Abstract: Embodiments disclosed herein describe systems and methods for tuning phases of interface clocks of ASICs in an emulation system for a low latency channel and to avoid read errors. During a bring-up time (e.g., powering up) of the emulation system, one or more training processors may execute a software application to iteratively tune the phases of the interface clocks such that data is written to the interface buffers prior to being read out. To mitigate the problem of higher latency, the training processors may execute software application to tune the clock phases such that there is a small time lag between the writes and reads. The training processors may set the time lag to account for factors such as memory setup and hold, clock skews, clock jitters, and the predicted margin required to account for future clock drift due to carrying operating conditions.

Abstract: Illustrative systems and methods enable a virtual machine (“VM”) to be powered up at any hypervisor regardless of hypervisor type, based on live-mounting VM data that was originally backed up into a hypervisor-independent format by a block-level backup operation. Afterwards, the backed up VM executes anywhere anytime without needing to find a hypervisor that is the same as or compatible with the original source VM's hypervisor. The backed up VM payload data is rendered portable to any virtualized platform. Thus, a VM can be powered up at one or more test stations, data center or cloud recovery environments, and/or backup appliances, without the prior-art limitations of finding a same/compatible hypervisor for accessing and using backed up VM data. An illustrative media agent maintains cache storage that acts as a way station for data blocks retrieved from an original backup copy, and stores data blocks written by the live-mounted VM.

A triggerable fluid supply is coupled to the casing and projects fluid to a tool or a section of glass being resurfaced by the tool.

Abstract: Encryption of data occurs before it is written to the storage platform; decryption occurs after it is read from the storage platform on a computer separate from the storage platform. By encrypting data before it travels over a wide-area network to a storage platform (and by only decrypting that data once it has arrived at an enterprise from the storage platform), we address data security over the network. Application data is encrypted at the virtual disk level before it leaves a controller virtual machine, and is only decrypted at that controller virtual machine after being received from the storage platform. Encryption and decryption of data is compatible with other services of the storage system such as de-duplication. Any number of key management services can be used in a transparent manner.

Abstract: A method and system for migrating data and metadata from a first backup system to a second backup system via a content staging system is disclosed. The system accesses the backup data from the first backup system and restores it, along with the associated metadata, to a staging system. A metadata file is created at the staging system which comprises of the metadata that is to be migrated to the second backup system. The system then migrates the data from the staging system to the second backup system. The metadata is also migrated to the second backup system in a format such that it can be indexed. As a result, the migrated data can be browsed and searched based on one or more search criteria based on the associated metadata. Other details are provided herein.

Abstract: A client machine writes to and reads from a virtual disk on a remote storage platform. Metadata is generated and stored in replicas on different metadata nodes of the storage platform. A modified log-structured merge tree is used to store and compact string-sorted tables of metadata. During file storage and compaction, a consistent file identification scheme is used across all metadata nodes. A fingerprint file is calculated for each SST (metadata) file on disk that includes hash values corresponding to regions of the SST file. To synchronize, the fingerprint files of two SST files are compared, and if any hash values are missing from a fingerprint file then the key-value-timestamp triplets corresponding to these missing hash values are sent to the SST file that is missing them. The SST file is compacted with the missing triplets to create a new version of the SST file. The synchronization is bi-directional.

Abstract: Systems and methods for establishing a secure connection are described. A server receives a plurality of routing tokens for establishing a service connection between a service node and the server along a network path through a plurality of network devices. The routing tokens can be validated by a corresponding network device. The server transmits a packet including the routing tokens to a first network device. The first network device validates a first routing token associated therewith, then directs the packet along the network path to a second network device, and so forth, until each of the network device receives and validates their routing token. The server establishes a cryptographic context between the service node and server for establishing a secure channel between the service node and the server. The server transmits a service node routing token to the service node via the secure channel for validation.

Abstract: A hybrid computing system comprising a quantum computer and a digital computer employs a digital computer to use machine learning methods for post-processing samples drawn from the quantum computer. Post-processing samples can include simulating samples drawn from the quantum computer. Machine learning methods such as generative adversarial networks (GANs) and conditional GANs are applied. Samples drawn from the quantum computer can be a target distribution. A generator of a GAN generates samples based on a noise prior distribution and a discriminator of a GAN measures the distance between the target distribution and a generative distribution. A generator parameter and a discriminator parameter are respectively minimized and maximized.
