摘要:
A method and system for an infrastructure for performance-based chip-to-chip stacking are provided in the illustrative embodiments. A critical path monitor circuit (infrastructure) is configured to launch a signal from a launch point in a first layer, the first layer being a first circuit. The infrastructure is further configured to create an electrical path to a capture point. The signal is launched from the launch point in the first layer. A performance characteristic of the electrical path is measured, resulting in a measurement, wherein the measurement is indicative of a performance of the first layer when stacked with a second layer in a 3D stack without actually stacking the first and the second layers in the 3D stack, the second layer being a second circuit.

A method, system, and computer program product for performance-based chip-to-chip stacking are provided in the illustrative embodiments. A first candidate chip is selected from a set of candidate chips for stacking, each candidate chip in the set of candidate chips including an integrated circuit. A part of a 3D performance determinant is activated in the first candidate chip. A value of a performance parameter is measured for a set of operating conditions. A stacked performance value is computed for the first candidate chip using the value. A subset of the set of candidate chips is stacked in a stack, the subset including the first candidate chip, such that a combined value of the performance parameter for the subset when stacked in a first order is within a defined range of values for the performance parameter.

Enhanced modularity in heterogeneous three-dimensional computer processing chip stacks includes a method of manufacture. The method includes preparing a host layer and integrating the host layer with at least one other layer in the stack. The host layer is prepared by forming cavities on the host layer for receiving chips pre-configured with heterogeneous properties relative to each other, disposing the chips in corresponding cavities on the host layer, and joining the chips to respective surfaces of the cavities thereby forming an element having a smooth surface with respect to the host layer and the chips.

A computer-implemented method, system, and article of manufacture for optimizing heat transfer in a 3-D chip-stack. The method includes the steps of: receiving a heat-removal effectiveness parameter for a plurality of channel-region areas in the chip-stack, receiving at least one of a flow value and temperature value for at least two of the channel-region areas, comparing the received values for different channel-region areas, and adjusting a flow rate of a liquid flowing to at least one of the two channel-region areas based on the heat-removal effectiveness parameter of the channel-region area receiving the adjustment and the results of the comparison step, where at least one step is carried out using a computer device.

A processor-implemented method for improving efficiency of a static core turn-off in a multi-core processor with variation, the method comprising: conducting via a simulation a turn-off analysis of the multi-core processor at the multi-core processor's design stage, wherein the turn-off analysis of the multi-core processor at the multi-core processor's design stage includes a first output corresponding to a first multi-core processor core to turn off; conducting a turn-off analysis of the multi-core processor at the multi-core processor's testing stage, wherein the turn-off analysis of the multi-core processor at the multi-core processor's testing stage includes a second output corresponding to a second multi-core processor core to turn off; comparing the first output and the second output to determine if the first output is referring to the same core to turn off as the second output; outputting a third output corresponding to the first multi-core processor core if the first output and the second output are both referring to the same core to turn off.
摘要:
A three-dimensional computer processing chip stack that includes a host layer disposed on at least one other layer in the stack. The host layer includes cavities formed thereon for receiving chips pre-configured with heterogeneous properties relative to each other. The cavities are formed to accommodate the heterogeneous properties of the chips. The chips are joined to respective surfaces of the cavities, thereby forming an element having a smooth surface with respect to the host layer and the chips.

A system to improve operation of a data center with heterogeneous computing clouds may include monitoring components to track data center climate controls and individual heterogeneous computing clouds' operating parameters within the data center. The system may also include a controller that regulates the individual heterogeneous computing clouds and data center climate controls based upon data generated by the monitoring components to improve the operating performance of the individual heterogeneous computing clouds as well as the operating performance of the data center. The system may further include spilling computing clouds to receive excess workload of an individual heterogeneous computing cloud without violating individual heterogeneous computing clouds contracts.
摘要:
A mechanism is provided for minimizing reliability problems in a three-dimensional (3D)) integrated circuit. A set of sensors are interrogated for current data. A direction of force and a magnitude of the force are determined based on the current data for each sensor in the set of sensors for each of one or more directions between the sensor and at least one neighboring sensor thereby forming a set of forces. Each of the set of forces is used to identify one or more points of stress that are at or above the predetermined force threshold. Responsive to identifying at least one point of stress that is at or above the predetermined force threshold, one or more temperature actuation actions are initiated in order to reduce at least one point of stress in the region where the at least one point of stress is identified.
