In one embodiment, a cache element allocation method is provided. Each cache element on a CPU is assigned a quality rank based on the error rate of the cache element. If an allocated cache element is deemed to be faulty, the quality rank of the faulty allocated cache element is compared with the quality rank of the non-allocated cache elements. If a non-allocated cache element has a lower quality rank than the allocated cache element, the non-allocated cache element is swapped in for the allocated cache element.

Systems and methods for CPU repair

In one embodiment, a CPU cache management system is provided. The CPU management system includes, for example, a CPU chip and cache management logic. The CPU chip include cache elements that are initially in use and spare cache elements that not initially in use. The cache management logic determines whether currently-used cache elements are faulty. If a cache element is determined to be faulty, the cache management logic schedules a reboot of the computer and swaps in a spare cache element for the faulty currently-used cache element during the reboot.

A method, executed on a computing device, and a corresponding system, allow software applications to easily access data contained in a static XML document by parsing the static XML document. For each node in the XML document, a Node Offset value is determined. The Node Offset value is then stored and serves as an index offset value, where the index offset value is used by the software applications to retrieve the data contained in the static XML document.

System and method for using indexes to parse static XML documents

Systems and methods for repairing a processor are provided. In one embodiment, a method for repairing a processor is provided that includes, for example, the steps of initializing and executing an operating system, determining that a cache element is faulty, and swapping in a spare cache element for said faulty cache element while the operating system is executing.

Systems and methods for conducting processor health-checks are provided. In one embodiment, a method for evaluating the status of a processor is provided. The method includes, for example, initializing and executing an operating system, de-allocating the processor from the available pool or system resources and performing a health-check on the processor while the operating system is executing.

Methods and systems for conducting processor health-checks

In one embodiment, a method for repairing a faulty cache element is provided. Once a monitored cache element is determined to be faulty, the system stores the repair information, and cache configuration in an EEPROM or non-volatile memory on the CPU module. Then the computer is rebooted. During the reboot, the faulty cache element is repaired by being swapped out for a spare cache element based on the information stored in the EEPROM or the non-volatile memory.
