| − | #Attendees:
| |
| − | #*Jeff Overbey, John Eblen, Chris Navarro, Dave Wooton, Greg Watson, Jay Alameda, Wyatt Spear, on the call
| |
| − | #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<br>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
| |
| − | #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<br>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
| |
| − | #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
| |
| − | #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
| |
| − | #Next Meeting
| |
| − | #**Anything else – May 8 is both next meeting and API freeze –<br>
