Dear Bill and Jesper and all, thanks for the input so far. On Thursday 5 July 2007 13:27, William Gropp wrote: > Thanks, Rainer.

For items from the > MPI 1.2 part of the MPI-2 document, the text should identify the original Yes, certainly -- these would be marked in the backreferences as well Currently, there's only two trivial proposals for fixes to examples. These would have to be voted for -- I include them here just now. The diff between the old and "new" file is always kept as small as possible.

Possibly, we could have a finalized MPI-1.2 (without further fixes) ready for voting? With best regards, Rainer -- ---------------------------------------------------------------- Dipl.-Inf.

- 3.1: Integrated MPI_Get_version into Environmental Section, Inquiries -- from MPI-2, p. 21
(changes to appLang.tex and inquiry.tex)
- 3.2.1: MPI_INITIALIZED: -- from MPI-2, p. 21
Changed: "is the only function that may be called before" to
"It is one of the few routines that "
- 3.2.2: Include clarification of MPI_FINALIZE -- from MPI-2, p. 22
Replaced first sentence, added examples
- 3.2.3 Clarification of status after MPI_WAIT and MPI_TEST -- from MPI-2, p. 25
Position in standard not completely obvious.
Fits best after the definition of empty statuses in MPI-1, 3.7.3
- 3.2.4 Clarification of MPI_INTERCOMM_CREATE -- from MPI-2, p. 25.
Added to the section on Inter-Communication
- 3.2.5 Clarification of MPI_INTERCOMM_MERGE -- from MPI-2, p. 26.
Added paragraph on errorhandlers to MPI_INTERCOMM_MERGE
- 3.2.6 Clarification of MPI_TYPE_SIZE -- from MPI-2, p. 26
Added advice to users
- 3.2.7 Clarification of MPI_REDUCE -- from MPI-2, p. 26
Required extensive modification:
Is the following text correct?
"Note that it is possible for users to supply different user-defined operations
to \mpifunc{MPI\_REDUCE} in each process"
In MPI-1, p115, line one, it is stated that all processes must provide the smae
op-argument. Possibly in this above text, the user-defined *function* is ment?
- 3.2.8 Clarification of Error Behaviour of Attribute Callback Function -- from MPI-2, p. 26
Added to section 5.7.1, right after definition of delete_fn
- 3.2.9 Clarification of MPI_PROBE and MPI_IPROBE -- from MPI-2, p. 26
Replaced text, left out rationale...
