***They're moving ahead with advanced IBP clients (reader/writer) using Java.  They want a new client version ready for demo.
**LoDN_Brazil (http://dvnserver.pop-sp.rnp.br)
***The storage working group is up for review. They're going to show their version of LoDN.  It can use either the L-Bone or StoreCore for resource discovery. The integration is done in the WebStart client. There can be user defined volumes added to the store core. This allows people to share a common IBP infrastructure but can also contribute their own. The model they're presenting is a public resource that RNP controls, but which you can add to, but you can also add resources that only.
***Micah made a point about the problems that we need to watch for with regard to how the different versions of LoDN are evolving manage policy and  what that means when you give an exnode to a directory. Hunter's group is doing things like adding group access policy, etc. Need to choose a simple permission structure that people can standardize on.

    • Description of Jian's Demo:

Creating a multiuser visualization facility based on distributed and heterogeneous resources has proved to be an elusive challenge for the high performance computing and visualization community. We have developed a highly deployable solution to this problem. Our solution uses a collection of freely available, unscheduled and unreserved storage and computing resources, distributed across the network, to provide the essential infrastructure that such a visualization facility needs. Our demonstration will show that large scale visualization of cutting edge simulation datasets can be shared among multiple distributed users from the same pool of distributed resources, requiring only a standard Internet connection for each user.

    • Working with Ultralight? We don't know what's being planned here.
    • Working with OSG/Fermi? We don't know what they're planning.
    • Martin is doing a bandwidth challenge with Phoebus. It's not all-TCP-Phoebus. This demo is with Internet2.
    • Engaging with ORNL about standing up an L-Store/SRM at their site.
    • Status of Ultralight plans (Alan)
  • Plans for Internet2 Side meeting (Terry, Micah)
