Re: [Mpi3-tools] Updates to DLL Discovery API proposal

Forgot to mention -- I updated OMPI's development trunk to follow this new proposal (all that was required was changing to ensure that the global variables were only assigned *after* the argv-style arrays were completely setup): https://svn.open-mpi.org/trac/ompi/changeset/20681 On Mar 2, 2009, at 4:25 PM, Jeff Squyres wrote: > Per the call today, I updated https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/MPI3Tools/dllapi > to remove all references to MPIR_debug_gate, and changed the text > to reflect that the debugger may read the value at any time.

[Mpi3-tools] Updates to DLL Discovery API proposal
by Jeff Squyres 02 Mar '09

02 Mar '09

Per the call today, I updated https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/MPI3Tools/dllapi to remove all references to MPIR_debug_gate, and changed the text to reflect that the debugger may read the value at any time. If the symbol does not exist, then the MPI doesn't support the DLL and the debugger shouldn't bother checking again. If the symbol exists and has a NULL value, the debugger should try again later. If the symbol exists and does not have a NULL value, then the debugger can try the DLLs listed in the array. I will likely not update the MPI handle debugging API proposal until after we get some feedback from the Forum. -- Jeff Squyres Cisco Systems
