by Martin Schulz 15 Mar '11

15 Mar '11

Hi all, (just in case you are not following the main MPI list) I have updated the MPI_T draft and uploaded it (after some late evening sanity checks by Kathryn - thanks!) to the tools Wiki and ticket #266. It is also checked into SVN. Enjoy the colorful document!

[Mpi3-tools] Last minute reminder: TelCon Monday 3/14, 8am PDT, 11am EDT, 4pm (!) MEZ
by Martin Schulz 14 Mar '11

14 Mar '11

Hi all, As discussed last week, we will have our next MPI-3 tools TelCon on 3/14 at 8am PDT, 11am EDT - note that the time difference to Europe is at the moment only 8 hours and hence the TelCon starts at 4pm MEZ. Jeff has again created a Webex session: https://cisco.webex.com/ciscosales/j.php?ED=160773797&UID=0&PW=NYTRhNTI1ZDE… Password tools I have created a new draft of the tools chapter and add it to the Wiki - changes are mostly cosmetic or reflect the discussion during last TelCons. Currently, we have three points outstanding, which I would like to discuss tomorrow: - How to deal with threading? - Do we need to be aware of the thread level? - What are the implications for performance measurements? - Naming - how do we call the interface and all routines - The forum last time suggested to keep MPIT in the MPI namespace, but we need a prefix. Options: - MPI_T_ - MPI_II_ - MPI_Tools_ - MPI_Vars_ - others? - Should we include strings as MPIT types? - If so, how do we need to adjust the interface to report the string lengths? It would be great if we could come to a conclusion for all of those, so I can create a final draft in time for the two week deadline for the formal reading at the next forum. Thanks!

[Mpi3-tools] Next MPI-3 Tool TelCon on 3/14/11 (shifted by a week)
by Martin Schulz 02 Mar '11

02 Mar '11

Hi all, During the last TelCon we discussed some of the open issues that the MPI forum brought up last time during the MPIT presentation. The notes of this discussion are on the Wiki. The one remaining issue that we didn't get to is thread support and I would like to pick this up during the next call. Originally, the next call was scheduled for 3/7, but I won't be able to make this call (and I assume several other people are in the same situation due to the Exascale meeting in San Diego). Therefore I am proposing to hold the call a week later on 3/14 at the usual time (8am PT), since this still gives us a two week window before the next forum meeting. I hope this works for everyone. Jeff - could you please set this up on Webex again? Thanks, Martin PS: For folks in Europe - I think we are off by an hour that week and 8am PT should translate to 4pm. ________________________________________________________________________ Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulzm CASC @ Lawrence Livermore National Laboratory, Livermore, USA
