[Mpi3-tools] Next telecon tomorrow 4/18

[Rolf Rabenseifner]

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
