[Mpi3-ft] Asynchronous Process Management Interface Proposal
by Josh Hursey 10 Mar '08

10 Mar '08

I just posed a first draft of an Asynchronous interface to the MPI_Comm_spawn operations for process management. The wiki page is here: http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Async-proc-mgmt This is a rough draft at the moment, and I know we have not talked about this on the teleconference calls yet. I wanted to post something so we can start talking about it at a high level before nailing down too many specifics. And to see if there is anyone interested in helping me with this proposal. Let me know what you think. Cheers, Josh

Re: [Mpi3-ft] Recoverability of MPI State Proposal Discussion
by Richard Graham 06 Mar '08

After thinking about this a bit, I decided to take Josh¹s suggestion one more step. The proposal attached to the UTK paper is a good starting point for this whole discussion, so I obtained the permission of the primary authors to use this as a starting point. I will upload this to the web site later today (I hope). While this does not cover items such as dynamic communicators, and even the original authors would do things differently, it is a very good starting point.

I am no the hook to produce a first draft of a document for this. I am planning to do this later in the week, after I finish the 2.1 document reviews I need to do.

[Mpi3-ft] Recoverability of MPI State Proposal Discussion
by Josh Hursey 03 Mar '08

03 Mar '08

I'd like to start the discussion on the proposal for "defining communicator state with process loss", or recoverability of MPI state in the presence of process loss. To start the discussion I am suggesting that folks have a look at the following paper since I think it relates to quite a number of related topics: Fagg, G., et. al. "Extending the MPI Specification for Process Fault Tolerance on High Performance Computing Systems" http://icl.cs.utk.edu/projectsfiles/ftmpi/pubs/isc2004-FT-MPI.pdf ---- Josh Hursey Graduate Student, Indiana University

To add a page to the wiki: - click on the "Edit this page" button at the bottom of the page on which you want to add the link to the page. So typically the mail FaultToleranceWikiPage. - Whereever you want the link to appear just add the text: [wiki:"Transactional-Msg" Transactional Messages] Just after the "wiki:" this will be the page title to show up in the url. After that is the link text to show up on the webpage as the link. - Save this page with the "submit changes" button. You may want to Preview the page before submitting just to make sure the page will appear as you wanted it to. - When you return to the page you added the link to, just follow your new link. The wiki will have automatically created a stub page for you. - To edit the stub page just click on the "edit this page" button at the bottom of that new page. > >> I suggest that we remove the two .txt files from the wiki head so we >> do not become confused as to which document we are talking about. > Sounds good to me. Where's the button for removing the files? I was wondering the same thing. When you click on the attachment it will take you to an HTML page with the attachment. At the bottom of that page there should be a button "Delete attachment" For some reason this button does not appear with the FT Wiki. I wonder if some of the permissions on the wiki are messed up such that you can only delete a page if you are logged in. Just a guess though. -- Josh > > Greg Bronevetsky > Post-Doctoral Researcher > 1028 Building 451 > Lawrence Livermore National Lab > (925) 424-5756 > bronevetsky1(a)llnl.gov > _______________________________________________ > Mpi3-ft mailing list > Mpi3-ft(a)lists.mpi-forum.org > http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi3-ft
