I just uploaded the 4th draft version of the RTS proposal to the wiki that reflects the notes from todays teleconf. Change log at bottom. https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/ft/run_through_stabilizati... On the teleconf we decided to meet again on Monday, June 27 at 11:30 am EDT - in addition to meeting on Wednesday, June 29 at the regular time. The document should be ready to ship by the Wednesday meeting. We stopped at section 17.9 on todays teleconf. A couple of issues came up on the teleconf that other might want to comment on: - In Section 17.6.2, we need to cleanup the wording here a bit to make it clear about the possible impact on implementations. In particular, does this require that all MPI operations have a check for initialized in them? and how could that check be used to provide the necessary semantics. - Folks were wondering about what we should say regarding how long MPI_Comm_kill should block considering it is a non-collective operation. I added a sentence to the document, not sure if it is good or not but it is a place to start. Anyone have other suggestions? Thanks, Josh Change Log * 17.5.2: Add forward reference to collective chapter in MPI_Comm_validate_all explanation of collective active. * 17.6: Minor wording cleanup * 17.6.1: Tense correction on 'error classes' * 17.6.2: Loosen up the wording a bit 'should try' and add an advice to implementors regarding critical errors. * 17.6.3: Clarify that this is a local operation (non-collective). Also clarify 'process group' * 17.6.3: If the MPI_Comm_kill operation cannot provide the necessary semantics then it should return MPI_ERR_UNSUPPORTED_OPERATION. * 17.6.3: Add a first try at some language about how long MPI_Comm_kill will block - must block until locally finished, may block until globally finished. * 17.7.1: 'effect' -> 'affect' * 17.7.1: Slight clarification improvement to the use of MPI_Comm_validate_set_state_null on an inactive persistent request. * 17.7.1: 'effect' -> 'affect' * 17.8: Clarify advice to implementors * 17.8: Highlight 'undefined' for buffers. * 17.8.1: 'therefor' -> 'therefore' * 17.8.2: Re-order the sentence so it reads a bit better * 17.8.3: Add back reference to Validation operations regarding overlapping collectives with validate_all. * 17.8.4: Bcast Example - Add citation for 'recovery blocks' * 17.9.2: Add missing word ("group") to 'Rationale' * 17.9.2: Clarify that MPI_Comm_is_collectively_active is a local operation. * 17.12.1: Add back reference to window validation operations to advice to users. * 17.13: Put the question in an 'e.g.,' parenthetical. * 17.13.1: Add a bit more clarification to Rationale regarding semantics for MPI_File_close. -- Joshua Hursey Postdoctoral Research Associate Oak Ridge National Laboratory http://users.nccs.gov/~jjhursey
