  • Publication number: 20140099769
    Abstract: Isolation trenches are etched through an active silicon layer overlying a buried oxide on a substrate into the substrate, and through any pad dielectric(s) on the active silicon layer. Lateral epitaxial growth of the active silicon layer forms protrusions into the isolation trenches to a lateral distance of at least about 5 nanometers, and portions of the isolation trenches around the protrusions are filled with dielectric. Raised source/drain regions are formed on portions of the active silicon layer including a dielectric. As a result, misaligned contacts passing around edges of the raised source/drain regions remain spaced apart from sidewalls of the substrate in the isolation trenches.

  • Publication number: 20140074872
    Abstract: Relational database modeling and triggers are employed and coordinated to maintain and manage tunable parameters and characteristics of a Workload Optimized System. The database model is initialized with pre-defined values as per definition of Workload Optimized Systems, which models the optimal configuration of the workload-optimized system, capturing various performance configurations, security and other related system and software configuration. The values present the optimal values for the entire solution. A daemon is run to monitor for changes in the tunable configuration settings, which also updates the current values of the configuration parameters on the RDBMS. SQL Triggers are implemented on the database to identify cases where corrective actions are required to the configuration parameters.

  • Publication number: 20140019574
    Abstract: Byte utilization is improved in Remote Direct Memory Access (RDMA) communications by detecting a plurality of concurrent messages on a plurality of application sockets which are destined for the same application, client or computer, intercepting those messages and consolidating their payloads into larger payloads, and then transmitting those consolidated messages to the destination, thereby increasing the payload-to-overhead byte utilization of the RDMA transmissions. At the receiving end, multiplexing information is used to unpack the consolidated messages, and to put the original payloads into a plurality of messages which are then fed into the receiving sockets to the destination application, client or computer, thereby making the consolidation process transparent between the initiator and the target.

  • Publication number: 20140006854
    Abstract: File system errors are handled and computing systems are recovered by, responsive to receiving a page buffer request, initializing a sleep timer according to a detection interval value plus a hang resolution range value; responsive to the timer expiring, detecting that a process, thread, application program, daemon, or task is waiting on availability of the requested page buffer; and responsive to the detection, quarantining metadata associated with the requested page buffer, failing the page buffer request and releasing one or more locks on the requested page buffer. This process is then optionally repeated for additional processes, threads, application programs, daemons, tasks or combinations thereof which are waiting for availability of the requested page buffer, optionally randomizing the detection interval value in order to avoid an instantaneous recovery from the error.

  • Publication number: 20130341937
    Abstract: Electrical power is generated from falling liquids such as captured rain water, gray water and black water in tall buildings using two or more reservoirs. Fill valves for each of the reservoirs are controlled to fill the first reservoir in a raised position while emptying the second reservoir in a lowered position. When full, the first reservoir is dropped to the lowered position while imparting mechanical energy to an electrical generator and while raising the second reservoir. Next, the second reservoir is filled until full while the first reservoir is emptied, followed by dropping the second reservoir to the lowered position while imparting mechanical energy to the electrical generator and while raising the first reservoir. The cycle is repeated so that electrical generation from the falling of the liquid avoids the liquid contacting or passing through a turbine or impeller.

  • Publication number: 20130332913
    Abstract: Performance impact of a computing system component on a transient end-to-end system operation is estimated by profiling an overall characteristic for a transient end-to-end system operation, and simultaneously profiling a program code component for a second characteristic, thereby collecting a first pair of data points, repeating the operational period while introducing a known artificial delay into the program code component, and while profiling the overall performance characteristic for the system and for the program code component, thereby collecting pairs of data points for each repetition of the operational period for each of the artificial delays; curve fitting and analyzing intercepts of the collected data points to estimate the effect of the artificial delays in the program code component on the transient end-to-end system operation; and reporting the estimate correlated to potential optimal transient end-to-end system operation.

  • Publication number: 20130133062
    Abstract: A system for automatically completing fields in online forms, such as login forms and new user registration forms, which employs a Master Cookie File containing sets of records associated with the user, his or her accounts or web sites, and registered values associated with form tags (e.g. username, password, address, email, telephone, etc.). When the user encounters another form, the MCF is automatically searched for matching values and form tags, primarily from the same account or web site, or alternatively from other accounts or sites. A flowing pop-up menu is displayed nearby the form fields from which the user can select values to automatically complete the form. Automatic account information updating, value expiration management, mapping of favorite values, and sharing of values are optional, enhanced functions of the invention.
