Abstract: A system for providing features at launch to an application. The system may execute a user-space launcher application. To execute the launcher application, the computing system may: wrap a process creation function with a process creation wrapper function, preload a function library comprising the process creation function, launch an application specified to the launcher application, intercept a call to the process creation function of the launched application with the process creation wrapper function, create a process on behalf of the launched application using the process creation function, and provide a feature at launch to the process of the launched application based on a parameter specified to the launcher.

Abstract: Examples disclosed herein relate to backing up persistent memory. There is at least one memory addressable by at least one processor. The persistent memory includes a persistent memory region with multiple portions. A secondary storage includes a first backup of the persistent memory region. Modifications to the persistent memory region are tracked. Updated portions associated with the modifications are written to the secondary storage.

Abstract: In one example, a system includes an out-of-band monitoring engine to determine system state information by monitoring a system state of the system and a dump engine to provide the system state information to a computing device for analysis. The out-of-band monitoring engine can determine system state information in response to a failure of an operating system during start-up, determine system state information in response to a catastrophic error occurring to an operating system, and determine system state information of a functioning operating system.

Abstract: Dumping resources can include identifying a resource associated with a computing device, dumping the resource associated with the computing device, determining whether the resource has changed since the resource has been dumped, and dumping the resource, prior to a crash of the computing device occurring, when the resource has changed since the last dump.

Abstract: Computer processes are allocated among cores of a multi-core multi-processor system at least in part as a function of utilization histories of the processes.

Abstract: Methods of method of managing memory power usage in a computing device having two or more memory modules. By monitoring a system working set size of the computing device, a determination can be made if all active memory modules are needed for the system working set size. If not all active memory modules are needed for the system working set size, one or more of the active memory modules can be selected for power down. By evacuating data from the selected one or more memory modules, placing the evacuated one or more memory modules in a power-down state, and removing the powered-down memory modules from the active memory of the computing device, memory power usage can be reduced.

Abstract: A computer system has plural partitions for running respective workloads. Reliability-indicating events are monitored and the resulting data is used by a workload manager in allocating computer resources to workloads.

Abstract: A computer system includes software running on a hardware platform. The hardware platform provides a platform manager having an user interface that is independent of that for a mission operating system running on said platform. The platform manager issues platform requests for power-setting adjustments. The software includes a mission operating system with a power controller incorporated in or running on the mission operating system. The power controller adjusts power settings for hardware devices at least in part as a function of the platform requests.

Abstract: The present invention provides a computer-implemented limited right-to-use business method. In response to a command to change the right-to-use status of at least a first component, the right-to-use status of said processor is changed in a direction either from reserved to available or from available to reserved. Then, the power state of the component can be changed as a function of that direction.

Abstract: The present invention provides for redistributing workloads among computers to optimize resource utilization. Utilization by software workloads of computer resources is monitored to yield utilization data. A utilization chronology is updated using the utilization data. The chronology is analyzed to yield resource utilization predictions. The workloads are redistributed among the resources at least in part as function of said predictions.

Abstract: A server manages power and performance. The server comprises a plurality of processor and associated storage and input/output interface components, arranged into a plurality of independent compute cells. One or more performance metrics descriptive of performance of the independent compute cell plurality are selected and an optimization evaluation of the one or more performance metrics is performed. The independent compute cell plurality is tuned based on the optimization evaluation.

Abstract: A method of reducing power consumption of a computing system by a predetermined amount comprises: selecting at least one memory component of the computer system for reduced power consumption based on the predetermined amount of power consumption reduction; and evacuating the selected at least one memory component to reduce the power consumption of the computing system by at least the predetermined amount.

Abstract: A computer system takes redundancy into account when allocating hardware resources to workloads in the event of a failure of a non-data-handling component.

Abstract: In an embodiment of the invention, a method for dynamic hardware multithreading, includes: using a hardware halt function or a hardware yield function in a processor core in order to enable or disable a hardware thread that shares the core; wherein the hardware thread is disabled by placing the hardware thread in a halt state or yield state, and allowing another hardware thread to utilize the core.
