  4. Organizational • V4 development team is developing all of the V4 infrastructure for PVData and Communication, compatibility with V3, Normative Types, and General Services • Control System Studio is developing an integrated operator environment in an integrated product. • DISCS is developing RDB applications over a full range of control requirements.

  5. Organizational • V4 development team: Marty Kraimer, MatejSekoranja, NikolayMalitsky, GuobaoShen, David Hickin, TimoKorhonen, Bob Dalesio, Andrew Johnson, with Greg White as team lead. • Control System Studio: Gabriele Carcasi, KunalShroff, Kay Kasemir, Xihui Chen, with Eric Berryman as team lead. • DISCS: Has a host of developers working on at least 17 domains with VasuVupala as team lead. • Developers meetings will proceed as joint development meetings with a nominal 4 months frequency that will rotate between the developer’s sites.

  6. Normative Type Progress • Types in use are: all NT Types that support DBR Types, NT_Table, NT_Image(areaDetector Support), Multi-Channel Array, and NT_Variant Array. • Unions are supported now and this improves the implementation of the NT_VariantArray. This type is a collection of heterogeneous types that can be scalars or vectors. MASAR needs to be refactored to use this implementation. • NT_NDArray is defined and will be prototyped in the experimental area for delivering large multidimensional arrays of coordinates and binned data.

  7. Highlights • Developments in the three areas are being integrated and deployed at member labs. • PVAccess has started to add multicast. • V4 and CSS Release methods to support continuing development when the release cycle begins and to harden a release with bug fixes. • Multicast implementation is started. This uses a topic name for listeners. • Working to Improve monitor performance to minimize header data. • Access security is needed from DISCS group for PVAccess security and to complete Channel Finder as a V4 service. • Fast array support in the V3 IOC to support large data sets. • Replace XML RPC • Will standardize on CAJ – pure Java. Hardening is being addressed. • Many of the NTTypes are mapped to Vtypes in PVManager for V4 and CSS integration. • Deployments into production environments at NSLS II and FRIB are hardening the developments in all three areas. Many of the applications are in full production.

  8. Conclusions • There is a strong and active development team in these three areas that is coming together to bring middle layer services that will be applied to physics and experimental control and data acquisition. • The underlying performance and flexibility that has been created by Marty Kraimer and MatejSekoranja has provided a strong base for the development of these new middle layer services. • The next 18 months will see many of these deployments go into production. During this phase, the applications will harden and move to production quality. • If you are interested in helping to develop in any of these areas, there are a lot of opportunities to get involved.
