Subject: [OMPI devel] RFC 2/2: merge the OPAL SOS development branch into trunk
From: Abhishek Kulkarni (adkulkar_at_[hidden])
Date: 2010-03-29 10:58:24


======================================================================
[RFC 2/2]
======================================================================

WHAT: Merge the OPAL SOS development branch into the OMPI trunk.

WHY: Bring over some of the work done to enhance error reporting
capabilities.

WHERE: opal/util/ and a few changes in the ORTE notifier.

TIMEOUT: April 6, Wednesday, COB.

REFERENCE BRANCHES: http://bitbucket.org/jsquyres/opal-sos-fixed/

======================================================================

BACKGROUND:

The OPAL SOS framework tries to meet the following objectives:

- Reduce the cascading error messages and the amount of code needed to
  print an error message.
- Build and aggregate stacks of encountered errors and associate
  related individual errors with each other.
- Allow registration of custom callbacks to intercept error events.

The SOS system provides an interface to log events of varying
severities. These events are associated with an "encoded" error code
which can be used to refer to stacks of SOS events. When logging
events, they can also be transparently relayed to all the activated
notifier components.

The SOS system is described in detail on this wiki page:
