Abstract: In a virtual machine system, an arrangement of virtual machines, which has fault tolerance, is performed. A virtual machine managing apparatus includes a similar group generating unit and an arrangement restriction generating unit. The similar group generating unit generates a group of virtual machines having a similarity relationship which indicates that performance values of virtual machines at each timing are approximately the same, out of plural virtual machines. The arrangement restriction generating unit outputs the group of virtual machines having the similarity relationship as a distributed-arrangement restriction indicating a group of virtual machines to be arranged on different processing apparatuses among plural processing apparatuses carrying out processes of the virtual machines.

Abstract: A method or network system able to efficiently redistribute information, data, and/or context between virtual machines (“VMs”) using an in-memory file system (“IMFS”) is disclosed. After requesting memory access by an application program, a process of VM using IMFS is able to forward the memory allocation request from a VM kernel operating under a VM environment to an emulator. The emulator, which operates between the VM kernel and the hypervisor, again redirects the memory allocation request to the hypervisor for storage allocation. The hypervisor subsequently allocates at least a portion of storage space in the IMFS in accordance with the memory allocation request.

Abstract: A data processing system includes a first virtual machine, a second virtual machine, a switching unit, an external data processing device, and a video output unit. The first virtual machine performs video processing on input processing data. The second virtual machine transmits/receives the processing data to/from an outside. The switching unit switches an input destination of the processing data from the first virtual machine to the second virtual machine. The external data processing device receives the processing data transmitted from the second virtual machine, performs the video processing on the processing data, and transmits the processing data to the second virtual machine. The video output unit outputs, to a video output device, the processing data on which the video processing has been performed by the first virtual machine, and outputs, to the video output device, the processing data that the second virtual machine has received.

Abstract: A system and methods are disclosed for employing firmware metadata and migrating firmware in virtualized environments. In accordance with one example, a hypervisor that is executed by a computer system obtains an address of a firmware program stored in a non-volatile memory of the computer system. The hypervisor also obtains metadata that specifies a set of capabilities of the firmware program, where the metadata is not accessible to any virtual machine hosted by the computer system.

Abstract: A first and second data handling systems provides for shared resources in a docked mobile environment. The first data handling system maintains a set of execution tasks within the first data handling system having a system dock interface to physically couple to the second data handling system. The first data handling system assigns a task to be executed by the second data handling system while the two systems are physically coupled.

The described method further comprises detecting a physical decoupling of the first and second data handling systems and displaying an execution result of the task via a first display element of the first data handling system in response to such a detection.

Abstract: A computer system may receive two or more messages. Each message may be sent by a user of one of a plurality of virtual machines that are executing on a host machine. Each message may request an adjustment of resource entitlements for the virtual machine. The computer system may aggregate the two or more messages. The computer system may determine whether a particular resource template type associated with at least one of the two or messages should be adjusted based on the aggregated messages.

Abstract: In an example embodiment, a request for an enqueue lock for a first piece of data is received from a client application. At an enqueue server separate from an application server instance, a light-weight enqueue session is then created, including generating a light-weight enqueue session identification for the light-weight enqueue session. An enqueue lock for the first piece of data is stored in the light-weight enqueue session. The light-weight enqueue session identification is then sent to the client application. In response to a detection that a session between the client application and the application server instance has been terminated, all enqueue locks in the light-weight enqueue session are deleted and the light-weight enqueue session is deleted.

Abstract: An approach is provided for controlling a task. A change ticket is received. A task to perform the change ticket is correlated with command(s) to perform the task, user(s) who are authorized to initiate execution of the command(s), and an authorized location to initiate the execution of the command(s). A request is made by a requestor to execute one of the command(s). It is determined whether (a) the requestor is currently located at the authorized location correlated with the task and (b) the requestor is one of the user(s) correlated with the task. Based in part on (a) and (b) being true, the requested command is executed. If (a) or (b) is false, then execution of the requested command is prevented.

Abstract: An apparatus and a job scheduling method are provided. For example, the apparatus is a multi-core processing apparatus. The apparatus and method minimize performance degradation of a core caused by sharing resources by dynamically managing a maximum number of jobs assigned to each core of the apparatus. The apparatus includes at least one core including an active cycle counting unit configured to store a number of active cycles and a stall cycle counting unit configured to store a number of stall cycles and a job scheduler configured to assign at least one job to each of the at least one core, based on the number of active cycles and the number of stall cycles. When the ratio of the number of stall cycles to a number of active cycles for a core is too great, the job scheduler assigns fewer jobs to that core to improve performance.
