Provided is a method of managing resource starvation in a computer system. A highest priority task is created in a computer system. The highest priority task identifies a resource starvation causing task in the computer system and reduces current priority of the starvation causing task.

Resource starvation management in a computer system

The invention provides for software fault detection. A software process tracks its own progress. In the event the timer times out, a handler checks the progress. If the progress meets a fault criterion, a fault response is executed.

First and second management systems are placed in active and standby modes, respectively. The first and second management systems are configured to be in communication with the second and the first management systems, respectively and with a plurality of network devices. A first number of the plurality of network devices in communication with the first management system is determined at the first management system and transmitted to the second management system. A second number of the plurality of network devices in communication with the second management system is determined at the second management system and transmitted to the first management system. A first determination is made regarding whether the first number of network devices is less than the second number of network devices at the first management system. A second determination is made regarding whether the first number of network devices is less than the second number of network devices at the second management system. The first and second management systems are placed in failure mode and active mode, respectively based on the first and second determinations.

Embodiments of the invention disclose a method of determining the existence of state synchronization between two redundant processing modules operating in a network switch that operates in a manner wherein ordinary network traffic stimuli are autonomously processed through interface and fabric modules, and extraordinary network stimuli are processed from the interface modules to the redundant processing modules, wherein one of the modules is operating actively in the switch and the other is operating in a standby condition whereby state latency exists between the two modules, comprising stopping processing of the extraordinary stimuli to the actively operating processing module, completing processing of stimuli previously received by the actively operating processing module, completing processing of stimuli previously received by the processing module operating in a standby condition, reading the state information of each of the two processing modules, and comparing the state information of said two processing modules to determine if their state information is synchronized, and resuming processing extraordinary stimuli by the actively operating processing module.

In one embodiment of the invention, a method for printer driver initialization for a non-Microsoft Windows system, includes: copying a selected printer driver from a remote system to a local system, and installing the printer driver on the local system; initializing the printer driver on the local system and generating initialization information for the initialized printer driver; cloning the initialization information, and storing the cloned initialization information on the remote system; and binding the cloned initialization information to the selected printer driver. The remote system may be a non-Microsoft Windows system. The local system may be a Microsoft Windows system.

A remote computer display for a portable computing device (PCD) utilizing the transfer of graphics primitives over a wireless data link. The present invention utilizes a wireless (RF or optical) transmitter built into a portable computing device to send graphics commands to a remote computer display. A receiver receives the wireless signals and converts the signals into data which produces a graphics image of the remote computer display. To reduce the data link bandwidth needed to transfer images from the PCD to the remote display, graphics primitives such as HPGL are sent over the data link. The PCD includes a video driver to convert video display requests made by the PCD operating system, or an application program executing on the PCD, into the graphics primitives which are then transferred to the remote display over the data link.
