This is why I don't send out meeting reminders... I cause more confusion than I clear up. It is at 1:00pm eastern 12:00pm central, or in about an hour (depending on the speed of this mail getting to you). It's at the usual time.

notes from MPI_Count discussion

section 2.5.8 ...to overcome this *limitation*. p29:9 MPI_COUNT -> MPI_Count p123:32 Move "The following auxillary..." down. p96:16 We don't *return* the value MPI_UNDEFINED; we assign it to the OUT variable size. p96:16 also dont return size from function p102:44 needs to mention get_elements_x p103:27 missing an "and" 103:35 "returns" is listed twice p125 there was some allergic reactions to the pack_size changes drop change on line 4 keep change at line 7 p144:27 recvtype should be pluaral int recvcounts[] (not *) p155:12-13 t in front of the j p155:38 missing a "dot" (multiply) before the extent --> do we need to fix get_extent / get_true_extent to also return count types? (adam thinks that MPI_Aint is not guaranteed to be large enough -- may be problematic for files) Quincy chimes in later that he thinks Adam is right. p161:45-46 pointer types should be array types p194:4 indent is screwed up p194:15-16 t is in front of the j Follow up with Pavan: he doesn't think that the W collectives traw vote: as it stands - yes: 14 - no: 3 -- dave g, pavan, ...? (adam?) - pavan: hates w collectives - dave: hates w collectives - adam: thinks critical pieces missing (elements) -- and others that might be missing, too - abstain: 6 -- didn't get all of them, but saw: - 2 from OSU (Sayantan and the OSU grad student) - new IBM guy - ...? -- Jeff Squyres jsquyres_at_[hidden] For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/

Attendees - Alexander - Quincy - Jeff - David - Fab - Terry Need to add MPI_COUNT: pg 171_at_39 pg 545_at_27 pg 547_at_12 pg 554_at_7 pg16_at_18 "MPI_OFFSET_KIND" -> "MPI_COUNT_KIND" pg16_at_19 "encode address values" -> "encode values" pg16_at_23 "C int or Fortran INTEGER" -> "C int and Fortran INTEGER" pg33_at_18, missing '_X' pg105_at_36, document that MPI_GET_ELEMENTS overflow returns MPI_UNDEFINED. pg106_at_15, MPI_GET_ELEMENTS_X should have been MPI_GET_COUNT_X but is going away. pg98_at_6, 8, missing '_x' pg98_at_15, talk about overflow, return MPI_UNDEFINED. pg163_at_16, wrong opening quote for "in place" pg194_at_48, missing IGATHERW Drop MPI_Get_count_x, not needed - datatype must match call to recv/read/write, which are ints.
