Hi Martin, A few things... * I should probably know this, but I probably misplaced the information. How do edit the Wiki page? I tried logging in with my MPI3 Tools password, but it failed. * I think the current MPIR description on the Wiki needs a lot more detail. I think it needs to include a "C" language description that shows the declarations of the structure types, variables, and functions. It's missing type and variable declarations. At the next higher level of detail, it needs to elaborate on the semantics of each of the variables and functions, both from the debugger's and MPI perspective; it currently very thin. At the highest level of detail, it should talk about the different "modes" of useing the interface. For example, the "rank 0 process launches" model used by MPICH 1, vs. the "separate mpirun starter process launches" model used by most other MPI implementations. Also, there are special conventions and used on various MPI implementations. For example, Blue Gene (and now Open MPI) support the notion of co-spawning tool daemons, and several implementations support the notion of partial (scalable subset) attach. * On Monday, I think we need to figure out who's going to be the principle author of the document and who is going to edit/maintain the document.

[Mpi3-tools] Next TelCon 1/12 8am PT, 11am ET, 5pm MEZ

Hi all, Just as a reminder: we have our next MPI Tools WG TelCon on Monday 1/12 at the usual time at 8am PT, 11am ET, 5pm MEZ. Here is the dial-in information: > Toll Free Dial In Number for Offsite Participants: 866-914-3976 > International Access/Caller Paid Dial In Number: 925-424-8105 > Dial In Number for LLNL Onsite Participants: 4-8105 > > Access Security Code: 860609 # Unfortunately, I won't be able to be there for the whole TelCon since I will try to call-in from on the road. Bronis has agreed to lead the TelCon instead. The main topics will be to continue the discussion of the current state of the MPIR interface as well as a presentation by Chris on the MPIR-2 interface, which includes dynamic process support. Please also take a look at the current MPIR description on the Wiki and suggest changes or corrections. The plan is to convert the Wiki in the coming weeks into a standalone document that we can reference in the MPI 2.2 standard. In particular, we still need to document existing, platform specific extensions to MPIR. If you are aware of such an extension, please add it to the Wiki page. Thanks, Martin _______________________________________________________________________ Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulz6 CASC @ Lawrence Livermore National Laboratory, Livermore, USA

No, we decided to move the TelCon by a week to 1/12 to give everyone a bit more time after getting back from the holidays.

[Mpi3-tools] Meeting notes 12/22
by Martin Schulz 22 Dec '08

22 Dec '08

Hi all, The meeting notes for today's (short) meeting are available on the WiKi. The main topic was an update on the MPIR discussion we had during the meeting. In general, we noticed that we need more input from other parties (tool and MPI developers) to ensure that we are capturing all details. If you have contact to people that have an interest/knowledge in this issue, but are not participating already (e.g., other development groups in your organization), please approach them and ask them for feedback. It would be great if we could wrap up this MPIR-1 discussion as soon as possible. The next TelCon dates are: 1/12/09 - (hopefully final) discussion on the MPIR-1 interface with all comments included plus a quick overview over MPIR-2 ideas by Chris Gottbrath 2/2/09 - MPI state and information query interfaces Happy Holidays!

Martin, I can be on the call today but I'm not prepared to answer technical questions from TotalView Tech's perspective about the interface. What I can do is collect questions and have responses for the next meeting.

Have we shifted phase, so that we meet every two weeks starting on 1/12? I assume so.
