Abstract: Various aspects include a speaker including: an acoustic transducer for providing an audio output; a set of microphones for detecting a user voice command; and a controller coupled with the acoustic transducer and the set of microphones, wherein the controller is configured to: in response to detecting a power down command, switch the set of microphones from an active listening mode to a standby mode for a parking period, in response to detecting a power up command during the parking period, switch the set of microphones from the standby mode to the active listening mode after a first time period, and in response to detecting the power up command after expiration of the parking period switch the set of microphones from the standby mode to the active listening mode after a second time period that is greater than the first time period.

Abstract: A method for easily tracing the execution of an application in a computer system having a plurality of computing nodes interconnected by high speed data links is disclosed. While executing the application on one or more of the computing nodes, trace data is collected into a separate temporary trace buffer coupled to each computing node. A trace transfer request event may be generated after collecting a portion of the trace data. The trace data is recorded on a designated recording and analysis computing node by transferring the trace data from each trace buffer to a recording buffer in the designated recording node in response to the transfer request by performing memory mapped write transfers initiated by each computing node that has collected trace data. The address of the recording buffer is memory mapped into an address space of each computing node that has collected trace data.
