A method and apparatus for enforcing capacity limitations such as those imposed by software license agreements in an information handling system in which a physical machine is divided into a plurality of logical partitions, each of which is allocated a defined portion of processor resources by a logical partition manager. A software license manager specifies a maximum allowed consumption of processor resources by a program executing in one of the logical partitions. A workload manager also executing in the partition measures the actual consumption of processor resources by the logical partition over a specified averaging interval and compares it with the maximum allowed consumption. If the actual consumption exceeds the maximum allowed consumption, the workload manager calculates a capping pattern and interacts with the logical partition manager to cap the actual consumption of processor resources by the partition in accordance with the calculated capping pattern. To provide additional capping flexibility, partitions are assigned phantom weights that the logical partition manager adds to the total partition weight to determine whether the partition has exceeded its allowed share of processor resources for capping purposes. The logical partition thus becomes a “container” for the licensed program with an enforced processing capacity less than that of the entire machine.

An Electronically-Controlled Register vent (ECRV) that can be easily installed by a homeowner or general handyman is disclosed. The ECRV can be used to convert a non-zoned HVAC system into a zoned system. The ECRV can also be used in connection with a conventional zoned HVAC system to provide additional control and additional zones not provided by the conventional zoned HVAC system. In one embodiment, the ECRV is configured have a size and form-factor that conforms to a standard manually-controlled register vent. In one embodiment, a zone thermostat is configured to provide thermostat information to the ECRV. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones.

A computer system including a plurality of physical processors (CPs) having physical processor performances (PCPs), a plurality of logical processors (LCPs), a plurality of logical partitions (LPARs) where each partition includes one or more of the logical processors (LCPs), and a system assist processor having a control element. The control element controls the virtualization of the physical processors (CPs), the logical partitions (LPARs) and the logical processors (LCPs) and allocates the physical processor performances (PCPs) to the logical partitions (LPARs). The control element operates to exclusively bind logical processors (LCPs) to the physical processors (CPs). For a logical processor (LCP) exclusively bound to a physical processor (CP), the logical processor (LCP) has exclusive use of the underlying physical processor (CP) and no other logical processor (LCP) can be dispatched on the underlying physical processor (CP) even if the underlying physical processor (CP) is otherwise available.

Methods and systems for auto-configuration of an internal network interface are disclosed. Embodiments may install an internal VLAN manager in a logically partitioned computer system along with network agents in each of the partitions in the logically partitioned system to facilitate configuring an internal communications network and the corresponding internal network interfaces in each participating partition. In particular, an administrator accesses internal VLAN manager, selects an internal VLAN ID, selects each of the participating partitions, and configures the communications network with global parameters and ranges. The internal VLAN manager then generates partition parameters and incorporates them into messages for each of the partitions selected to participate in the internal network. Each of the participating partitions receives one of the messages and, in response, invokes the corresponding network agent that extracts partition parameters from the message and creates or re-configures an internal network interface based upon the parameters.

A modular device, system and associated method, used to enhance the quality and output speed of any generic GPS engine is provided. The modular device comprises an inertial subsystem based on a solid state gyroscope having a plurality of accelerometers and a plurality of angular rate sensors designed to measure linear acceleration and rotation rates around a plurality of axes. The modular inertial device may be placed in the data stream between a standard GPS receiver and a guidance device to enhance the accuracy and increase the frequency of positional solutions. Thus, the modular inertial device accepts standard GPS NMEA input messages from the source GPS receiver, corrects and enhances the GPS data using computed internal roll and pitch information, and produces an improved, more accurate, NMEA format GPS output at preferably 2 times the positional solution rate using GPS alone. The positional solution frequency using the present invention may increase to as much as 5 times that obtained using GPS alone. Moreover, the modular inertial device may assist when the GPS signal is lost for various reasons. If used without GPS, the modular inertial device may be used to define, and adjust, a vehicle's orientation on a relative basis. The modular inertial device and architecturally partitioned system incorporated into an existing GPS system may be applied to navigation generally, including high-precision land-based vehicle positioning, aerial photography, crop dusting, and sonar depth mapping to name a few applications.

An intelligent virtual global interrupt queue (virtual GIQ) that may be associated with a plurality of virtual processors running in a logical partition may be utilized. Upon receiving a virtual interrupt, the virtual GIQ may examine the operating states of the associated virtual processors.

A time-partitioned system for accounting for processor time consumed by operating system services provided on behalf of an application runs in a real-time environment. The time utilized by the operating system is treated as application processing time, rather than viewing the resultant processor time consumed as an operating system overhead. Each application consists of one or more threads. A time budget is assigned to each thread and to each interrupt. The processor time consumed by the operating system when executing on behalf of a thread or interrupt is charged back to the application or interrupt as part of the application's time budget. Operating system overheads and processor interrupts are thus accounted for accurately enough to determine a schedule for the applications that is enforceable by the operating system at run time.

A second support member extends downwardly from the raceway, and has a connector spaced apart from the raceway a second vertical distance that is different from the first vertical distance, such that the raceway is supported at a generally uniform vertical height above an upper edge of a partition having sections with different heights.

A method, apparatus, and computer instructions for reporting global errors in a logical partitioned data processing system having a plurality of partitions running different types operating systems. Responsive to detecting a global error, a unique identifier is assigned to the global error. The unique identifier is sent to a service focal point. The unique identifier also is sent to the partitions. Error information from the partitions is reported to the focal point. The partitions send error information to the focal point in association with the unique identifier. The focal point identifies error information sent from the partitions for the global error using the unique identifier.
