Automated configuration parameter tuning for database performance
Embodiments implement a prediction-driven, rather than a trial-driven, approach to automate database configuration parameter tuning for a database workload. This approach uses machine learning (ML) models to test performance metrics resulting from application of particular database parameters to a database workload, and does not require live trials on the DBMS managing the workload. Specifically, automatic configuration (AC) ML models are trained, using a training corpus that includes information from workloads being run by DBMSs, to predict performance metrics based on workload features and configuration parameter values. The trained AC-ML models predict performance metrics resulting from applying particular configuration parameter values to a given database workload being automatically tuned. Based on correlating changes to configuration parameter values with changes in predicted performance metrics, an optimization algorithm is used to converge to an optimal set of configuration parameters. The optimal set of configuration parameter values is automatically applied for the given workload. |

Limiting replay of load-based control independent (CI) instructions in speculative misprediction recovery in a processor
Limiting replay of load-based control independent (CI) instructions in speculative misprediction recovery in a processor.

Liquid crystal tunable plasmonic color generation device, method and applications
Color derived from metallic nanostructures are often more efficient, more robust to environmental changes, and near impossible to damage or bleach due to overexposure. The embodiments combine these advantages with the millisecond re-configurability of liquid crystals to actively control a reflective color of a metallic nanostructure. Of the current technologies that boast active color tunability, many are pigmentation based (e-ink in e-readers) and/or need seconds to change color (photonic ink, electrochromic materials). Speed is an advantage of the embodiments and is comparable to current liquid crystal displays (˜120 Hz). Traditional LC displays use static polymer films (color filters) and white back light to generate color. Being able to actively tune the color from a single metallic nanostructure allows for smaller pixel size, increased resolution, and decreased fabrication cost compared to a conventional RGB color pixel without needing external white light source for extremely low power operations. |
