Systems and methods to implement performance monitoring of a device under test involve defining one or more sequences. Each of the one or more sequences includes two or more events, each of the two or more events being defined by one or more hardware signals that include a hardware register value, transmission of a message or signal, or a wire voltage change. A method includes initiating a simulation of the device under test by inputting one or more signals at one or more inputs of the device under test for propagation across the device under test, and monitoring completion of the two or more events defining each of the one or more sequences. Performance of the device under test is reported. Reporting includes providing latency of each of the one or more sequences. A final design of the device under test is provided for fabrication based on the performance monitoring.

Triggered sensor data capture in a mobile device environment. A method monitors primary sensor data obtained from first wearable sensor device(s) to determine whether trigger condition(s) are met for triggering supplemental sensor data capture. Based on recognizing a health event, the method obtains health status input from a user, configures second wearable sensor device(s) to obtain supplemental sensor data that includes additional data in addition to the primary sensor data, and obtains the supplemental sensor data. The method provides the health status input and the obtained supplemental sensor data as correlated health event data of the health event for analysis. Based on the analysis, the method tunes at least one trigger condition of the trigger condition(s) to adjust a scope of supplemental sensor data capture.

A method for enhanced digital content presentation is provided that includes assigning, to each member of members of a social network of a user, a respective knowledge score, the knowledge score being representative of accuracy in the member predicting positive impressions of the user. The members of the social network are surveyed for an indication of which one or more options for digital content are expected to have a positive impression on the user. Based on the surveying, selected digital content based on the one or more options that are expected to have a positive impression on the user, as indicated by the surveying, is selected. The selected digital content is presented to the user. An indication of whether the selected digital content had a positive impression on the user is received from the user.

Embodiments include methods, systems and computer program products method for maintaining ordered memory access with parallel access data streams associated with a distributed shared memory system. The computer-implemented method includes performing, by a first cache, a key check, the key check being associated with a first ordered data store. A first memory node signals that the first memory node is ready to begin pipelining of a second ordered data store into the first memory node to an input/output (I/O) controller. A second cache returns a key response to the first cache indicating that the pipelining of the second ordered data store can proceed. The first memory node sends a ready signal indicating that the first memory node is ready to continue pipelining of the second ordered data store into the first memory node to the I/O controller, wherein the ready signal is triggered by receipt of the key response.
