I agree, it's a simple copy/paste error - I think we should put this forward as an errata and see what people say.

Yes, I agree - the handle is invalid in the session referenced in the argument. Therefore MPI_T_ERR_INVALID_SESSION seems reasonable to me.

[Mpi3-tools] Boolean type?
by Kathryn Mohror 25 Jul '13

25 Jul '13

Hi all, I was asked: "Would it be possible to add MPI_C_BOOL as a valid type for the MPI tool interface? I have a number of boolean values I am exposing as MPI_INT right now. They are control variables that can be turned on or off. The underlying storage for these variables is bool." He argues that the tool is not missing information if the MPI implementation provides a enumerator that has two values 0: false, and 1:true. Otherwise the tool has an MPI_INT that for some reason won't accept any value other than 1 or 0. The Open MPI trunk does supply an enumerator. As we discussed today, we want to limit the number of types that a tool has to check for. However, are we losing something by not having this type?

[Mpi3-tools] Bad handle return error code
by Kathryn Mohror 25 Jul '13

25 Jul '13

Hi everybody, I got asked a question from Nathan: What should (MPI_T_pvar_read, _write, _reset, etc) return if bad handle is given? He gave this example of erroneous code: { MPI_T_pvar_session session1, session2; MPI_T_pvar_handle handle; char buffer[256]; int count; MPI_T_pvar_session_create (&session1); MPI_T_pvar_session_create (&session2); MPI_T_pvar_handle_alloc (session1, 0, NULL, &handle, &count); MPI_T_pvar_start (session1, handle); /* erroneus statement. should return MPI_T_ERR_INVALID_SESSION or MPI_T_ERR_INVALID_HANDLE */ MPI_T_pvar_read (session2, handle, buffer); } I argue it should return MPI_T_ERR_INVALID_HANDLE since the session is good, it's just that the handle doesn’t match. Do you all agree? If so, we should specify it since it's ambiguous. I believe this is an errata item.

Hi everybody, I think this is ticket 0, but I am not sure: page 585 line 21 of 3.0 reads: "The following function can be used to query the number of control variables, N." However, that section is talking about categories so it should read: "The following function can be used to query the number of categories, N." What do you all think?
