The publication of the spec got delayed as the spec as not ready. There
was one meeting after the IWOMP conference to discuss further details,
but seemingly some more items need to be solved. Bronis de Supinski
wrote on 17 June that he hopes that the OpenMP 3.1 draft will be
available in few weeks. Cf. also Michael Wong's report at
http://www-949.ibm.com/software/rational/cafe/blogs/ccpp-parallel-multicore/2010/06/21/the-view-from-iwomp-2010-trip-report
If you spend 50 bucks/year, you can become cOMPunity member [1] and get
early access to the draft... (Which neither I nor Jakub have.)
For the features planed for 3.1, see the link above - and the relevant
proceedings in LNCS (linked from the conference site).
The OpenMP 3.1 goals were to refine and extend the existing
specification, not break existing code, and to pose a minimal
implementation burden beyond 3.0. Planed are:
- User-defined reduction operators [according to the proceeding paper,
it looks quite powerful and thus requires quite some work to implement -
thus one wonders about the definition of "minimal"]
- Atomics: support capture/write
- Task scheduling: taskyield construct, final clause
