Hi all, as I am quite inexperienced with the implementation and use of debugging interfaces I have been more silent about the MPIR discussion, yet, I wanted to raise some questions. I apologize when the answers might seem obvious. ======= Page 7/8, Par. 1: …after it has set MPIR_debug_state to MPIR_DEBUG_SPAWNED and … Should the variable have an initial state? MPIR_NULL? ======= Page 8, Par. 3: …, and avoid defining MPIR_debug_gate in the MPI processes. What does avoid mean? Is it still ok to do so? If it is ok, why should it be avoided? When it is not ok, why not prohibit it? ======= Page 11, Par. 3 + 6: If MPIR_Breakpoint exists the tool should consider this a starter process … if MPIR_i_am_starter ist not defined …. why are there two variables/symbols that seem to do the same thing? ======= Page 18, Par. 10: …is a symbol of any kind, preferably an int, …. If it can be any kind, why prefer an int? Why not require it to be an int? ======= In general: - Some symbols are evaluated for existence or non-existence, yet others have a state (1 or 0). Why?
