Appl. No.:

10/278345

Christopher Dickson - Edina MN, US
David Caliga - Colorado Springs CO, US

Assignee:

SRC Computers, Inc. - Colorado Springs CO

International Classification:

G06F 13/28

US Classification:

710 22, 709212, 709213, 709215, 711147

Abstract:

Embodiments of the invention include a mechanism for explicit communication in a clustered multiprocessor system that supports low-latency, protected, user-mode, communication across the machine boundaries of a clustered multiprocessor. Data transport may be accomplished over persistent, unidirectional, point-to point connections, each of which may be embodied in a small amount of state at each end, along with a statically allocated per-connection memory buffer, which may be directly accessible to the transport mechanism at both ends of each notional link. System Memory protection may be afforded by operating system (“OS”) facilitated allocation of both restricted control of the network interface, and responsibility for data transport, to an application thread that may execute in the context of the processor-managed virtual address space. Connection buffer protection may be afforded by restricting access to connection state to those entries associated with the currently controlling thread.

Abstract:

The disclosed computer-implemented method for aggregating information-asset metadata from multiple disparate data-management systems may include (1) receiving a first instance of metadata of an information asset from a first data-management system that manages information assets of an entity in a first domain, (2) receiving a second instance of metadata of the information asset from a second data-management system that manages the information assets of the entity in a second domain that is separate and distinct from the first domain, (3) storing the first and second instances of metadata in a global metadata repository that is separate and distinct from the first and second data-management systems, and (4) providing access to the first and second instances of metadata stored in the global metadata repository to the first data-management system, the second data-management system, and/or the entity. Various other methods, systems, and computer-readable media are also disclosed.
