Minutes

1. Attendees:
   • Jeff Overbey, John Eblen, Chris Navarro, Dave Wooton, Greg Watson, Jay Alameda, Wyatt Spear, on the call
2. Overall project, releases
   • Next builds, releases:
     • On the release side of things, did have 5.0.7 on April 3, this was for IBM, have a product coming out, wanted a point release to correspond to that – that is the last 5.0 release that is planned at this stage, and have not yet incremented version #s to 5.0.8.  Have tagged repo for 5.0.7, with tags, there is at least one guy who needs this tag.
     • Do you think we’ll need a 5.0.8 release? No plans from Greg, but if someone requests one, no reason to not do it
     • Still bug fixes going into 5.0 branch.  Not doing a lot of work on this branch (Greg), outside of bug fixes, not much activity in this
     • On 6.0/Juno – next milestone is M7, on May 8, this is the last milestone build.  After that, RC builds.
     • Greg is still doing refactoring/API changes, hope to finish way before May 8 – still have some work to do – this is the work that changes significantly how you interact with resource managers.  Want to give people time to take a look at this, give Greg feedbacks, onus is on Greg to get this in as soon as possible, with API freeze on May 8.  Any concerns on this date?
     • Don’t think so (Jeff)
     • Tentatively set the freeze for May 8, next dev call is May 8, we can review this at that point
   • Download Stats
     • Download stats, 53,000 downloads as of yesterday
       When asked for breakdown, 50% are coming from China
     • Lots of activity over there
     • Windows – 25,000, linux, 11,500, mac, is 4,500 – linux is catching up it seems
   • Git Status
     • No git status at this point
   • EclipseCon –
     • A few of us were at eclipsecon week before last, Greg gave presentation on synchronized projects –Chris was this talk, had 30 or so people in the room –
     • Some questions at the end, some interest –
     • Some people in the audience, not targeted at them – but definitely some interest and good comments/feedback on  eclipsecon website
     • This seemed to go well – conference was good, 650 people attended, a little less than normal – whole breadth of the community amazes Greg – the community is alive and well #**Anything from Chris on eclipsecon
     • Thought that the git tutorial was very helpful, to help understand the concepts
     • Covered a lot of material
     • Really enjoyed most of the talks – E4, javafx – interesting retooling – tech lead on this developed swt, this will be successor for swing and java, this looked interesting
     • Greg found out that CDT – next release, will be 8.1, will not be 9.0 as originally thought –this is an FYI.
     • And it sounds like 4.2 – Jeff had concerns about performance of 4.2, did raise this at the CDT summer – consensus was that they were going to go with 4.2 rather than 3.8, not experiencing performance issues
     • Greg noticed some performance issues, but seems to be better than that
     • Jeff will try with a new milestone,
     • Are they using apis exclusive to 4.2 –
     • At this stage, not using any APIs exclusive to 4.2 – not sure if this is the case for juno in the end.  PTP is not using 4.2 APIs.
     • What else – other thing, with CDT – sounds like addressed a lot of performance issues – in particular, the persistent issue that hear about – in using CDT – is indexer problem – primarily that indexer locks the workspace while indexing
     • And if you change a file, in previous versions, reindexed whole project, and with large project, this causes large delays
     • With  juno CDT, have addressed this issue – no longer locks workspace for duration of the indexing – this will hopefully take away one of the major impediments of using CDT
     • Don’t know this will impact on Photran –
     • Photran is independent of this, jeff will look into this to make sure though
     • Does Photran lock the workspace while indexing
     • Don’t recall, it might
     • Jeff has to look at the issue – code was written a long time ago
     • And – went to interesting talk (after Greg’s) – sergey from google, rewritten refactoring framework in CDT, apparently it works properly now
     • There were a lot of issues with more complicated refactorings with CDT, this has been reengineered
     • Would be interesting to see what other’s experience – this will show up in 8.1 –
     • Jeff’s research group had laundry list of refactoring issues in CDT – don’t have a platform for doing decent c/c++ refactoring, hopefully this will address the issue
     • Works with CPP as well
     • Definitely worth taking a look at
     • A lot of work going into multi-core debugging tools
     • Visualizer for looking into multicore systems, contributed by a vendor in this area
     • Similarity to what we are doing with system monitoring, but not much opportunity to integrate these together, they have gone in a different direction, would take a fair amount of work to bring us together
     • But what they have is interesting/useful
     • Anybody else from EclipseCon?
     • Jeff –sure attendance was down a little bit, due to economy etc
     • Did you get a sense that Eclipse is trending any way – are there any serious competitors – #**Get the impression that there has not been any significant competition – even Microsoft has Eclipse plugins – downloads are phenomenal – looking – java development package, for eclipse – 2.8million downloads, since SR2 – not counting the other different packages.  Get impression that community is growing, if anything
     • Wyatt: C//c++ and HPC is still a niche – most activity is in the java space –
     • Looking forward to 4E, will take some work to make things compatible, but will be worth it in the end
3. Status reports
   • Resource Managers
     • Still continuing to work on resource manager bug, hopefully have something in next week or so – hope to preserve as much backward compatibility for existing resource managers – just the jaxb resource managers that work differently – think there will be a different launch configuration
     • And a few issues to resolve – still want the XML configuration to specify the monitoring and control, don’t think it is api change –
     • Testing backwards compatibility, things still seem to be working
     • Just need to finish off new launching mechanism and a couple of new views, will have something to work on
     • New branch – sw RM (?) – not sure if pushed up to the main git repository
     • Anything else anyone needs to take on
   • Synchronized Projects
     • John – what is happening on synchronized stuff
     • Still working on relocation bug, this one is really involved, move the copies of big projects – doing a lot of refactoring, of lower level code & and how it works, this is needed to get it to be copied – refactoring is about finished.
     • Then will get back to merging tool –
     • One thing at summit: new project wizard – work is underway to provide a new-new-new project wizard, haven’t decided name of this – this is the CDT project wizard
       John has submitted a patch, several months ago, still waiting on this – this has not been committed – this is for CDT, Greg will ping the CDT
     • Bug# - 363612
     • Apptly doing a new more flexible project wizard, changing layout of the project types – Doug wants to make it more template driven, rather than being driven by project types – concern about complexity, not clear what the project types mean – will do some work to fix this, and make more user friendly, and wizard will become more customizable – will like to change the first screen, as we’d like to set up synchronized stuff first, before chose project type, need this flexibility – this would be possible – can have your own first page
     • But this shouldn’t stop us from fixing what is there now
     • Right now, John has it as single page, everything is set up on first page –
     • Default location is something we want to get rid of – we probably want to change what the first page looks like
     • Have you cloned the existing CDT wizard
     • Think copied a bunch of code from a variety of places, it is a bit of a mess –
     • Think the new structure of the new project wizard will make this easier, will have to wait and see
   • ETFW
     • Wyatt?
     • As you heard, Kevin is working on support for BG/P, and BG/Q – latter is challenging, personality for node layout is still being worked on and not likely stable yet
     • For ETFW, some stuff to get spiffed up for future releases, and scaling testing view – this is pretty handy for performance analysis side of things
   • Photran
     • Jeff? –not a whole lot on photran, mainly trying to get going on documentation for stuff added to PTP and for Blue Waters
   • GSI Authentication
     • And have been working on thing for Grid authentication, with ssh client, can do a myproxy logon – don’t have to logon everytime you drop or reestablish
     • Downside – have to patch the jsch implementation in platform, doesn’t seem to be hopeful to get this back into jsch via jcraft –
     • Platform patch – for this – can be done via update site at NCSA
     • Installs the same as a normal feature, but patches jsch feature in the platform –
     • Can we add extension point to jsch – this would be nice, but jsch doesn’t have any dependencies – we’d have to roll our own plugin mechanism, not sure how amenable they would be to doing this
     • They have support for multiple authentication mechanisms – but all hard coded in
     • Greg – think you are probably right about patching the platform.  Have you seen this documented somewhere – Jeff will look around – not sure what restriction was – not installed by default and use at your own risk – want to make sure we are good eclipse citizens
     • Greg will take a look to see if can figure out anything
     • If can do it through PTP, this would give us much better visibility
   • Dave Wooton
     • nothing new at this point
   • Chris Navarro
     • – mostly recently going through the bug list, submitted a patch for remote server extension point, the way the remote server manager, to see if there were any overrides for dstore – submitted a patch for this – problem was one extension point with 2 extensions – the way the code was getting the override was to assume the code was a separate extension, which it wasn’t –
     • 375674 is bug ID
     • Greg needs to take a look at this, think he wrote this code originally –
     • The multiple extension points were sharing an extension point, no way to get specific part of the extension point, without looking through configuration elements and see what they contain
     • For more significant things – get together with Chris – and Greg
     • Think about maybe something – carving off a bigger project for Chris to work on
4. PTP User Call
   • • Had a user call last week –
     • Jeff hosted it – thought it went well, Galen described how to use valgrind support in linux tools – had a really good discussion after that, heading off to discuss documentation, esp for using
     • 11 people on the call
     • Don’t have a topic for next month yet – one thing that thought on – was to look at python support in Eclipse,
     • People interested in doxygen – if there is anything to demonstrate there, we could do that
     • Python would be a good idea – in HPC community, a lot of interest in using python, driving hpc apps using python, and mentioned this at los Alamos – very interested
     • Jeff is interested in attending a XSEDE workshop on python in HPC – so is Greg, this is something we can look at for the next year or two – supporting python in HPC
5. Other Business
   • • One area – that we should add to the list of things for Chris to work on – getting linux tools to work with synchronized projects – and know Jeff Johnson working on some level of remote support
     • That was a discussion that we had, as basically with linux tools, written a proxy layer – that basically allows you to switch in different remote implementations – can use no remote support, or RSE, etc – all using extension points, so no dependencies on external packages, this closely mirrors what is in PTP, with our remote support – see if we can push PTP remote tools support up into CDT, this was well received by both linux tools and PTP – this is something that will be looking at over the next few months – Chris could be involved in this –
     • This is something  to add to the list
6. Next Meeting
   • • Anything else – May 8 is both next meeting and API freeze
