCA revamp phase 1 in place. SVN quiet time over now
From: Nathan Hjelm (hjelmn_at_[hidden])
Date: 2013-03-27 17:35:29


Phase 1 of the MCA revamp is now in the trunk. Changes:

  - New variable system interface (mca_base_var) replaces mca_base_param.
  - "Shim" layer for mca_base_param implemented on top of mca_base_var. This layer will be removed around June 1, 2013.
  - Support for an "override" MCA variable file (openmpi-mca-param-override.conf). Variables in this file can not be overridden by either the environment or another file.
  - Support for more variable types: bool, unsigned, unsigned long long.
  - Support for enumerated integer variables.
  - Support for the k, m, and g suffix for integers. Ex. 1k = 1024.
  - New framework system. All frameworks have been updated to use the new system.
  - Cleaner ompi_info implementation.
  - Etc. See individual commit messages for more details.

MPI_T_* support will follow in a week or so.
