Abstract: A film layer comprising a high-chi (?) block copolymer for self-assembly and a surface active polymer (SAP) was prepared on a substrate surface that was neutral wetting to the domains of the self-assembled block copolymer. The block copolymer comprises at least one polycarbonate block and at least one other block (e.g., a styrene-based block). The SAP comprises a hydrophobic fluorinated first repeat unit and a non-fluorinated second repeat unit bearing at least one pendent OH group present as an alcohol or acid (e.g., carboxylic acid).

A master service has knowledge of or tracks the cloud service(s) to which a user is authenticated. Each cloud service may enforce its own inactivity period, and the inactivity period of at least first and second cloud services may be distinct from one another. When the master service receives an indication that the authenticated user is attempting to take an action at a first cloud service despite an activity timeout there, the master service issues a status request to at least the second cloud service to determine whether the user is still active at the second cloud service (despite its different inactivity period). If the user is still active at the second cloud service, the master service provides a response, selectively overriding (re-setting) the activity timeout at the first cloud service to permit the action.

Abstract: A technique for safely rolling back transactional memory transactions without impacting concurrent readers of the uncommitted transaction data. An updater uses a transactional memory technique to perform an data update on data that is shared with a reader. The update is implemented as a transaction in which the updated data is initially uncommitted due to the transaction being subject to roll back. The reader is allowed to perform a data read on the uncommitted data during the transaction. Upon a rollback of the transaction, reclamation of memory locations used by the uncommitted data is deferred until a grace period has elapsed after which the reader can no longer be referencing the uncommitted data.

Abstract: Managing requests for acquiring resources in a computing environment. A first request to acquire resources is received. Whether the resources have been pre-acquired is determined. If the resources have not been pre-acquired, a token registering interest of a first thread in the first request is subscribed to. If the acquisition of the resources is not successful, whether a prior synchronous request has been initiated by a thread for the first request is determined. If a prior synchronous request has not been initiated, a synchronous request is initiated to acquire the resources. If the resources have not been pre-acquired for a second received request, an interest is registered of a second thread in the first request using the token. If the acquisition of the one or more resources is successful, a thread is notified of the successful acquisition, and the interest of the second thread is unregistered in the first request.

Abstract: A method, system and computer program product for handling an increase in transactional data load without requiring the relocation of preexisting data. A range of attribute values and identifications of associated shards are stored in a data structure. In response to adding a new shard, the data structure is updated by associating a range of attribute values to the added shard while maintaining the same range of attribute values being associated with one of the pre-existing shards. As a result, the new data assigned within this range of attribute values will be stored in the newly added shard while the older data assigned within this range of attribute values will continue to be stored in one of the preexisting shards. In this manner, an increase in transactional data load can be handled by adding a new shard without requiring the relocation of preexisting data.

Abstract: A job optimizer dynamically changes the allocation of processing units on a multi-nodal computer system. A distributed application is organized as a set of connected processing units. The arrangement of the processing units is dynamically changed at run time to optimize system resources and interprocess communication.

Alternatively, the job optimizer may determine to split a job's processing units into multiple jobs on different nodes where one or more of the processing units are over utilizing the resources on the node.

Abstract: A cloud enablement aggregation proxy (CEAP) receives and processes audit data from audited resources before such data is stored in a database. The CEAP manages log data for resources hosted in a multi-tenant shared pool of configurable computing resources (e.g., a compute cloud). A method for managing log data begins by the proxy aggregating and normalizing log information received from a plurality of the resources. The aggregated and normalized log information is then parsed to identify a tenant associated with each of a set of transactions. For each of the set of transactions, the CEAP annotates log data associated with the tenant and the particular transaction to include a tenant-specific identifier. An optional tenant separation proxy (TSP) separates the annotated log data on a per tenant basis prior to storage, and the tenant-specific log data may be stored in per tenant data structures or dedicated tenant log event databases to facilitate subsequent compliance or other analysis.

Abstract: An identity of a user performing an operation with respect to an application is propagated, from a point at which the user authenticates, to one or more other applications in a multi-product environment.

As the application performs one or more management operations, audit events are logged, and these events each contain the identity that has been passed in by the management console during the SSH/RXA login.
