Abstract: Systems and methods automatically design a system's architecture by modeling the architectural complexity of large-scale distributed systems to drive a partitioning and allocation algorithm. The result is a configuration based on the structure of the software tasks and data access, and the capacities of the hardware. Coupling and cohesion are relative, dependent on the ratio of load to capacity, and not independent software characteristics. The partitioning and allocation algorithm includes tradeoffs between processor utilization, memory utilization, inter-processor communication, and peripheral contention. The systems and methods take into account both precedence constraints and the directional flow of data. Further aspects include interleaving the decisions of database segmentation and software distribution. This approach is demonstrated with a simplified example of a real distributed system.

Abstract: A compression technique compresses interaction data. A fast method processes the compressed data without the need to first decompress the data. In one embodiment, the compression technique is used to compress data in an interaction matrix. The interaction matrix (such as a moment method impedance matrix) contains interaction data between sources (e.g., basis functions or expansion functions) and testers (e.g., testing functions). The sources are collected into groups of sources according to specified criteria. One useful criteria is based on grouping sources relatively close to one another. For each group of sources, a composite source is calculated. The testers are also collected into groups and composite testers are calculated. The use of composite sources and composite testers to compute couplings when the source and tester are not close to each other allows the interaction matrix to be computed as a sparse matrix with a block format.

Abstract: When a parameter for a numerical computation library is required, an optimum parameter reflecting a user policy is provided. A program calculates, based on a preset objective function, an optimum tuning parameter for executing a numerical computation library. The program reads the numerical computation library; reads the objective function; sets a user policy regarding speed performance and computational accuracy of the numerical computation library as plural policy parameters; reads, from preset execution histories of numerical computation libraries, execution histories of the numerical computation library; calculates, in a domain where the policy parameters are met and based on the execution histories having been read in, a tuning parameter for the numerical computation library by using the objective function; and outputs a calculation result of the objective function.

Abstract: An important component selection device is provided for selecting a component having a higher importance in a simulation calculation, so that the component having a higher priority is calculated firstly by a calculation device and the importance of the updated component is re-evaluated so as to be reflected in the calculation thereafter. When a high speed is required, the ranking of the important components are realized by hardware. Moreover, when a storage device has a plurality of candidate value data for each of the component data and the calculation device updates the candidate values one by one, the magnitude of variety of the candidate values is used as the importance of the component data and the component having this value which is large is calculated with a higher priority so that the calculation of the component having a small change is omitted, thereby increasing the simulation speed.

Abstract: A compression technique compresses interaction data. The interaction data can include a matrix of interaction data used in solving an integral equation. For example, such a matrix of interaction data occurs in the moment method for solving problems in electromagnetics. The interaction data describes the interaction between a source and a tester. In one embodiment, a fast method provides a direct solution to a matrix equation using the compressed matrix. A factored form of this matrix, similar to the LU factorization, is found by operating on blocks or sub-matrices of this compressed matrix. These operations can be performed by existing machine-specific routines, such as optimized BLAS routines, allowing a computer to execute a reduced number of operations at a high speed per operation. This provides a greatly increased throughput, with reduced memory requirements.

Abstract: A compression technique compresses interaction data. The interaction data can include a matrix of interaction data used in solving an integral equation. For example, such a matrix of interaction data occurs in the moment method for solving problems in electromagnetics. The interaction data describes the interaction between a source and a tester. In one embodiment, directional sources and/or directional testers are described. The directional sources produce a very weak (or negligible) effect except in selected directional regions. The directional testers are relatively insensitive to an incoming effect except in selected directional regions. Depending on their locations and directional properties, relatively many of the directional sources and directional testers interact weakly (or negligibly). The weak interactions can be effectively removed from the interaction matrix, thereby reducing the effective size of the interaction matrix.

Abstract: A technique for determining the number of constraints on, or topological dimension of, a set of input data produced by a nonlinear system, such as a pathological vocal or econometric system. The technique characterizes the tangent space about a predetermined base point by identifying a maximal set of non-redundant nonlinear fits to the data. It needs only a few data points and only assumes that the functional form of the true constraints is smooth. Each fit is equivalent to a set of contours, with the data lying along the zero-value contour. For each fit, the gradient at the base point in the uphill direction identifies the constraint direction. The number of linearly independent constraint directions provides the number of constraints near the base point. The remaining unconstrained directions define the tangent space, which has a dimensionality equal to the number of linearly independent unconstrained directions.

Abstract: A Driveline Angle Analyzer (DAA) for determining a torsional acceleration and inertias of a vehicle driveline by entering measurements of a vehicle driveline configuration into a graphical user interface program. The user selects the driveline configuration of interest from a plurality of driveline configurations. Then, the user enters information, such as driveline measurements relating to the selected driveline configuration. To aide in gathering the correct information, the user can print out a worksheet for the selected driveline configuration. After the user inputs the information for the selected driveline configuration, the user can select a corrective mode that allows the user to improve the selected driveline configuration. For example, the user can change the angle of a component with the surrounding components by changing their angles and/or length while enabling the components to stay connected to each other, thus maintaining the vehicle's driveline geometry.

Abstract: A software application implementable on a computer system is used to create a model of a hydraulic system to perform calculations. The user visually constructs a two-dimensional (2-D) connectivity model in the computer system. The 2-D connectivity model has a plurality of node points defined at various elements (sources, outlets, equipment, and junctions) of the hydraulic system and has segments interconnecting the node points. The user visually constructs a three-dimensional (3-D) segment model for each segment so that each segment model has the 3-D layout of the piping and the fittings for the segment. A 3-D system model of the entire hydraulic system is visually created in the computer system by combining the 3-D segment models. The software application performs calculations using the 3-D system model, and the 3-D system model can be visually or automatically verified to determine whether the model substantially corresponds to the 3-D layout of the hydraulic system, and has been laid out without errors.
