  • Patent number: 10049957
    Abstract: A method, system, and computer program product for on-chip control of thermal cycling in an integrated circuit (IC) are provided in the illustrative embodiments. A first circuit is configured on the IC for adjusting a first voltage being applied to a first part of the IC. A first temperature of the first part is measured at a first time. A determination is made that the first temperature is outside a temperature range defined by an upper temperature threshold and a lower temperature threshold. The first voltage is adjusted by reducing the first voltage when the first temperature exceeds the upper temperature threshold and by increasing the first voltage when the first temperature is below the lower temperature threshold, thereby causing the first temperature of the first part to attain a value within the temperature range.

  • Patent number: 9934079
    Abstract: A system, and computer usable program product for fast remote communication and computation between processors are provided in the illustrative embodiments. A direct core to core communication unit (DCC) is configured to operate with a first processor, the first processor being a remote processor. A memory associated with the DCC receives a set of bytes, the set of bytes being sent from a second processor. An operation specified in the set of bytes is executed at the remote processor such that the operation is invoked without causing a software thread to execute.

  • Patent number: 9473398
    Abstract: A set of routing rules is receiving at a networking device in a data communication network from a controller in the data communication network implemented using the software-defined network architecture. A condition is detected at the networking device. A subset of the set of routing rules is selected in the networking device. The selecting is responsive to the condition. The subset of routing rules is applied in the networking device at a first time such that the networking device uses a first routing rule to route data traffic in the data communication network, and omits using a second routing rule received from the controller to route data traffic in the data communication network. A second subset of routing rules from the set of routing rules responsive to a second condition is applied autonomously at a second time at the networking device.

  • Patent number: 8779846
    Abstract: A method for improving the performance of a digital circuit is provided in the illustrative embodiments. A real frequency of operation of the digital circuit is adjusted using a control loop in the digital circuit, the adjusting the real frequency being responsive to a change in an operating condition of the digital circuit. A measurement of a current drawn by the digital circuit is received from a voltage regulator supplying electrical power to the digital circuit. An over-current target current value is received. A voltage output from the voltage regulator to the digital circuit is adjusted such that the current drawn by the digital circuit does not exceed the over-current target current value.

  • Patent number: 8738875
    Abstract: A system, and computer program product for increasing a capacity of a memory are provided in the illustrative embodiments. Using an application executing using a processor wherein the memory includes a set of ranks, the memory is configured to form a cold tier and a hot tier, the cold tier including a first subset of ranks from the set of ranks in the memory, and the hot tier including a second subset of ranks from the set of ranks in the memory. A determination is made whether a page to which a memory access request is directed is located in the cold tier in the memory. In response to the page being located in the cold tier of the memory, the processing of the memory access request is throttled by processing the memory access request with a delay.

  • Publication number: 20140074960
    Abstract: A method, system, and computer program product for compacting a non-biased results multiset are provided in the illustrative embodiments. A set of references and a multiset of values are identified. The multiset includes a first and a second set of values, each set including a first value. A first reference in the set of references refers to the first set of values and a second reference in the set of references refers to the second set of values. The values in the first and second set of values are re-arranged to form permuted first and second sets of values. The multiset is compacted by overlaying the permuted first and second sets of values in a portion such that the permuted first set of values and the permuted second set of values share a single instance of the first value in a portion of the compacted multiset.
