Abstract: Termite trailing and recruitment compositions, systems, devices, and methods for using a trail of a percentage 2 phenoxyethanol (2-PE) dissolved in water to form a trail to lead the subterranean termites to termite bait or monitoring stations located about a perimeter of a wood containing structure. The termite bait or monitoring stations can be located up to approximately 20 feet apart from one another, and the trail of a percentage 2 phenoxyethanol (2-PE) dissolved in water. The percentage 2 phenoxyethanol (2-PE) dissolved in water range from approximately 0.1% to approximately 2% depending on the different soil types and localized conditions. The types of soil can commonly include sand, sandy & silty soil, loam and clay soil.

Each GPU driver submits tasks for processing only if its respective firmware state register indicates that the GPU firmware is online. The GPU processes tasks for an operating system if the respective OS state register of that operating system indicates that the GPU driver is online.

Abstract: A method of configuring a graphics processing unit includes generating configuration data that specifies a configuration to be adopted by the graphics processing unit. The configuration data is received at the graphics processing unit, which is configured in accordance with the configuration data by writing the configuration data into one or more registers of the graphics processing unit.
