Embodiments of the present invention provide a method, system, and computer program product for optimizing I / O operations performed by a storage server operating on behalf of multiple clients to access data on a plurality of storage devices (disks). Embodiments of the present invention eliminate the need for selected read operations to write new data to physical data blocks by zeroing the physical data blocks to which new data will be written. Additionally, the need for reading old parity to compute new parity is eliminated. Instead, new parity is computed from the data to be written without the need of old parity or the storage server sends a command to a disk that stores parity. A module implemented at the disk that stores parity executes the command without reading, by the storage server, old parity. Eliminating the need for reading old data and for reading old parity eliminates some rotation latency and improves overall system's performance.

The nucleation delay in the formation of a tungsten layer on a substrate is reduced or eliminated by alternative processes. In one process the substrate is exposed to atomic hydrogen before the tungsten nucleation layer is formed. In the other process the substrate is exposed to a boron hydride such as diborane (B2H6) before the nucleation layer is formed. The process works effectively to reduce or eliminate the tungsten nucleation delay on a variety of surfaces, including silicon, silicon dioxide, silicon nitride and titanium nitride.

Under the present invention, a history of requests for data objects are tracked and maintained in a cache log. Based on the history, certain data objects are prefetched into a cache. When a request for a cached data object is later received, the requested data object can be retrieved from the cache and served to the requesting user. Thus, the latency involved with obtaining the data objects from the appropriate sources is eliminated. Further, under the present invention, discard and refresh rules are assigned to each data object on a class basis. Accordingly, data objects in the cache can be refreshed and / or discarded so that the caching operation can be optimized.

A market management system is designed to manage energy industry standardized transactions between energy providers and utility distribution customers. The system includes business process and transaction validations along with transaction tracking. The market management system processes transactions in its own data format but stores the transactions in a client's customer information system (CIS) using the CIS's data format. Using only the CIS database for transaction storage eliminates the need to synchronize transaction records in the CIS database with records in a market management database. Exception management is integrated with the CIS to eliminate duplication of effort. The market management system's functionality is scalable such that varying levels of service may be provided to customers. Predetermined business rules may be customized for the purpose of validating transactions.

This invention describes a secure peer-to-peer payment system based on the use of a virtual currency, virtual accounts, and a public payments ledger. The virtual currency used in the system is stable, as it is pegged to real-world currencies with unit values equivalent to the national currency of the country of deployment. The virtual accounts are specially designed and cryptographically encapsulated objects that can be opened (created), initially loaded, cleared (suspended / terminated), and used (credited / debited) for direct account-to-account payments. Validation of payment transactions is supported by a public payments ledger that prevents the use of the system by illegal or unauthorized users, eliminates illegal payments, prevents the use of illegal currency, and double-spending. The ledger contains instances of virtual accounts, so validation of payments is instantaneous based on the validation of the balances of the two participating accounts. Validation protocol can be at several assurance levels, reflecting user needs, financial policies, and the value of the payment transactions. The system has no third parties and uses community validation protocols. Furthermore, it does not store any secret, private, or sensitive user credentials, so it is not vulnerable to any type of attack. It provides full security, privacy, and anonymity for users, their virtual accounts, and their payment transactions.
