Abstract: Aspects of the invention include tracking relative ages of instructions in a first-in-first-out (FIFO) issue queue of an out-of-order (OoO) processor. The FIFO issue queue is configured to add instructions to the issue queue in a sequential order and to remove instructions from the issue queue in any order including a non-sequential order. The tracking of relative ages of instructions includes maintaining a head pointer to a location of an oldest instruction in the issue queue and a tail pointer to a location of a last instruction added to the issue queue. It is determined periodically whether the tail pointer is pointing to a location that includes a valid instruction. The tail pointer is updated to point to a previous sequential location in the issue queue based at least in part on determining that the tail pointer is not pointing to a location that corresponds to a valid instruction.

The system for member relevance prediction may predict a third data set related to member interactions using the first model and aggregate the first data set, the second data set, and the third data set. The system for member relevance prediction may train a second model for the second platform using the aggregated platform data and predict for the second platform, using the second model, online service items for the member.

Abstract: Techniques are disclosed for managing gateway switchovers. An indication is received that a primary gateway will be switched to a backup gateway. In response to the indication, a response is made to a periodic health probe that a gateway switchover has been initiated. Incoming data traffic is forwarded from the primary gateway to the backup gateway. Subsequent to an elapsed time delay, a response is made to the periodic health probe that the primary gateway will no longer accept incoming data traffic. The time delay may be based at least in part on one or more of a time interval of the periodic poll and a time to effect the gateway switchover. The forwarding of the incoming data traffic from the primary gateway to the backup gateway is terminated.

Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.
