An integrated risk management tool includes a persistent object database to store information about actors (individuals and / or groups), physical surroundings, historical events and other information. The risk management tool also includes a decision support system that uses data objects from the database and advanced decision theory techniques, such as Bayesian Networks, to infer the relative risk of an undesirable event. As part of the relative risk calculation, the tool uses a simulation and gaming environment in which artificially intelligent actors interact with the environment to determine susceptibility to the undesired event. Preferred embodiments of the tool also include an open “plug-in” architecture that allows the tool to interface with existing consequence calculators. The tool also provides facilities for presenting data in a user-friendly manner as well as report generation facilities.

A memory management system is disclosed having a first memory heap module that assigns newly created objects to a first memory category and assigns persistent objects to a second memory category. The memory management system further assigns infrequently accessed persistent objects to a third memory category. A garbage collecting module collects garbage on objects in the first and second memory categories, but does not access objects in the third memory category. An operating system pages inactive objects assigned to the third memory category to a stable store. A user can debug the system, checking how many objects are assigned to the third memory category, and how many objects assigned to the third memory category are not accessed after initial allocation. Objects can be assigned to the third memory category based on selected criteria including time since access, likelihood of future object access, object size, and object priority.

A method, system and computer program product for reducing garbage collection pause time. According to example embodiments, a garbage collection cycle is initiated on a set of objects that have been dynamically allocated in a memory. An identification is made of new persistent objects and reachable non-persistent objects while ignoring old persistent objects that have been identified as persistent in previous garbage collection cycles. The new persistent objects are associated as members of a set of persistent objects that includes the old persistent objects. The persistence information for the set of persistent objects is preserved for use during subsequent garbage collection cycles. All reachable non-persistent objects and all persistent objects in the set of persistent objects are marked for memory reclamation phase processing. The persistent objects are so marked using the preserved persistence information such that repeated scanning of persistent objects during multiple garbage collection cycles is avoided.

A system and method are disclosed for an interactive multimedia file (iMF), running on an interactive multimedia runtime (iMR), to store an object onto a computer, the method comprising creating a local instance of the object, storing the local instance into a memory location on the computer, monitoring changes to one or more data slots of the local instance, assigning a version identifier to the local instance, synchronizing the local instance with a main instance of the object, and interfacing the one or more data slots of the local instance with said iMF during execution.
