Abstract: Systems and methods are described for managing virtual machine hibernation state incompatibility on hosted computing environments. Hibernated virtual machine instances may have limited compatibility with configurations of underlying host devices, such that attempting to awaken the virtual machine instance on a host device of a different configuration fails. This can be problematic, for example, as configurations of hosted computing devices change within an environment. The present disclosure addresses this issue by monitoring availability of a host device configuration, and, when the availability drops below a threshold, repairing the virtual machine hibernation state such that it is compatible with a new hosted device configuration.

Abstract: Techniques are described herein for allocating and rebalancing computing resources for executing graph workloads in manner that increases system throughput. According to one embodiment, a method includes receiving a request to execute a graph processing workload on a dataset, identifying a plurality of graph operators that constitute the graph processing workload, and determining whether execution of each graph operator is processor intensive or memory intensive. The method also includes assigning a task weight for each graph operator of the plurality of graph operators, and performing, based on the assigned task weights, a first allocation of computing resources to execute the plurality of graph operators. Further, the method includes causing, according to the first allocation, execution of the plurality of graph operators by the computing resources, and monitoring computing resource usage of graph operators executed by the computing resources according to the first allocation.

Abstract: In example implementations, a method include receiving a request for a lock in a Mellor-Crummey Scott (MCS) lock protocol from a guest user that is context free (e.g., a process that does not bring a queue node). The lock determines that it contains a null value. The lock is granted to the guest user. A pi value is received from the guest user to store in the lock. The pi value notifies subsequent users that the guest user has the lock.

Abstract: An on-demand code execution environment present in points of presence (POPs) and in regions serviced by the POPs is provided herein. For example, a POP may receive a request to execute a task associated with user-defined code. If the POP determines that the computing resources necessary to execute a received task are not available or that the POP should not execute the received task for another reason (e.g., the task is not commonly received and the computing resources needed to execute the task are therefore best allocated for other requests), the POP can forward the task to a region that the POP services for execution by an on-demand code execution environment present in the region. The on-demand code execution environment present in the region can execute the task and forward the results of the execution to the POP for distribution back to a user device that requested the task execution.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes an initialization component of a host. The initialization component requests from a service processor of the host a first replacement firmware image of a first device of the host. The initialization component then receives the first replacement firmware image from the service processor. The initialization component further provides the first replacement firmware image to a first updating program. The initialization component uses the first updating program to replace the first existing firmware image on the first device with the first replacement firmware image.

Abstract: Provided is a method, system, and computer program product for managing tasks in a computing system using a virtual node. A processor may register a virtual node for handling tasks allocated by a scheduling node in a computing system, the computing system comprising the scheduling node and a group of actual computing nodes processing tasks allocated by the scheduling node, and the scheduling node takes the virtual node as an actual computing node. A performance level of the computing system is obtained. Capacity of the virtual node is set based on the obtained performance level, such that the scheduling node allocates tasks to the virtual node based on the capacity of the virtual node. In response to at least one task being allocated by the scheduling node to the virtual node, the at least one task is received by the virtual node.

Abstract: A method of controlling a data processor to perform data processing operations is disclosed in which a host processor prepares one or more queue(s) of operations for execution by the data processor. When an error is encountered in the processing of an operation for one of the one or more queue(s), a queue can be set into an error state in which instructions that may have a data dependency on another operation are not executed. The host processor includes in the queues error barrier instructions that divide the respective queues into sets of operations between which there are no data processing dependencies. An error state for a queue can thus be cleared when its processing reaches the next error barrier instruction in the queue.

Abstract: A plurality of virtual machines executing on physical machines may be monitored, and performance data characterizing consumption of physical resources of the physical machines by the plurality of virtual machines during the observation time may be extracted. Each of the plurality of virtual machines may be classified as active or idle during each time division of a plurality of time divisions of the observation time, based on the performance data and on idleness criteria, to thereby generate an active-idle series for each of the plurality of virtual machines. For each active-idle series of each virtual machine of the plurality of virtual machines, at least one periodicity of recurring idle times within the observation time may be determined. Then, for each virtual machine with the at least one periodicity, an on-off schedule may be determined, and each of the virtual machines may be transitioned with the at least one periodicity between an on state and an off state in accordance with the on-off schedule.

The data is transferred over virtual networks using virtual dispersive routing and stored in dispersive storage area networks (SANs). The data is classified as trusted, corrupted, invalid or uncertain, and/or as trusted, ambiguous and inadequate.

Abstract: A flexible, adaptive performance test platform allows a test developer to customize performance tests to more realistically determine the impact of network behavior on a system under test. The test platform may be accessed through the use of a Graphic User Interface (GUI) by all developers within an enterprise to generate and execute performance tests prior to release of new systems by the enterprise. In one aspect, the test platform enables developers to share performance tests, thereby leveraging existing work product to reduce the overall system development time. In another aspect, the test platform enables developers to customize performance tests, providing the flexibility to easily specify a duration, scale, geography and/or resource for the test. In another aspect, the test platform enables developers to customize and monitor one or more metrics in accordance with the particular performance goals of the SUT, to enable a developer to more easily identify system issues.

Abstract: A technique is described herein for updating the logic used by a hardware accelerator provided by a computing device. In one implementation, the technique provides a pass-through mode which allows a virtual machine (provided by the computing device) to directly interact with the hardware accelerator. Upon the commencement of an updating operation, the technique instructs an emulator to begin emulating the function(s) of the hardware accelerator and the resultant effects of these functions, without interaction with the actual hardware accelerator. When the updating operation finishes, the technique re-enables the pass-through mode. By virtue of the above-summarized manner of operation, the technique allows the computing device to perform the function(s) associated with the hardware accelerator while the hardware accelerator is being updated. In one case, the technique disables the pass-through mode by modifying address-mapping information used by the virtual machine to access system physical addresses.

Abstract: Computer (or computerized) numerical control (CNC) tools are employed globally. Whilst these may be purchased with an initial set of configurations users must establish any other configurations themselves leading to potentially every CNC tool being configured slightly differently for the same process requirement even before considering new materials, tool elements etc. Accordingly, users and manufacturers would benefit from access to updated process parameters for machine tools that reflect scenarios encountered in manufacturing operations that are new or lead to improved tolerances, yields, reducing process time etc. However, users are not going to employ just any set of parameters given to them as these may damage their CNC tool or tool elements. Embodiments of the invention provide a subscription service providing access to verified settings where the verification is performed by the machine tool manufacturer or machine tool element manufacturer.
