Snapshot management in partitioned storage
The present disclosure generally relates to a storage snapshot management system. When updated data is written to the memory device, rather than rewriting all of the data, only the updated data is written to a new namespace. A snapshot of the new namespace indicates which LBAs in the new namespace contain data. New namespaces are added each time data is updated. When the updated data is to be read, the data storage device reads the updated LBA from the new namespace, and also gathers the non-updated data from the previous namespace. Eventually, the number of namespaces for the data reaches a threshold, and thus some namespaces need to be evicted. To evict a namespace, the updated data in the namespace is moved to a different namespace, or the non-updated data is moved to a namespace that contains updated data. In either case, the now unused namespaces are evicted. |

A method of deploying a virtual network function of a network service in a data center having a cloud management server running a cloud computing management software to provision virtual infrastructure resources of the data center to at least one tenant, includes generating at least first and second API calls to the cloud computing management software in response to external commands received at the data center to deploy a virtual network function, and executing at least the first and second API calls by the cloud computing management software to deploy the virtual network function. The cloud computing management software creates at least one virtual machine by executing the first API call and at least one virtual disk by executing the second API call. |

System reset using a controller
In some examples, a storage medium stores information relating to reset ports associated with respective virtual machines (VMs) of a plurality of VMs. A controller detects, based on the information, an activation of a first reset port associated with a first VM of the plurality of VMs. In response to the detecting, the controller provides an indication of the activation of the first reset port to a hypervisor that is separate from the controller, the indication to cause the hypervisor to reset the first VM. |

Providing non-volatile storage for permanent data to virtual machines
One or more aspects of the present disclosure relate to allocating virtual memory to one or more virtual machines (VMs). The one or more VMs can be established by a hypervisor of a storage device. The virtual memory can be allocated to the established one or more VMs. The virtual memory can correspond to non-volatile (NV) memory of a global memory of the storage device. |

Processor virtualization in unmanned vehicles
A processing system for an unmanned vehicle (UV) such as an unmanned aerial vehicle (UAV) is provided. The processing system comprises a first processing unit of an integrated circuit and a second processing unit of the integrated circuit. The processing system comprises a first operating system provisioned using the first processing unit. The first operating system is configured to execute a first vehicle control process. The processing system comprises a virtualization layer configured using at least the second processing unit, and a second operating system provisioned using the virtualization layer. The second operating system is configured to execute a second vehicle control process. |

Process initiation
Implementations generally relate to initiating processes. In some implementations, a method includes receiving, at a server, an object from a client device. The method further includes determining an instance of a process initiation event, where the process initiation event triggers a process to initiate, and where the process initiation event is based on the object and one or more process initiation policies. The method further includes initiating the process upon the determining of the process initiation event. |

System and method for the administration of imaging devices
In a system for the administration of a group of imaging devices which are equipped with a corresponding device hosts, device software and a configuration protocol are executably stored on the device host. The system can include a distributed database system which configured to receive configuration protocols from the device host and to store modified configuration protocols for the respective device host, and to distribute modified configuration protocols. The received and/or stored configuration protocols are made available via a central write access. The system can include an administrator having a memory, a user interface and a processor for communicating with the distributed database system. Configuration protocols can be modified via the user interface and sent to the distributed database system for storage and/or distribution to at least one selected imaging device. These aspects are also applicable to a method for the administration of imaging devices. |

Duplicate detection for register renaming
Systems and methods are disclosed for duplicate detection for register renaming. For example, a method includes checking a map table for duplicates of a first physical register, wherein the map table stores entries that each map an architectural register of an instruction set architecture to a physical register of a microarchitecture and a duplicate is two or more architectural registers that are mapped to a same physical register; and, responsive to a duplicate of the first physical register in the map table, preventing the first physical register from being added to a free list upon retirement of an instruction that renames an architectural register that was previously mapped to the first physical register to a different physical register, wherein the free list stores entries that indicate which physical registers are available for renaming. |

Byte comparison method for string processing and instruction processing apparatus
Embodiments of the present disclosure provide an instruction processing apparatus, comprising a first register configured to store a source string, wherein the source string comprises at least one byte, and an execution circuitry, communicatively coupled to the first register and configured to execute a comparison instruction to compare the at least one byte in the source string with an ending identifier to obtain a result value corresponding to the source string, wherein the comparison instruction is executed on each of the at least one byte in the source string and the comparison instruction is an assembly code instruction. |
