    Abstract: A method for implementing a spin lock in a system including a plurality of processing nodes, each node including at least one processor and a cache memory, the method including steps of: acquiring exclusivity to the cache memory; checking the availability of the spin lock; setting the spin lock to logical one if the spin lock is available; setting the spin lock to logical zero once processing is complete; and explicitly yielding the cache memory exclusivity. Yielding the cache memory exclusivity includes instructing the cache coherent hardware to mark the cache memory as non-exclusive. The cache memory is typically called level two cache.

    Abstract: A large-scale enterprise software system is described that outputs consistent export data for concurrent exports. The system includes a database and an export control module. The database stores modeling data defining a plurality of nodes, and enterprise data associated within each of the nodes. The export control module outputs a portion of the enterprise data as export data in response to an export selection that associates a set of the nodes with a least one export client. During the export process, the export control module creates an archive (e.g., a copy) of the enterprise data associated with one or more of the nodes for the export selection prior to modifying the enterprise data. The export control module utilizes the current enterprise data for the non-modified nodes and the archived export data for the nodes that were modified during the export process to output consistent export data for multiple, concurrent export clients.

    Abstract: Techniques are disclosed for allocation of resources under the control of resource managers and the choice and coordination of resource acquisition protocols to communicate with these resource managers. The resource managers may be distributed and heterogeneous. For example, a technique for use by a service provider for allocating one or more resources from multiple resources associated with multiple resource managers based on at least one service agreement offer from a service client comprises the following steps/operations. At least one service agreement offer is obtained. A resource allocation is automatically determined based on the obtained service agreement offer. The automated step/operation of determining the resource allocation comprises: (i) coordinating selection of a resource acquisition protocol from among multiple resource acquisition protocols for use in communicating with the multiple resource managers to acquire one or more resources associated therewith; and (ii) evaluating a performance associated with one or more of the multiple resource acquisition protocols.
