A method, system and memory controller are provided for implementing signal integrity fail recovery and mainline calibration for Dynamic Random Access Memory (DRAM). After identifying a failed DRAM, the DRAM is marked as bad and taken out of mainline operation. Characterization tests and periodic calibrations are run to evaluate optimal settings and to determine if the marked DRAM is recoverable. If recoverable, the marked DRAM chip is redeployed. If unrecoverable, error reporting is provided to the user.

A fault-tolerant distributed real-time computer system for controlling a physical system, in particular a machine or a motor vehicle, wherein the components of the computer system have access to a global time of known precision, and wherein the node computers and intelligent sensors and the intelligent actuators exchange time-triggered messages and event-triggered messages periodically via the distributor units, and wherein the functions of the user software are contained in real-time software components—RTSC—and the periodic time-triggered data transfer between the RTSC is specified by a time-triggered data flow diagram, and wherein the assignment of the RTSC to a TTVM of a node computer and specific parameters of the TTVM are contained in active local allocation plans for each RTSC, and wherein the time plans for the time-triggered communication in this distributor unit are contained in active local allocation plans for each distributor unit, and wherein a global allocation plan consists of the totality of the local allocation plans, which are adapted to one another, of all RTSC and all distributor units of the user software, and wherein a monitor component periodically receives a copy of messages of the node computers to define the present operating state of the node computers, and wherein after the permanent failure of one or more RTSC, the monitor component activates a passive global allocation plan which specifies the allocation of the RTSC and the data supply thereof on newly installed TTVMs to the still functional node computers, and wherein the RTSC arrive at the newly configured TTVMs for execution at the provided periodic restart point in time in accordance with the selected passive global allocation plan.

A method includes monitoring write processing performance while storing a plurality of sets of encoded data slices in storage units. The method includes comparing the write processing performance with a desire write performance range. When the write processing performance compares unfavorably to the desire write performance range, the method includes establishing a data partition between the data segments of the data encoded using the first dispersed storage error encoding parameters and subsequent data segments of the data; determining second dispersed storage error encoding parameters based on the unfavorable comparison between the write processing performance and the desired write performance range; encoding the subsequent data segments of the data using the second dispersed storage error encoding parameters to produce a second plurality of sets of encoded data slices; and monitoring write processing performance while storing the second plurality of sets of encoded data slices in the storage units.

A device, system, and/or method includes an internal circuit configured to perform at least one function, an input-output terminal set and a repair circuit. The input-output terminal set includes a plurality of normal input-output terminals connected to an external device via a plurality of normal signal paths and at least one repair input-output terminal selectively connected to the external device via at least one repair signal path. The repair circuit repairs at least one failed signal path included in the normal signal paths based on a mode signal and fail information signal, where the mode signal represents whether to use the repair signal path and the fail information signal represents fail information on the normal signal paths. Using the repair circuit, various systems adopting different repair schemes may be repaired and cost of designing and manufacturing the various systems may be reduced.

A memory system includes a plurality of volatile memory modules to temporarily store data in a distributed manner, a V storing place management unit included in each of the volatile memory modules, a plurality of nonvolatile memory modules to store the data stored in each of the volatile memory modules in a distributed manner, and a NV storing place management unit included in each of the nonvolatile memory modules. Each V storing place management unit and each NV storing place management unit communicate and determine the destination nonvolatile memory module for each volatile memory module. The data is transmitted to the determined destination nonvolatile memory module and stored in the destination nonvolatile memory module.

This application discloses a processing node management method and apparatus, a device, and a storage medium, which belongs to the field of cloud technologies and big data. The method includes: obtaining, in response to an abnormal processing node in a processing node cluster being detected, abnormal status information of the abnormal processing node; in response to the abnormal status information satisfying a condition, enabling an auxiliary node outside the processing node cluster to replace the abnormal processing node; adjusting an execution policy of the data processing task in response to the auxiliary node being enabled; distributing data processing sub-tasks to the auxiliary node and remaining processing nodes based on the execution policy; and transmitting corresponding task execution instructions to the auxiliary node and the remaining processing nodes, the task execution instructions being used for instructing the auxiliary node and the remaining processing nodes to perform the corresponding data processing sub-tasks.

A method, apparatus, and system are directed toward configuring a dependency relationship between resources in a cluster. A dependency relationship between a dependent in a first resource group and a dependee in a second resource group is declared. The dependency relationship might include a locality based qualifier and/or a time based qualifier. The locality based qualifier includes a Local Node, Any Node, or From Resource Group Affinity relationship. The time based dependency qualifier includes a Strong dependency, Weak dependency, Online Restart dependency, or Offline Restart dependency. The declaration might be made using a graphical user interface, property list, configuration file, or the like. A candidate node on which to activate the first resource group is determined. The dependent is brought online on the candidate node based on whether an instance of the dependee is online on a node specified by the locality based qualifier.

Techniques for reconfiguring a snapshot of a virtual machine (VM) may be provided. The VM may be deployed on a hypervisor running on a computer. Techniques comprise provisioning of a VM, installing and configuring an operating system and a base program. A snapshot of the virtual machine may be taken together with the operating system and the base program together with configuration data defining the configuration of the virtual machine, the operating system and base application in a metadata descriptor. All may be stored in a persistent storage. Then the content of the metadata descriptor may be modified, and it may be reverted back to the snapshot using the modified content of the metadata descriptor such that the snapshot of the virtual machine with the operating system and the base program is reconfigured upon deployment of the snapshot including the operating system and the base program.

Aspects extend to methods, systems, and computer program products for (re)configuring acceleration components over a network. (Re)configuration can be implemented for any of a variety of reasons, including to address an error in functionality at the acceleration component or to update functionality at the acceleration component. During (re)configuration, connectivity can be maintained for any other functionality at the acceleration component untouched by the (re)configuration. Network (re)configuration of acceleration components facilitates management of acceleration components and accelerated services from a centralized service. Network (re)configuration of acceleration components also relieves host components from having to store (potentially diverse and numerous) image files.
