  • Dynamic write-back to non-volatile memory
    Patent number: 11163680
    Abstract: Embodiments of the present invention include receiving, by an operating system, a request from an application to reserve a subset of a memory allocated to the application for mirroring. The request specifies a size of the subset. A first portion of the specified size and a second portion of the specified size of the memory are reserved by the operating system for the mirroring. Data to write to the first portion of the memory is received from the application. The operating system writes the data to the first portion of the memory and initiates a background write-back process of the data to the second portion of the memory.
    Type: Grant

  • Securing external communication ports in automated teller machines
    Patent number: 11151847
    Abstract: Embodiments of the present invention provide a computer system, a computer program product, and a method that comprises identifying at least a first physical sensor and a second physical sensor within a computing device, wherein each physical sensor is associated with a respective count; performing a predetermined operation within the computing device; authenticating the received command of at least the first physical sensor and the second physical sensor identified within the computing device; and automatically halting the operation of the computing device.

  • Filesystem using hardware transactional memory on non-volatile dual in-line memory module
    Patent number: 11126459
    Abstract: A computer-implemented method comprises receiving a request to write to a file and, in response to the request, determining that the file exists in a storage device. In response to the determination that the file exists, the method further comprises mapping the file into a region of a non-volatile dual in-line memory module (NVDIMM); initiating a transaction to write to the mapped file in the NVDIMM without acquiring a speculative lock on the mapped file; and determining whether a conflict occurred in writing to the mapped file in the NVDIMM. In response to a determination that a conflict occurred, the method comprises restarting the transaction to write to the mapped file in the NVDIMM without acquiring the speculative lock on the mapped file. In response to a determination that no conflict occurred, the method comprises committing changes made to the mapped file to the file in the storage device.
