摘要： A system and method tests computer software using tracking bits in branch instructions to track portions of the software that have been tested. The tracking bits are bits of a branch programming instruction and may be repurposed hint bits used in the prior art to control pre-fetch of instructions. A branch tracking unit sets bits in a branch instruction of an application or program being tested. The branch tracing unit sets a first bit if a branch is taken and sets a second tracking bit if the branch is not taken. The modified program instructions can be analyzed after running the test inputs to determine if any branches in the software have not been exercised by the test inputs.

摘要： Technical solutions are described for generating a secured system snapshot of a system. An example computer-implemented method includes receiving an instruction to generate a system snapshot. The system snapshot captures data from a computer executable object loaded in a memory. The method also includes accessing metadata that is associated with the computer executable object from a mapping list. The method also includes capturing the secured system snapshot by. Capturing the secured system snapshot includes determining sensitivity of the computer executable object by comparing the metadata with a predetermined criteria, and excluding a capture of sensitive data from the computer executable object into the system snapshot in response to the metadata of the computer executable object matching the predetermined criteria. The method also includes storing the secured system snapshot.

摘要： A method for preventing photographic capture of a displayed image on an electronically controlled screen using a photographic capture device is provided. The method includes intercepting an image for display; generating a plurality of subset frames based on the intercepted image; dividing the intercepted image into a plurality of subsections; generating a pseudo random number on each of the subsections within the plurality of subsections using a pseudo random number generator; mapping, on each of the subset frames within the plurality of subset frames, a group of subsections within the plurality of subsections that share a common generated pseudo random number; determining a frame rate value for displaying the plurality of subset frames, which enables human visualization of the plurality of subset frames as a single perceived frame; and displaying each subset frame consecutively on the electronically controlled screen based on the determined frame rate.

摘要： A computer system is monitored for conditions bearing on the effective age of various hardware components of the system. Upon detecting an age adjustment condition, the affected hardware components are identified. An age adjustment is determined for each of the affected hardware components. The adjusted age is stored for reference when taking actions based on the adjusted age, such a component replacement and/or workload placement.

摘要： A method, system and computer-usable medium are disclosed for persisting Lightweight Memory Trace (LMT) data across reboots of a system. One or more LMT traces are stored in a predetermined pinned memory area with a server's operating system (OS) through a system reboot. A pointer to each LMT is likewise stored in nonvolatile storage (NVS) at a known memory location. The pointers in NVS point to a page which describes where the LMT trace and other kernel structures are in real memory. During initialization, the OS guards these preserved pages to prevent them from being used. By keeping the current and prior address within NVS, the current LMT and prior traces can be retrieved and processed to determine the cause of the system reboot.
