Abstract: As disclosed herein a method, executed by a processor, for accelerated instruction execution includes retrieving an execute instruction including a register reference and a reference to a target instruction, retrieving the target instruction, decoding the execute instruction using an instruction pipeline, decoding the target instruction using the instruction pipeline, associating the register reference to the target instruction, and executing the target instruction using the register reference as a source operand modifier. The instruction pipeline is configured such that it allows the target instruction to continue processing without waiting for the register reference to be resolved. The contents of the referenced register may be retrieved in a later stage of the instruction pipeline, and the target instruction may be modified and executed. An apparatus corresponding to the described method is also disclosed herein.

Abstract: An improved white cane includes an elongate body having a proximal end adapted to be held by or secured to a human user and a distal tip, and a noise generator located proximate the distal tip, the noise generator being configured to generate sound within a range of frequencies audible to humans. The user is able to interpret differences in reflected sound as the white cane is moved about the user's surroundings to obtain more information about the surroundings than could be obtained using a normal white cane. Additionally, the information about the surroundings may become available to the user before that information might otherwise have been available to the user using a standard white cane.

Abstract: Some embodiments relate to apparatus for enhancing vehicle performance along an inclined surface. The apparatus can include a brake modulator that is controllable to reduce or limit the vehicle speed. A controller can control the brake modulator to selectively operate in a hill start assist mode. In the hill start assist mode, the controller can control the brake modulator to hold the vehicle stationary after the vehicle is initially stopped while traveling along the inclined surface, until an acceleration input member is manually operated to control a power source to propel the vehicle. The controller can control the brake modulator to release fluid pressure at the friction members at a pressure release rate that is based on a current position of the acceleration input member.

Abstract: A load request is received to retrieve a piece of data from a location in memory and the load request follows one or more store requests in a set of instructions to store a piece of data in the location in memory. One or more possible locations in a cache for a piece of data corresponding to the location in memory is determined. Each possible location of the one or more possible locations in the cache is determined. It is then determined if at least one location of the one or more possible locations contains data to be stored in the location in memory. Data in one location of the at least one location is loaded, the data in the one location is from a store request of the one or more store requests and the store request is closest in the set of instructions to the load request.

Abstract: Technical solutions are described for authenticating a hosting system prior to securely deploying a shrouded virtual server. An example method includes receiving, by a hypervisor, a request for a public certificate, from a client device that requested the virtual server, and sending the public certificate of the hosting system that executes the hypervisor. The method also includes receiving, in response to the public certificate being successfully authenticated by the client device using a third-party verification system, a session key based on a public key included in the public certificate. The method also includes decrypting the session key using a private key, where the private key is pre-installed in the hosting system by a manufacturer of the hosting system, and sending an acknowledgement message encrypted using the session key. The method also includes establishing a secure communication between the client device and the hypervisor using the session key.

Abstract: In one embodiment, a computer-implemented method includes requesting, by a first processor thread of a computer processor, access to exception tracking logic. The exception tracking logic is accessible by a plurality of processor threads. The first processor thread receives access to the exception tracking logic. The first processor thread executes a process in slow mode. Based on detecting an exception in slow mode, the first processor thread stores, in the exception tracking logic, exception information about the exception. The exception information is copied from the exception tracking logic to a set of external registers outside the exception tracking logic. The exception tracking logic is released to allow access to the exception tracking logic by other processor threads of the plurality of processor threads.

Abstract: Embodiments relate to load queue entry reuse for operand store compare (OSC) history table update. An aspect includes allocating a load queue entry in a load queue to a load instruction that is issued into an instruction pipeline, the load queue entry comprising a valid tag that is set and a keep tag that is unset. Another aspect includes based on the flushing of the load instruction, unsetting the valid tag and setting the keep tag. Another aspect includes reissuing the load instruction into the instruction pipeline. Another aspect includes based on determining that the allocated load queue entry corresponds to the reissued load instruction, setting the valid tag and leaving the keep tag set. Another aspect includes based on completing the reissued load instruction, and based on the valid tag and the keep tag being set, updating the OSC history table corresponding to the load instruction.

Abstract: A system and method for providing chronic obstructive pulmonary disease (COPD) exacerbation risk notifications in real time or near-real time is described. Rescue and controller medication events are detected by sensors associated with the patient's medicament device/s, and provide a basis to determine to rescue and controller medication use trends for the patient. This data is analyzed to determine the patient's risk for COPD exacerbation after each event, and is used to send notifications to one or both of the patient and their health care provider.

Abstract: Technical solutions are described for dynamically managing an operand-store-compare (OSC) prediction table for load and store operations executed out-of-order. One general aspect includes a method that includes receiving a request to retire a queue entry corresponding to an instruction. The method also includes identifying an OSC prediction for the instruction based on an OSC prediction table entry, where the OSC prediction indicates if the instruction is predicted to hit an OSC hazard. The method also includes determining if the instruction hit the OSC hazard. The method also includes in response to the OSC prediction indicating that the instruction is predicted to hit the OSC hazard and the instruction not hitting the OSC hazard, invalidating the OSC prediction table entry corresponding to the instruction. The present document further describes examples of other aspects such as methods, computer products.
