Hi all, Sorry for the delay on the agenda. Hopefully, this will reach you in enough time for planning on joining remotely. We have a lot of items to discuss and I have a feeling we will spend more time on them than we expect and won't get through them all today. We can continue tomorrow if there is a room available. If anyone wants to join remotely tomorrow, let us know and we'll try to set it up. - ticket #384 - ticket #383 - Fortran wrapper generator - PMPI2 - error codes for MPI_T_ENUM functions - atomic vector reads of pvars - can strings in an enum change over time? - multiple device support -- convention for associating pvars with descriptive enum If remote attendees are interested in discussing particular items and have time constraints, let me know and we can try to discuss those when you are on the webex. Also, if anyone notes an item I missed, please let me know so we can add it to the agenda.

But if you can issue a single MPI_T read for N values all at once, you have a much better chance of getting an atomic/consistent set of values. >>>>>>>>>> >>>>>>>>>> -- >>>>>>>>>> Jeff Squyres >>>>>>>>>> jsquyres(a)cisco.com >>>>>>>>>> For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/ >>>>>>>>>> >>>>>>>>>> _______________________________________________ >>>>>>>>>> mpiwg-tools mailing list >>>>>>>>>> mpiwg-tools(a)lists.mpi-forum.org >>>>>>>>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>>>>>>> >>>>>>>>> ________________________________________________________________________ >>>>>>>>> Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulzm >>>>>>>>> CASC @ Lawrence Livermore National Laboratory, Livermore, USA >>>>>>>>> >>>>>>>>> >>>>>>>>> >>>>>>>>> _______________________________________________ >>>>>>>>> mpiwg-tools mailing list >>>>>>>>> mpiwg-tools(a)lists.mpi-forum.org >>>>>>>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>>>>>> >>>>>>>> >>>>>>>> -- >>>>>>>> Jeff Squyres >>>>>>>> jsquyres(a)cisco.com >>>>>>>> For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/ >>>>>>>> >>>>>>>> _______________________________________________ >>>>>>>> mpiwg-tools mailing list >>>>>>>> mpiwg-tools(a)lists.mpi-forum.org >>>>>>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>>>>> >>>>>>> ______________________________________________________________ >>>>>>> Kathryn Mohror, kathryn(a)llnl.gov, http://people.llnl.gov/mohror1 >>>>>>> CASC @ Lawrence Livermore National Laboratory, Livermore, CA, USA >>>>>>> >>>>>>> >>>>>>> >>>>>>> >>>>>>> _______________________________________________ >>>>>>> mpiwg-tools mailing list >>>>>>> mpiwg-tools(a)lists.mpi-forum.org >>>>>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>>>> >>>>>> >>>>>> -- >>>>>> Jeff Squyres >>>>>> jsquyres(a)cisco.com >>>>>> For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/ >>>>>> >>>>>> _______________________________________________ >>>>>> mpiwg-tools mailing list >>>>>> mpiwg-tools(a)lists.mpi-forum.org >>>>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>>> >>>>> ______________________________________________________________ >>>>> Kathryn Mohror, kathryn(a)llnl.gov, http://people.llnl.gov/mohror1 >>>>> CASC @ Lawrence Livermore National Laboratory, Livermore, CA, USA >>>>> >>>>> >>>>> >>>>> >>>>> _______________________________________________ >>>>> mpiwg-tools mailing list >>>>> mpiwg-tools(a)lists.mpi-forum.org >>>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>> >>>> ________________________________________________________________________ >>>> Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulzm >>>> CASC @ Lawrence Livermore National Laboratory, Livermore, USA >>>> >>>> >>>> >>>> _______________________________________________ >>>> mpiwg-tools mailing list >>>> mpiwg-tools(a)lists.mpi-forum.org >>>> http://lists.mpi-forum.org/mailman/listinfo.cgi/mpiwg-tools >>>> >>> >>> -- >>> Marc-Andre Hermanns >>> German Research School for >>> Simulation Sciences GmbH >>> c/o Laboratory for Parallel Programming >>> 52062 Aachen | Germany >>> >>> Tel +49 241 80 99753 >>> Fax +49 241 80 6 99753 >>> Web www.grs-sim.de >>> >>> Members: Forschungszentrum Jülich GmbH | RWTH Aachen University >>> Registered in the commercial register of the local court of >>> Düren (Amtsgericht Düren) under registration number HRB 5268 >>> Registered office: Jülich >>> Executive board: Prof. Marek Behr, Ph.D | Prof. Dr. Sebastian M.
