Abstract: Method and systems configured for allowing a non-local remote user to access a computer system with a particular authorization level. Such access is facilitated by examining non-local directory services group memberships of the user and performing a mapping of the user's identity to a corresponding universal local user account that have the proper authorization level or levels. Such methods and systems allow any number of non-local remote users access to the computer system in such a way that the remote user assumes the identity of (i.e., is mapped to) a corresponding universal local user account of an appropriate privilege level. All non-local remote users that the computer system determines to be of the same privilege level will share the identity of the same universal local user account.

Abstract: A method for facilitating handling of exceptions in object code transformed from a 1-to-1 threading model to a M-to-N threading model comprises transforming object code having a 1-to-1 threading model to a M-to-N threading model, saving context of a Runnable section of the object code into a context object in response to an exception occurring and rethrowing the exception after performing the saving. The transforming includes creating a Boolean enable value in a method context for an exception handler in the method context, mapping an exception type to the exception handler and wrapping a Runnable section of the object code within a respective synthetic exception handler. The respective synthetic exception handler is configured for saving context of the object code Runnable into a context object in response to an exception occurring and rethrowing the exception after performing the saving.

Abstract: Network topology codes are computed and used as keys to retrieve topology-specific information for isomorphic networks.
