Hi Rolf, Thanks for the corrections and additions. I updated the wiki accordingly. Kathryn On Apr 18, 2013, at 12:31 PM, Rolf Rabenseifner <[email protected]> wrote:

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

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
