  • PTP 4.0 release: Helios Release June 23 is complete and successful.
    • Approx 1700 downloads in about 3 weeks so far
    • this includes about 100 from the ptp repository (as opposed to the Helios repository) - which includes PTP 4.0.1
    • stats are available for PTP core, Photran, and RDT - each separately
      • To see download stats, go to committer portal, under "Eclipse Projects," Tools for all Committers, Download stats
        • Search for /stats/releases/helios/org.eclipse.ptp and /stats/ptp (the latter is the PTP specific update site)
  • SR1 release is 9/24/2010 (last Friday of September)
    • (N.B. info gathered while writing these minutes: RC1+2 is Wed 8/11; RC2+2 is 9/1; RC3+2 is 9/8; RC4+2 is 9/15; the +2's are always on Wednesdays)
  • PTP 4.0.1 is already done; 4.0.2 should be within a week or two; PLDT fix coming from Beth; RDT fix will need a CDT updates (Indexing changes from markus); CDT 7.0.1 will probably be at SR1
  • Chris says RDT server jars can be buil against newer CDT if necessary; but keep everything pointed at old CDT 7.0.0 for now
  • Builds: would like to do builds on Hudson machine @; Greg will ask Vivian
  • Next version of PTP: should it be 4.1 or 5.0? Photran is already at 6.0 - probably 5.0 esp. because of anticipated API breakage
    • Jeff recommends Indigo bump of Photran to 7.0
    • Note that feature versions get bumped but plugin versions can be anything you want
  • In general, the Helios release for PTP went pretty smoothly. We didn't meet all requirements but neither did CDT.
  • RDT (Remote Development Tools) - Chris R
    • Spawner has some bugs reported by customers, only with RSE. wkg on a solution. involves being able to cancel things
  • Resource Managers
    • Al is working on bugs for PBS
  • PTP Core Model
    • at previous scaling meeting, discussed how to make model more scalable
  • PLDT - Beth hopes to fix MPI barrier analysis bug soon (introduced with CDT AST changes in 7.0)
    • haven't looked at remote projects yet but need to for next release
  • ETFw
    • Jay got Fredrick CVS access, Beth looks forward to hearing from him on using ETFw Feedback view for compiler
  • Photran - Jeff Overbey
    • Undergrads and Mariano in Argentina are working on refactorings
    • Infrastructure for control flow analysis etc.
    • Haven't looked at Remote projects yet
  • NCSA Tutorial
  • Jay gave tutorial at NCSA, first remotely to Singapore to a small audience, then to the NCSA virtual school workshop - 3 hours
    • install instructs were given out ahead of time. worked well.
    • students used RDT and RemoteTools. All work was remote (none local; would require compiler etc. to do local)
    • Issue: need to be able to query what's available on the remote machine, from eclipse, save as project metadata.
    • 244 students at 10 sites. Local assistants helped students at each site.
    • Jay pre-built sdm on each remote machine
  • PTP tutorial accepted for SC10 - Sunday November 14, 2010 at SC in New Orleans
