Mixed-Initiative tool to speed Up content creation in physics-based games
… work we introduce a mixed-initiative tool to speed up the process of con- tent generation for physics-based games. Our system uses exhaustive search and computational geometry to allow the game designer to focus on the creative process of content creation by not needing to worry about the …

Use of architectural-level primitives in system-level diagnosis and speed up of test vector generation
Test generation is an important part of a circuit as the test vectors are used during the design, manufacture, system integration, and throughout the life-cycle of the circuit in order to detect the presence of defects. The very large scale integration (VLSI) test generation problem has been one of …

Accelerating induction machine finite-element simulation with parallel processing
… to determine if using GPUs for calculations can speed up the simulation. The dominant steps of the finite element simulation are preconditioner formation, computation of the sparse iterative solution, and matrix-vector multiplication for magnetic flux density calculation. Due to the sparsity of …

Improved performance of the hPIC particle-in-cell code by incorporating a new non-uniform implicit mesh based on the PUMI infrastructure
… reducing the memory footprint, with a resulting speed up of the execution. The field solver for hPIC has been updated to comply with mesh non-uniformity. On top of the non-uniformity, the algorithm allows the splitting of the entire plasma domain into a number of blocks, termed as submeshes. The …

Preconditioned conjugate gradient methods for the Navier-Stokes equations
… Navier-Stokes equations are cast in an implicit, upwind finite-volume, flux split formulation. Preconditioning techniques are employed with the Conjugate Gradient like method to enhance the stability and convergence rate of the overall iterative method. The superiority of the new solver is …

Dilemma of speed vs. scale in software system development best practices from industry leaders
Many startup organizations face a dilemma as they scale up and their systems grow more complex. This dilemma is between the speed of releases i.e. agility and the scalability of their systems, reflected in the performance, stability and maintainability of their systems as they become larger. A …
