Dear kathryn,
Good catch, here only a few small corrections and additions:
1)
Now, in Fortran if you declare the buffer in a particular way, the compiler produces a descriptor instead of using a pointer, where a descriptor is a pointer plus some description of the buffer.
-->
Now, in Fortran if the MPI library (in the mpi_f08 or mpi module or mpif.h) declares the buffer ....
2)
different linker names for routines in MPI applications.
-->
different linker names for the same MPI operation.
The appropriate mapping of the MPI call is done through
the specifications within the mpi_f08 or mpi module or mpif.h
3)
After "Some routines will be able to be intercepted ...":
- Special macros in mpi.h report to the tools, which linker names are provided
and whether interception through the C interface is available.
Based on these macros, all needed tool wrappers can be generated.
Best regards
Rolf

Hi all,
For anyone who missed the call, I put some notes on the wiki.
Hopefully, I got the Fortran details right. Anyone with more expertise
in Fortran than I have is welcome to correct me!

Hi all,
This is a reminder of our next telecon tomorrow 4/18 at 8:00 AM PDT,
11:00 AM EDT. The Webex information is posted on the wiki:
https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/MPI3Tools
I expect the main topic of discussion will be the issues dealing with
the new Fortran interface in MPI-3 as they relate to tools. Rolf and
Craig will join the call to fill us in on the details.
If there is time, other topics may include:
- MPI_Pcontrol Fortran problem
- Updates to the MQS document
- Possible change in telecon time to accommodate changed schedules
- What is the openMP tools WG doing for DLL loading?
- Status of ticket #357, threading problems in MPI-3
Kathryn
