Systems and methods include a predictor module configured to receive an input, e.g., composition parameters and processing parameters. A processor processes the input to predict a material property, e.g., fatigue strength, of an alloy based on the input. The processor outputs the predicted fatigue strength of the alloy for display.

System and method for predicting fatigue strength of alloys

Method of analyzing data from an online social network having a set of network users. The method includes obtaining topic-specific messages sent by the network users. The messages have social content provided by the networks users, wherein the messages include a marker of interest in the social content. The marker of interest is associated with a topic of the social network. The method also includes identifying the network users that sent the messages having the marker of interest in the social content as interested users of the topic. The interested users are a subset of the set of network users. The method also includes determining a topic-specific influence (TSI) value of a designated user from the interested users in the subset. The TSI value of the designated user is based on a number of the interested users that are registered to receive the messages from the designated user.

Systems and methods for controlling power consumption in a computer system. For each of a plurality of interactive applications, the method changes a frequency at which a processor of the computer system runs, receives an indication of user satisfaction, determines a relationship between the changed frequency and the user satisfaction of the interactive application, and stores the determined relationship information. The determined relationship can distinguish between different users and different interactive applications. A frequency may be selected from the discrete frequencies at which the processor of the computer system runs based on the determined relationship information for a particular user and a particular interactive application running on the processor of the computer system. The processor may be adapted to run at the selected frequency.

A method for processing using a shared file that includes allocating a first working buffer between the shared file and a plurality of address spaces, wherein each of the plurality of address spaces is associated with one of a plurality of processors, copying first data from the shared file to the first working buffer by a first aggregator copying the first data from the first working buffer to the plurality of address spaces by the first aggregator, processing the first data, in parallel, by the plurality of processors to obtain a result, wherein the plurality of processors access data from the plurality of address spaces, and storing the result in the shared memory.

Method and system for file access using a shared memory

A method for processing using a shared file that includes creating a plurality of mmaps between a shared file and a plurality of address spaces, wherein each of the plurality of mmaps maps at least a portion of the shared file to one of the plurality of address spaces, and wherein each of the plurality of address spaces is associated with one of a plurality of processors, transferring, in parallel, data between the shared file and the address spaces using the plurality of mmaps associated with the plurality of address spaces, processing the data in parallel by the plurality of processors to obtain a result, wherein the plurality of processors access data from the plurality of address spaces, and storing the result in the shared memory.

Electronic design automation tool specifies an architecture at a system level and its component (which include intellectual property (IP) cores like embedded processors, arithmetic logic units (ALU), multipliers, dividers, embedded memory element, programmable logic cells, etc.); specifies IP-cores and their interface; and understands IP-cores and functions via their interface. Further, techniques are provided for modeling the timing behavior of a function or functional block without drawing a timing diagram; understanding the interface behavior of a function block which captures the timing waveforms; specifying virtual functions which are built using basic functional units and their timing behavior; parsing and creating an internal graphical form for analyzing a specification for compilation; matching the components in the architecture specification and their instantiation to map the computations in the input graph produced from an application; and mapping the specification onto the target's components.

System for architecture and resource specification and methods to compile the specification onto hardware

Digital circuit is synthesized from algorithm described in the MATLAB programming language. A MATLAB program is compiled into RTL-VHDL, which is synthesizable using system-specific tools to develop ASIC or FPGA configuration. Intermediate transformations and optimizations are performed to obtain highly optimized description in RTL-VHDL or RTL Verilog of given MATLAB program. Optimizations include levelization, scalarization, pipelining, type-shape analysis, memory optimizations, precision analysis and scheduling.
