Abstract: A 4D device comprises a 2D multi-core logic and a 3D memory stack connected through the memory stack sidewall using a fine pitch T&J connection. The 3D memory in the stack is thinned from the original wafer thickness to no remaining Si. A tongue and groove device at the memory wafer top and bottom surfaces allows an accurate stack alignment. The memory stack also has micro-channels on the backside to allow fluid cooling. The memory stack is further diced at the fixed clock-cycle distance and is flipped on its side and re-assembled on to a template into a pseudo-wafer format. The top side wall of the assembly is polished and built with BEOL to fan-out and use the T&J fine pitch connection to join to the 2D logic wafer. The other side of the memory stack is polished, fanned-out, and bumped with C4 solder. The invention also comprises a process for manufacturing the device.

Abstract: A mechanism is provided for delivering troubleshooting support that captures a user's interactions with a local computing device. Responsive to receiving a set of events associated with an issue being experienced by the user of the local computing device, each event in the set of events is presented to a technician. Each event in the set of events is flagged as either correct or incorrect. Responsive to the incorrect flagged event being an operation performed by the local computing device, a communicative connecting is established to the local computing device in order that the technician corrects a future operation corresponding to the operation performed. Responsive to the incorrect flagged event being an action performed by the user of the local computing device, an analysis is sent in order to inform the user of incorrect actions so as to not perform the incorrect actions in the future.

Abstract: A method for data mining on compressed data vectors by a certain metric being expressible as a function of the Euclidean distance is suggested. In a first step, for each compressed data vector, positions and values of such coefficients having the largest energy in the compressed data vector are stored. In a second step, for each compressed data vector, the coefficients having not the largest energy in the compressed data vector are discarded. In a third step, for each compressed data vector, a compression error is determined in dependence on the discarded coefficients in the compressed data vector. In a fourth step, at least one of an upper and a lower bound for the certain metric is retrieved in dependence on the stored positions and the stored values of the coefficients having the largest energy and the determined compression errors.

Abstract: A method and/or computer program product identifies and/or predicts a cognitive state of a user. A buffer on a device is loaded with a predetermined set of sensor readings for a user. A hardware receiver receives a “push” signal from the device. The “push” signal is transmitted by the user in response to the user subjectively experiencing a user-defined cognitive state. The “push” signal causes readings from the buffer to be loaded as pushed sensor readings onto a data matrix. One or more processors analyze the pushed sensor readings to identify a sensor pattern of the pushed sensor readings. In response to detecting a subsequent set of sensor readings that match the sensor pattern of the pushed sensor readings, a signal transmitter transmits a cognitive state signal that indicates a prediction of a particular cognitive state of the user.

Abstract: A mechanism is provided in a data processing system comprising a processor and a memory, the memory comprising instructions that are executed by the processor to specifically configure the processor to implement an initiator entity in a symmetric split-direction connection. The initiator entity generates a custom keepalive command and sends the custom keepalive command to a target entity via the symmetric split-direction connection. Responsive to the initiator entity determining a number of consecutive acknowledgement commands received in response to custom keepalive commands exceed a first threshold, the initiator entity reports the symmetric split-direction connection as sufficient. Responsive to the initiator entity determining a second number of consecutive keepalive commands sent without receiving an acknowledgement is greater than a second threshold, the initiator entity reports the symmetric split-direction connection as insufficient.

Abstract: In managing the backlog of undelivered publications for durable subscriptions, a maximum quantity of publications stored in connection with a durable subscription to publications of a particular topic can be established on behalf of a particular subscribing end user. A new publication published for the particular topic subscribed to by the end user can be received and it can be determined if storing the new publication in connection with the durable subscription causes a quantity of publications stored in connection with the durable subscription to exceed the maximum quantity. The new publication can be stored in connection with the durable subscription; however, the oldest publication stored in connection with the durable subscription can be removed when it is determined that storing the new publication in connection with the durable subscription causes a quantity of publications stored in connection with the durable subscription to exceed the maximum quantity.
