  • Patent number: 10037222
    Abstract: Technologies are generally provided to virtualize hardware acceleration. In some examples, a coprovisor component may be configured to multiplex multiple domains' requests to access a hardware accelerator such as a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or a comparable accelerator in a paravirtualized environment. Hyper-requesting may be employed for hardware acceleration virtualization, where a hardware acceleration module concurrently loads a portion of data of a request for a first accelerator application and a portion of data of another request for a second accelerator application and simultaneously processes the two portions of data. Directly situated on a device driver layer, the coprovisor may schedule portions of access requests to the hardware accelerator at the same time through direct memory access (DMA) context switching.

  • Patent number: 10037511
    Abstract: An approach to control workflow so that a relatively high priority work item can sometimes be automatically controlled by software to interrupt work being performed, by one or more resource unit(s), on a relatively lower priority work item. The analysis for deciding whether or not an interruption occurs depends upon interruptibility scalars (that is, interruptibility quotients and/or factors) and interruptibility threshold(s).

  • Patent number: 9940148
    Abstract: Techniques for in-place updates of hypervisors are described herein. At a time after receiving an update hypervisor request, one or more controlling domains within a computing system invoke one or more system capabilities at least to pause execution of currently running client domains and non-essential CPUs. While the client domains and non-essential CPUs are paused, a new hypervisor in instantiated, state information is copied from the existing hypervisor to the new hypervisor. After the state and/or configuration copy is complete, control is switched form the existing hypervisor to the new hypervisor and client domains and non-essential CPUs are resumed.

  • Patent number: 8799910
    Abstract: When a plurality of jobs are processed using a plurality of data processing units, data formats of the jobs to be processed can be determined to distribute a data processing load of the data processing units. A method for controlling a data processing apparatus for causing a plurality of data processing units to process data of a job includes storing data of a first job in a storing unit in first and second data formats, determining whether to process the stored data of the first job in the first or second data format, and causing the plurality of data processing units to process the data in the determined data format. The determination is made based on whether processing of data of a second job by the first or second processing unit requires longer time.

  • Patent number: 8473961
    Abstract: In response to a request for launching a program, a list of one or more application frameworks to be accessed by the program during execution of the program is determined. Zero or more entitlements representing one or more resources entitled by the program during the execution are determined. A set of one or more rules based on the entitlements of the program is obtained from at least one of the application frameworks. The set of one or more rules specifies one or more constraints of resources associated with the at least one application framework. A security profile is dynamically compiled for the program based on the set of one or more rules associated with the at least one application framework. The compiled security profile is used to restrict the program from accessing at least one resource of the at least one application frameworks during the execution of the program.

  • Patent number: 8291430
    Abstract: A mechanism for optimizing system performance using spare processing cores in a virtualized environment. When detecting a workload partition needs to run on a virtual processor in the virtualized system, a state of the virtual processor is changed to a wait state. A first node comprising memory that is local to the workload partition is determined. A determination is also made as to whether a non-spare processor core in the first node is available to run the workload partition. If no non-spare processor core is available, a free non-spare processor core in a second node is located, and the state of the free non-spare processor core in the second node is changed to an inactive state. The state of a spare processor core in the first node is changed to an active state, and the workload partition is dispatched to the spare processor core in the first node for execution.

  • Patent number: 8141083
    Abstract: A method, apparatus, and computer program product are disclosed for dynamically determining when to yield a processor that is assigned to perform particular work but that is currently idle. A particular processor is assigned to perform work. A determination is made regarding whether the processor is currently idle. If the processor is currently idle, a determination is made of a length of time the processor has been idle. If this determined length of time exceeds a self-tunable threshold, the processor is yielded to make the processor available to perform other work. The threshold can be dynamically tuned during runtime.

  • Patent number: 8056076
    Abstract: A method and system for acquiring a quiesceing set of information associated with a virtual machine. A virtual machine is cloned. The cloned virtual machine has an associated persistent storage device. The state of the persistent storage device is transformed into a quiesced state of the cloned virtual machine by utilizing a shut-down process. The shut-down process is executed on the cloned virtual machine to quiesce the cloned virtual machine and the quiesceing set of information of the cloned virtual machine is automatically reduced to information stored on the persistent storage device.

  • Patent number: 7984447
    Abstract: A method includes associating each computing job with a group of a plurality of groups, and associating each group with a minimum promised utilization. Further, the method includes determining a present utilization for each group having at least one job ready for scheduling, each job being associated with at least one required resource, the present utilization for a given group comprising a total amount of a promised resource consumed by presently executing jobs associated with the given group divided by the minimum promised utilization associated with the given group. A first computing job selected for scheduling is one that is ready for scheduling and is the computing job having a highest static priority within a group having a lowest present utilization. A subset of computing nodes able to satisfy the at least one required resource associated with the first computing job is identified.

  • Patent number: 7966616
    Abstract: A method, system, and computer program product for sharing adapter resources among multiple operating system instances. The present invention provides a mechanism for dynamically allocating virtualized I/O adapter resources. The present invention separates the operation of adapter resource allocation from adapter resource management. Protection attributes within the adapter resource context are used to allow the adapter to enforce access control over the adapter resources. The hypervisor allocates an available adapter resource to a given partition. The adapter is notified of the allocation, and the adapter updates its internal structure to reflect the allocation. The hypervisor may revoke ownership of and reassign adapter resources to another OS instance. In this manner, the allocation described above allows for the simple reassignment of resources from one partition to another.
