Hi all, First, just a quick reminder that we need to have the MPI_T document in a final draft state by Monday to make the two week deadline for the MPI forum. Hence, if you have any comments that are more than ticket 0 changes, please let me know. Also, if you edit the document directly, please make sure to update your SVN repository, since people are making changes to it (and send me email afterwards). I am traveling Saturday-Tuesday. I would appreciate any comments, especially larger changes, before the weekend. Further, Bronis has been going over the document and making comments. One in particular I wanted to pass along and put up for discussion. This is regarding the MPI_T_Init_thread behavior, which we discussed before on one of our TelCons. At that time, we decided to add the following advice to users (p.39): \begin{users} The MPI specification does not require all MPI processes to exist before the call to MPI_INIT. If the MPI tool information interface is used before MPI_INIT has been called, MPI_T_INIT_THREAD must be called on each process that exists. Processes created by the MPI implementation during MPI_INIT inherit the status of MPI tool information interface (whether it is initialized or not as well as all active handles) from the process from which they are created. \end{users} Here is Bronis's comment: The advice to users on page 39 is not just advice to users. The problem is that I do not see anywhere that requires inheritance of the tool information interface state. You only mention it in this advice to users, which is non-normative. You need a normative statement that it is inherited. I know we wanted to be careful when we wrote that part, but I kind of agree with Bronis, that this should be stronger. Would it be OK to just drop the "advice" environment, i.e., make the text that is now an advice to a regular part of the document? Thanks!
