Besides that, there were Does 'finally put it to rest' mean, no more discussion is needed, and Fortran binding will be made, or does it mean we will not have any Fortran bindings?

Sorry, this was my fault - I was on travel last week at IPDPS and on vacation after the MPI forum the week before, so I haven't had a chance to send anything out. > > Last thing I heard/read was Jeff stating that MPIT didn't pass the > reading (yet it still made the list for MPI 3.0). > > What were the main points of critique? Kathryn already provided a good summary - here are some comments from my notes: We had a discussion (again) on whether to support Fortran and we (I think) finally put this to rest. Besides that, there were several smaller discussion points, incl. a (IMHO) good proposal to get rid of the attributes without loosing functionality or extensibility.

My suggestion is that I take a first crack at cleaning up the document and that we meet again once this is done and people had a bit to review the changes. Looking at the forum schedule, we need to have the draft for the reading on 7/4. To make this a final version that has hopes for passing the reading, we decided during the meeting that we need a complete draft two weeks before that, i.e., on 6/20 for people to review and comment. Ill try my best to have a first version out 1-2 weeks before that and that would be the time I would suggest to have another call on MPI-T - probably on 6/13. If there are other issues that the tools WG should discuss in the meantime, please let me know and we can schedule those independently. > Is anyone at ICS/WHIST next week? Yes, I will be around.

Hi Marc-Andre, I took some notes during the MPIT reading. Here's some highlights (feel free to add or correct as needed!): There was discussion of whether we need Fortran bindings after all. The primary argument was now that we allow for setting of control variables, programmers may want to do this from their code, which may be in Fortran. - We need to remember all the issues we discussed and dismissed because we had initially decided not to have Fortran bindings. - Waiting until MPI 3.1 to add the bindings might be dangerous because we might miss something if we don't go through it now. - Should have Fortran expert(s) go through it. Ralf didn't see any problems with adding Fortran bindings. - There are questions about how to support Fortran 08. On Page 44, line 6, obj_handle must be a memory address. This needs to be worded better and we need to define what it means. Does the user always need to create a temporary copy to hold the value of the variable since some variables might be a # define , e.g. MPI_COMM_WORLD? Because we changed MPIT types to be MPI types, we need to go through and double check that they will all be available before MPI_Init.

Hi all, it got awfully quiet on the list. Did I miss anything? Last thing I heard/read was Jeff stating that MPIT didn't pass the reading (yet it still made the list for MPI 3.0). What were the main points of critique? When is the next TelCon? Is anyone at ICS/WHIST next week?
