Abstract: A system and method for optimizing system performance includes applying sampling based optimization to identify optimal configurations of a computing system by selecting a number of configuration samples and evaluating system performance based on the samples. Based on feedback of evaluated samples, a location of an optimal configuration is inferred. Additional samples are generated towards the location of the inferred optimal configuration to further optimize a system configuration.

Abstract: A communication system includes devices configured to communicate with each other through a temporal sequence of frames. Each of these frames includes multiple sub-channels and network information. Note that the network information in a given frame transmitted from a first device includes identification information for a second device that is communicating with the first device and corresponding sub-channels used by the first device and the second device to transmit data. Furthermore, the first device and the second device are configured to dynamically reserve one or more sub-channels based on the network information when communicating with each other, and dynamic-reservation conflicts may occur in which the first device and the second device both reserve a common sub-channel.
