Re: [science-iwg] IDataSet in EAVP

Jay,

 

>> the whole community, me included, really wants to be able to use IDataSet with EAVP

Perfect! What is the blocker in using it right now?

 

I suggest to put it in EAVP from where it is, it is there on the eclipse github and EPL licensed. Import statements can be changed later and eclipse projects can depend on one another after all.

 

Tim suggested sciDataset, so perhaps the eventual package/project could be org.eclipse.scidataset? But before we do that, I would like to quantify the need from the community of its location.

 

Given that it is two plugins, it should be pretty easy to create a project for it faster than EAVP and ensure that EAVP can make its targets for releasing with the Eclipse train; if that is the blocker.

 

Best Regards,

 

Matt

Matt,

Will you please clarify your response and be a little more definitive please? My feeling is that the the whole community, me included, really wants to be able to use IDataSet with EAVP. I am essentially trying to figure out if this is something that we can plan and push for as part of our 1.0 release in 6-12 months or if it needs to wait until a 2.0 release sometime after that.

So, are you saying that you don't know what you're going to do with it yet? Or are you saying that you want to propose a new "data structures" project that we could wait on?

Even a statement of "I need more time to investigate this" would be fine, just as long as you say it unequivocally, because then I can put it on the potential feature set for the EAVP 2.0 release next year and leave it out of 1.0.

Hello Jay and other folks,

 

>> Alex noted that you felt like the "moving IDataSet" option would make EAVP a competitor to DAWNSci.

To clarify, I said was that at the point where EAVP does not use IDataset, it becomes a competitor to DAWNSci J This is because the numerics become less compatible but the scope is the same. If the numerics are compatible it becomes a collaborator with a similar scope.

 

I think our vision for IDataset is not a visualization specific project but something more general, just as numpy is for python. IDataset is two plugins with few dependencies. Suggestions about where it sits not specific to any single use case (visualization, numerics, scripting, etc) are welcome.

 

If we do move, we might need a name like numjy, jDataset etc. for the project, again suggestions welcome! There would also be some Diamond internal work for me to consider and agree, likely not a blocker although I might ask external people register specific interest in how they will reuse it and why they want it moved.

 

I also reported in the meeting that IDataset is complete but can be faster for some operations. When/if speed issues arise, there are a number of strategies which can be used already or new code added J It can deal with data much larger than available memory, which is a powerful way at looking at large data on small computers.

Everyone,

I should clarify that EAVP is short for "the Eclipse Advanced Visualization Project" for those who haven't heard of it before. It is the viz project that we have been discussing for awhile.

Matt,

I met with Alex this morning and he told me how awesome the Norway meeting was. He also told me that there is broad support for using IDataSet in EAVP. I would like to discuss how we can move forward on this. I strongly support the use of IDataSet in EAVP and I really want to see a tight integration because it is technology that would be very valuable to what we are doing at ORNL and, I imagine, other institutions in this group. There is a very big technical question that we need to answer though: Where is IDataSet going to be released?


In one of our previous steering committee calls you said that DIAMOND has no intention of doing a "full Eclipse release" of DAWNSci since your goal with the project was only to release the source code, not binaries. That makes it very challenging to use anything in DAWNSci in any other SWG project because it lacks that Eclipse "technical goodness" that many of our projects depend on.

So, if you don't mind, let's start there. What are your release plans for DAWNSci? If you are planning an official, Eclipse.org release then I think we can use IDataSet as it is and just wait on your release. However, if not or if not reasonably soon, then I think you should seriously consider contributing it to EAVP so that the community can use it and help develop it with you.

Alex noted that you felt like the "moving IDataSet" option would make EAVP a competitor to DAWNSci. I don't personally see that since no other Eclipse projects are competitors to DAWNSci. I urge you not to look at the project that way either. It is meant to be an open, community effort that we all work on - and use - together.

Please let me know what you think and let's keep this discussion in the open so that we can get good thoughts and ideas from the community. I'm certain there is a workable path forward on this.

Jay
