Hello dear all, we would like to raise an issue that has been discussed sometime before: would the community make use of one single MPI-1.2 standards document? We have found this to be worthwhile for our students, but also, to give a single position (page&Line) in the MPI-Standard, in case an error related to MPI-1.2 is reported in Error-checking tools (and not "MPI1, but with clarification in the MPI2-specification on page X"). Being at it, it would be nice to move to an official PDF-document with links to the calls, sections and references (using latex2e and hyperref). As a start, I would like to suggest the following document (changes are marked with macros for \CHANGE, \INTO, \ADD and \DELETE, the latter text being \it} Please, as *many* eyes as possible should check the correctness of the how&where in the attached changes-file and the mpi-report.pdf and send updates. I would volunteer to document and include updates as suggested and do the final cleanup. With best regards, Rainer PS: There are still some open issues with: - Fig4.1, which does not have Boundary Boxes (and is not included in the PDF) - The links (of the index) are off by 9 pages at the moment... -- ---------------------------------------------------------------- Dipl.-Inf.

- 3.1: Integrated MPI_Get_version into Environmental Section, Inquiries.
(changes to appLang.tex and inquiry.tex)
- 3.2.1: MPI_INITIALIZED:
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
Replaced first sentence, added examples
- 3.2.3 Clarification of status after MPI_WAIT and MPI_TEST
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
Added to the section on Inter-Communication.
- 3.2.5 Clarification of MPI_INTERCOMM_MERGE
Added paragraph on errorhandlers to MPI_INTERCOMM_MERGE
- 3.2.6 Clarification of MPI_TYPE_SIZE
Added advice to users
- 3.2.7 Clarification of MPI_REDUCE
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
Added to section 5.7.1, right after definition of delete_fn
- 3.2.9 Clarification of MPI_PROBE and MPI_IPROBE
Replaced text, left out rationale...
