Abstract: The disclosed technology provides techniques, systems, and apparatus for containing and recovering from uncorrectable memory errors in distributed computing environment. An aspect of the disclosed technology includes a hypervisor or virtual machine manager that receives signaling of an uncorrectable memory error detected by a host machine. The virtual machine manager then uses information received via the signaling to identify virtual memory addresses or memory pages associated with the corrupted memory element so as to allow for containment and recovery from the error.

Abstract: A combined data processing unit (DPU) and server solution with DPU operating system (OS) integration is described. A DPU OS is executed on a DPU or other computing device, where the DPU OS exercises secure calls provided by a DPU's trusted firmware component, that may be invoked by DPU OS components to abstract DPU vendor-specific and server vendor-specific integration details. An invocation of one of the secure calls made on the DPU to communicate with its associated server computing device is identified. In an instance in which the one of the secure calls is invoked, the secure call invoked is translated into a call or request specific to an architecture of the server computing device and the call is performed, which may include sending a signal to the server computing device in a format interpretable by the server computing device.

Abstract: An automated toolset performs configuration conflict resolution for virtual machines (VMs) providing services in a networked cloud computing system by determining a set of changes to be committed through a series of automated actions. The toolset resolves conflicts among multiple possible configurations that could result in an incorrect VM state and merges configurations in view of inputs from internal and external systems. The toolset operates to identify only a subset of changes that differ between current and new configurations that are loaded into the system to streamline configuration loading and provide for lightweight restoration by rolling back only those differences. Further efficiencies are achieved using an automated test suite environment that is specially adapted to test and validate new configurations to ensure correct loading and avoid system failures.

Abstract: System and method for managing distributed storage objects for host unavailability in a distributed storage system uses at least one of a crash indicator in a specific on-disk block and a paused object indicator for a distributed storage object to determine whether to perform data recovery for the distributed storage object. When the crash indicator is set or the paused object indicator implies that the distributed storage object is a paused object, the distributed storage object is left as a paused object without perform the data recovery for the distributed storage object. When the crash indicator is unset and the paused object indicator implies that the distributed storage object is not a paused object, the data recovery for the distributed storage object is performed.

Abstract: Methods, systems, and devices for scrub operations with row error information are described. A memory device may include a memory array with a set of rows. During a scrub operation, the memory device may read data and error control information stored in a row of the memory array and detect a quantity of errors in the row. The memory device may store the quantity of detected errors in the row of the memory device during the scrub operation in memory cells of the memory array storing data associated with the row of the memory array. In some cases, the memory device may then determine that the row is associated with a decreased reliability based on the stored quantity of errors detected in the row during the scrub operation. Here, the memory device may reconfigure the memory array to store the data of the row in another row.

Abstract: First firmware metadata and second firmware metadata are based on nonvolatile metadata stored in the nonvolatile memory device. A normal operation including a first management operation resulting in a change of the first firmware metadata and an access operation in which the nonvolatile memory device is accessed may be performed. A virtual operation is performed including a second management operation resulting in a change of the second firmware metadata and in which the access operation is not performed. Whether an error has occurred in the first firmware metadata is determined by comparing the change of the first firmware metadata resulting from the first management operation and the change of the second firmware metadata resulting from the second management operation. An error in the metadata may be monitored through the redundant performance of the management operation that results in the change of the metadata without a corresponding access to the nonvolatile memory device.

Abstract: Methods, systems, and apparatuses related to a memory fault map for an accelerated neural network. An artificial neural network can be accelerated by operating memory outside of the memory's baseline operating parameters. Doing so, however, often increases the amount of faulty data locations in the memory. Through creation and use of the disclosed fault map, however, artificial neural networks can be trained more quickly and using less bandwidth, which reduces the neural networks' sensitivity to these additional faulty data locations. Hardening a neural network to these memory faults allows the neural network to operate effectively even when using memory outside of that memory's baseline operating parameters.

Configurations for a plurality of different data management services are automatically determined in an attempt to achieve the specified data protection intent. The determined configurations in the plurality of different data management services are automatically implemented.

Abstract: A test stimulus generator generates error irritations, or error sequences, within a processor system. The test stimulus generator includes an initialization register, a pseudo-random number generator (PRNG), a clock subsystem, and an output register. The PRNG calculates an output value from an initialization value stored in the initialization register. The PRNG output value represents a unique error irritation and identifies one or more components within the processor system to handle the error irritation. The clock subsystem generates either a continuous or pulsed clock signal that transfers the initialization value into the PRNG. The output register stores the PRNG output value and transmits the corresponding error irritation to the processor components identified to handle the error irritation. The test stimulus generator generates error irritations in a predetermined or random order based on the initialization value. A corresponding method and computer program product are also disclosed.

Abstract: A hardware-assisted paravirtualized hardware watchdog is described that is used to detect and recover from computer malfunctions. A computing device determines that a hardware-implemented watchdog of the computing device does not comply with predetermined watchdog criteria, where the hardware-implemented watchdog is configured to send a reset signal when a first predetermined amount of time elapses without receipt of a first refresh signal. If the hardware-implemented watchdog does not comply with the predetermined watchdog criteria, a runtime watchdog service is initialized using a second predetermined amount of time. The runtime watchdog service is directed to periodically send the refresh signal to the hardware-implemented watchdog before an expiration of the first predetermined amount of time that causes the hardware-implemented watchdog to expire.

Abstract: A method of monitoring execution of computer instructions includes receiving data items representing real-time measurements of side-channel information emanating from execution of computer instructions, each data item forming a value of a corresponding dimension of a side-channel information vector, receiving, for two or more of the dimensions of the side-channel vector, classifiers that assign the corresponding values of a side-channel vector to classes, and classifying the data items in accordance with the received classifiers, wherein an orthogonal distance of the data item from the classifier indicates a confidence value of the classification, generating a combined a confidence value for the side-channel information vector a, and outputting a signal if a confidence value indicates affiliation to a selected one of the two classes with a predetermined probability. The method conducts a self-test by generating a combined confidence value based to ensure correct outputting of the confidence value.
