Hubert, We have added a solution #3 to the ticket based on discussion in the working group today. That's our current proposal. Could you take a look and see if that will be Fortran compatible? Thanks, ~Jim. On 3/12/13 2:28 PM, Hubert Ritzdorf wrote:

Hi,

concerning Ticket 349. (*) In Fortran, the displacement for dynamic windows may be signed since MPI_BOTTOM of Fortran is not (void *) NULL.. (*) Fortran doesn't have unsigned integers, thus you cannot use a Fortran version of MPI_Disp for arithmetics (such as disp++). (*) MPI Displacements in general may be signed. They might be relative to any address.

Therefore, I can't see that the Proposed Solution 2 solves the problem.

Hubert

Hi All,

I would like to propose the following two tickets for discussion in today's WG meeting:

https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/349 https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/344

#349 is a bugfix that definitely needs to be addressed. #344 is an "elegance of the interface" ticket where I would like to poll the WG to determine the level of support and determine if this should be pursued.

I unfortunately need to duck out at 4pm today, so if possible, I propose that we discuss these at the beginning of the meeting.

Thanks! ~Jim. _______________________________________________ mpi3-rma mailing list [email protected] http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi3-rma
