Abstract: Methods and apparatuses enable creation of a virtual machine (VM) clone initiated through application or service logic. The application requests generation of a VM clone from within the runtime execution of the application. The request is serviced by a VM generator, which identifies a state of the VM to clone and identifies hardware resources on which to create the VM clone. Based on a determination of what resources on which to generate the VM clone, the VM generator creates the VM clone on the determined resources, having the identified state. In one embodiment, a use case of resource copy or reference copy is selected for each resource. In one embodiment, the VM generator considers a number of factors in determining where to instantiate the VM clone. The parameters may include hints or preference parameters sent by the application and/or resource loading or performance.

Abstract: A method for determining status of system resources in a computer system includes loading a first operating system into a first memory, wherein the first operating system discovers system resources and reserves a number of the system resources for use of an augmenting operating system, loading the augmenting operating system into a second memory reserved for the augmenting operating system by the first operating system, accessing the first memory from the augmenting operating system and obtaining data, running a process on the augmenting operating system to perform a computation using the data obtained from the first memory, and outputting the results of the computation using the system resources reserved for the augmenting operating system.

Abstract: A dynamic approach for managing capacity in a storage environments accounting for various resource types, tiers, access paths, relationships among different storage environment components, as well as managing capacity in terms of resource planning and consumption is provided. Resource planning and consumption processes are used to allocate and reserve resources of different types and different tiers to each access path in the network. Capacity information for different resources types and tiers is automatically aggregated from different network components at different stages of a resource management cycle. The aggregated information may be used to estimate future resource needs or determine deviations between projected and actual status from which adjustments may be made to better predict future capacity needs.

Abstract: A system includes a virtualized I/O device coupled to one or more processing units. The virtualized I/O device includes a storage for storing a resource discovery table, and programmed I/O (PIO) configuration registers corresponding to hardware resources. A system processor may allocate the plurality of hardware resources to one or more functions, and to populate each entry of the resource discovery table for each function. The processing units may execute one or more processes. Given processing units may further execute OS instructions to allocate space for an I/O mapping of a PIO configuration space in a system memory, and to assign a function to a respective process. Processing units may execute a device driver instance associated with a given process to discover allocated resources by requesting access to the resource discovery table. The virtualized I/O device protects the resources by checking access requests against the resource discovery table.

Abstract: Mechanisms are provided for providing hardware based dynamic load balancing of message passing interface (MPI) tasks by modifying tasks. Mechanisms for adjusting the balance of processing workloads of the processors executing tasks of an MPI job are provided so as to minimize wait periods for waiting for all of the processors to call a synchronization operation. Each processor has an associated hardware implemented MPI load balancing controller. The MPI load balancing controller maintains a history that provides a profile of the tasks with regard to their calls to synchronization operations. From this information, it can be determined which processors should have their processing loads lightened and which processors are able to handle additional processing loads without significantly negatively affecting the overall operation of the parallel execution system. Thus, operations may be performed to shift workloads from the slowest processor to one or more of the faster processors.

Abstract: A mapping data generator determines a virtual page number of a virtual page where an executable code in an object file is mapped. A virtual page manager manages a virtual page record containing the virtual page number, a first object ID corresponding to the virtual page number, and a detection flag indicative of existence of another virtual page record containing a second object ID identical with the first object ID. A machine page manager manages a machine page record containing the first object ID, and a machine page number to which the virtual page number is mapped. A sharable page detector determines whether a detection flag indicates existence of another virtual page record containing the first object ID and determines whether a machine page number has been set. A page mapper maps a set machine page number to the virtual page number of the access page.

Abstract: In a global shared memory (GSM) environment, a method provides local notification of completion of a global shared memory (GSM) operation processed by a first task executing at a local node of the distributed system. The system includes multiple nodes on which different tasks of a single job execute and perform GSM operations that are received from a second task via a via host fabric interface (HFI) and associated HFR window assigned to the first tasks. The local task initiates execution of a GSM operation on the local node. The task then monitors for and detects a completion of the execution of the GSM operation on the local node. When the task detects completion of the execution of the GSM operation, the task issues an internal notification to inform the locally-executing tasks of the completion of the GSM operation.

Abstract: A driver is provided to manage launching of tasks at different levels of priority and within the parameters of the firmware interface. The driver includes two anchors for managing the tasks, a dispatcher and an agent. The dispatcher operates at a medium priority level and manages communication from a remote administrator. The agent functions to receive communications from the dispatcher by way of a shared data structure and to launch lower priority level tasks in respond to the communication. The shared data structure stores communications received from the dispatcher. Upon placing the communication in the shared data structure, the dispatcher sends a signal to the agent indicating that a communication is in the data structure for reading by the agent. Following reading of the communication in the data structure, the agent launches the lower priority level task and sends a signal to the data structure indicating the status of the task.

Abstract: A distributed processing system delegates the allocation and control of computing work units to agent applications running on computing resources including multi-processor and multi-core systems. The distributed processing system includes at least one agent associated with at least one computing resource. The distributed processing system creates work units corresponding with execution phases of applications. Work units can be associated with concurrency data that specifies how applications are executed on multiple processors and/or processor cores. The agent collects information about its associated computing resources and requests work units from the server using this information and the concurrency data. An agent can monitor the performance of executing work units to better select subsequent work units. The distributed processing system may also be implemented within a single computing resource to improve processor core utilization of applications.

Abstract: A utilization analyzer acquires accumulator values from multiple accumulators. Each accumulator corresponds to a particular processor thread and also corresponds to a particular processor utilization resource register (PURR). The utilization analyzer identifies, from the multiple accumulators, a combination of equal accumulators that each includes a largest accumulator value. Next, the utilization analyzer selects a subset of processor utilization resource registers from a combination of processor utilization resource registers that correspond to the combination of equal accumulators. The subset of processor utilization resource registers omits at least one processor utilization resource register from the combination of utilization resource registers. In turn, the utilization analyzer increments each of the subset of utilization resource registers.
