    摘要: Techniques for management of virtual representations (e.g., digital twins) of infrastructure are disclosed. For example, a method comprises obtaining at least one virtual representation of an infrastructure, wherein the virtual representation represents the infrastructure in a first state. The method further comprises applying at least one dataset to the virtual representation to artificially advance the virtual representation to represent the infrastructure in a second state. The method further comprises obtaining results representing the infrastructure in the second state, responsive to applying the at least one dataset to the virtual representation, wherein at least a portion of the results are indicative of an issue with the infrastructure, and then initiating one or more debugging actions with respect to the infrastructure to address the issue.

    摘要: In one example, a method of data restore testing is disclosed. The method may determine whether to validate a request to restore a backup of production data. The request may be for a database backup, a file system backup or another data type. The method may generate a database instance that restores a backup database data if the request is for database data and may generate a file system instance to restore a backup file system if the request is for a backup of a file system. The method may lockdown access to the restored backup, validate the integrity of the restored backup relative to production data. The validation may be based on a checksum of the restored backup and a checksum of the production data, for example.

    摘要: A system performs group testing on a population of items. The group testing identifies items satisfying particular criteria from a population of items, for example, defective items from the population. The group testing may be performed for software or hardware testing, for testing a human population, for training of deep learning applications, and so on. The system trains a machine learning based model, for example, a reinforcement learning based model to evaluate groups. The model may further determine system dynamics that may represent priors of items. An agent treats the population and groups of items being tested as the environment and performs actions, for example, adjusting the groups. The system also performs a non-adaptive strategy based on monte carlo simulation of tests based on a simulation results.

    摘要: Provided is a method for performing an aging test on a neural processing unit (NPU) with a capability of a runtime test. The method may comprise: performing an aging test on the NPU which comprises a plurality of functional components. The plurality of functional components may comprise at least one memory and plural processing elements. The performing of the aging test may include: performing a scan test on the NPU to verify whether at least one functional component in the NPU is defective or not; and performing a memory test on the at least one memory. At least one of the scan test and the memory test may be repeatedly performed to put a stress on the NPU for the aging test. The aging test may be repeated by a predetermined number.

    摘要: One example method occurs at an impairment configuration manager of a network test system implemented using at least one processor, the method comprising: receiving impairment definition information for defining one or more impairments associated with a test session involving a test infrastructure connecting at least one test application and a system under test (SUT), wherein the impairment definition information includes information for indicating attributes of the one or more impairments using a common data model or data format; generating, using the impairment definition information, at least one set of instructions for configuring at least one impairment element to implement the one or more impairments during the test session; and providing the at least one set of instructions to the at least one impairment element or another entity.
