Speaker: James Kowalkowski

  Offline analysis and reconstruction programs are controlled and configured using the D0 offline framework package. This package incorporates many object-oriented techniques and patterns to make it highly extensible in terms of algorithms and operational characteristics with very low coupling to outside packages. Activities and algorithms are run-time configurable without recompilation. Several subsystems work together to provide the execution environment: a dynamic algorithm registration system, grouping and sequencing components for state machine-like behavior, a user extensible, dynamic message distribution system, and a high level control interface. A set of interactive components that make use of multithreading are being developed along with a CORBA ORB for distributed operation, mixed language use, and support of other services such as database interactions.
