The unique_id field was not used in Open MPI, as it didn't seems to me that the tv guys are using it. Therefore, instead of using the unique_id field in their interface structure, I use the recv_context in our own version. However, as I said, the interface should never be changed, so Pak was right by rolling back this mpi_interface.h file. I'll commit another change soon, where I get rid of our own internal cid field in favor of the unique_id.
Thanks,
george.

Hi Tim, Tim Mattox wrote:Hmm, why should an external debugger dictate the members of our communicator struct? Does MPICH, etc. have the exact same structure for their comunicators? I doubt it.Yes, only for mqs_communicator which shares between the DLL and TV. Infact, the whole mpi_interface.h should not be touched. Nikolay Piskun ofTotalview Tech confirmed it.If George's r16177 change is correct, mqs_taddr_t unique_id is never used or set in OMPI.Yes, it is not used for now. But George seems to have second thought about using this unique_id instead of our own cid to make things consistent. We'll stay tuned on what he has to do...I'm sure TotalView & DLL already need to adjust what binary interfacethey expect based on which version of OMPI they are interacting with...what is one more struct difference?If it is very important for this struct to not change, please add a commentto the struct explaining why it shouldn't be changed.I will, once I've figured out how to modify my existing comment forr16200. Just to show you the kind of badness you'll see by taking things out from the struct should show you a messed up comm name and comm_size, like this on both Solaris AMD and SPARC. By putting this member back tothe struct, at least it can band aid the problem. _WORLD Comm_size 5571033412557294925 Comm_rank 4 Pending receives : none Unexpected messages : no information available Pending sends : none _SELF Comm_size 5571033412557294925 Comm_rank 1 Pending receives : none Unexpected messages : no information available Pending sends : none _NULL Comm_size 5571033412557294925 Comm_rank 0 Pending receives : none Unexpected messages : no information available Pending sends : noneOn 9/24/07, pak...@osl.iu.edu <pak...@osl.iu.edu> wrote:Author: paklui Date: 2007-09-24 15:02:56 EDT (Mon, 24 Sep 2007) New Revision: 16200 URL: https://svn.open-mpi.org/trac/ompi/changeset/16200 Log:mqs_communicator type should not be changed as it serves as the interfacebetween Totalview and DLL.
