Abstract: A data processing system comprises one or more data processing units, a configurable interconnect and control circuitry. The control circuitry allocates one or more of the data processing units to a virtual machine and configures the configurable interconnect so as route one or more data processing tasks from the virtual machine to the one or more data processing units allocated for use by that virtual machine. This can provide a flexible and adaptable data processing system for carrying out the data processing tasks of a virtual machine, with the particular allocation of data processing units being substantially transparent to the virtual machine.

Abstract: According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions that are to cause the processor to receive an allocation request from an allocator client, determine a resource allocation for the received job allocation request, store a record of the determined resource allocation in a records store, and send the determined resource allocation to the allocator client, in which an acknowledgement to the sent determined resource allocation is to be received from the allocator client. The instructions may also cause the processor to manage a state of the determined resource allocation using the record stored in the records store based on whether the acknowledgement is received from the allocator client.

Abstract: An example system includes one or more resource managers forming a federation of resources, at least one resource manager being associated with one or more resources; a federation hub for receiving local resource information from each of the one or more resource managers, wherein the federation hub aggregates the local resource information from each of the one or more resource managers and provides an aggregated view of all resources of the federation; and a bylaw guardian for determining compliance of each of the one or more resource managers to requirements of the federation.

Abstract: Methods and apparatus for virtual machine (VM) load monitoring in provider network environments. A VM load monitor system may be used to offload the processing of VM load data from the execution environment of a VM host device. A VM load monitor may be implemented as a dedicated programmable hardware device on or attached to a host device that is external to the execution environment of the host device, thus freeing host device resources (e.g., processors, memory, etc.) for use by the VMs executing on the host device. The VM load monitor may make VM management decisions for the host device (e.g. launch VM decisions, migrate VM decisions, etc.) based on analysis of resource load data (e.g. network, memory, and/or processor load data) collected from the VMs (or groups of VMs) executing on the host device.

Abstract: The present invention involves systems and methods for replacement of function calls. In one embodiment, a function call is intercepted and modified to enforce a policy on a client device. The function call is intercepted by scanning code loaded for a launch of an application. The function call includes a first pointer value. The function call is modified by changing a first pointer value to a second pointer value. The second pointer value points to a customized function.

Abstract: Embodiments include method, systems and computer program products for operating a computer system using a workload manager to control a dynamic thread mode switch. The method includes receiving a plurality of workloads. A workload manager determines which of the plurality of workloads are eligible to use a processor core operating in a multi-threaded mode and which workloads are response sensitive and use a processor core operating in a single-thread mode. A hypervisor determines a state of operation for one or more cores of one or more processors and causes a core switch for at least one or more cores in response to a determination that workloads eligible to use a processor core operating in a multi-threaded mode exist or workloads that are response sensitive and a determination that the state of operation for one or more cores of one or more processors should change to facilitate handling the associated workloads.

Abstract: A system and method include determining, by a telemetry control system of a telemetry system that an agent associated with the telemetry control system terminated during operation. The agent collects telemetry data from data sources associated with the telemetry system. The system and method also include determining that a number of times the agent has terminated is greater than a predetermined threshold, restarting the agent after a first predetermined delay in response to exceeding the predetermined threshold, and determining that the agent terminated again within a predetermined time period upon restarting. The system and method further include updating a configuration file of the agent in response to the termination within the predetermined time period and restarting the agent with the updated configuration file. The updating is based upon an agent termination record of the agent.

Abstract: The disclosure provides an approach for modifying a kernel by adding conditional halting points. The disclosure also provides an approach for modifying a kernel by implementing a virtual shared memory between an application running on a CPU and a workload running on a compute accelerator. The disclosure provides an approach for setting up the kernel and its working set on a compute accelerator, executing the workload, suspending the workload, and then resuming the workload at a later time, optionally on a different host computer.

Abstract: A security module in a memory access path of a processor of a processing system protects secure information by verifying the contents of memory pages as they transition between one or more virtual machines (VMs) executing at the processor and a hypervisor that provides an interface between the VMs and the processing system's hardware. The security module of the processor is employed to monitor memory pages as they transition between one or more VMs and a hypervisor so that memory pages that have been altered by a hypervisor or other VM cannot be returned to the VM from which they were transitioned.

Abstract: The threads of a user mode process can access various different resources of a computing device, and such access can be serialized. To access a serialized resource, a thread acquires a lock for the resource. For each context switch in the computing device, a module of the operating system kernel checks for priority inversions, which is a situation in which a higher priority thread of the user mode process is waiting for (blocking on) a resource for which a lower priority thread has acquired a lock. In response to detecting such a priority inversion, the priority of the lower priority thread is boosted to allow the priority thread to execute and eventually release the lock that the higher priority thread is waiting for.

Abstract: An efficient state-machine-based pattern matching technique processes tokens in an input queue and identifies patterns in the sequence of tokens that match one or more predetermined input patterns without backtracking. Tokens can include data or no data and a time component. The tokens can be a stream of data generated by a sensor, which transforms a physical property into a digital quantity. The pattern matching technique processes the input queue in a single direction, and does not examine any previously examined token. In an implementation, specific patterns to be matched are specified using a state machine, where the state machine is specified in a state table and operates using a state stack.
