摘要： An approach that optimizes system performance using performance monitors is presented. The system gathers thread performance data using performance monitors for threads running on either a first ISA processor or a second ISA processor. Multiple first processors and multiple second processors may be included in a single computer system. The first processors and second processors can each access data stored in a common shared memory. The gathered thread performance data is analyzed to determine whether the corresponding thread needs additional CPU time in order to optimize system performance. If additional CPU time is needed, the amount of CPU time that the thread receives is altered (increased) so that the thread receives the additional time when it is scheduled by the scheduler. In one embodiment, the increased CPU time is accomplished by altering a priority value that corresponds to the thread.

摘要： Initially, a SMI trap detects an application accessing a memory location associated with a physical hardware device. The SMI trap receives the device address for the address bus and compares that address with memory addresses for hardware devices being virtualized by virtual device simulators. If the address matches an available virtual device, the SMI caches the address, hooks and caches the corresponding IO instruction for the memory address and issues a SMI. A SMI handler receives the SMI and determines which virtual device simulator to call. Once activated by the SMI handler, the virtual device simulator interacts with the application and then returns control to the processor.

摘要： A method and system for automatically configuring a boot process of a network computer initially connected within a network comprising at least one server. A request is broadcast from a network computer to a network for an available server, upon a first initiation of the network computer within the network. Responses from the broadcast are gathered which indicate whether a server is available. A selected boot program is then executed from among multiple boot programs available in the network computer. The selected boot program and the identity of an available server are stored as boot process configuration settings in a nonvolatile storage of the network computer, in response to successful execution of the boot program, such that a subsequent boot process of a network computer is automatically configured.

摘要： A computer system including a processor, a system memory, and a boot code storage device. The system memory is connected to the processor and is suitable for storing processor data and instructions. The boot code storage device includes an image selection indicator for indicating which of multiple boot code images are to be loaded. The computer system further includes means for initiating a boot sequence stored on the boot code storage device. The boot sequence selects from first and second boot images based upon the state of the image selection indicator and loads the selected image into the system memory in response to a boot event. In one embodiment, the image selection indicator is in an initial state until the boot code sequence successfully loads a boot image. The image selection indicator is set to a value indicative of the loaded image when one of the boot images is successfully loaded. The boot code storage sequence attempts, in the preferred embodiment, to load the previously load boot image when the system detects a setting of the image selection indicator indicative of a previously loaded boot image. In the preferred embodiment, the boot code sequence responds to a specified user input sequence by presenting the user with a configuration screen suitable for altering the value of the image selection indicator such that the user may later the boot image that will be loaded during a subsequent execution of the boot sequence. In one embodiment, the first boot image is a BIOS based boot image and the second image is a network based (non-BIOS) boot image. The boot code storage device is preferably a flash memory device.

摘要： Code handling, such as interpreting language instructions or performing “just-in-time” compilation, is performed using a heterogeneous processing environment that shares a common memory. In a heterogeneous processing environment that includes a plurality of processors, one of the processors is programmed to perform a dedicated code-handling task, such as perform just-in-time compilation or interpretation of interpreted language instructions, such as Java. The other processors request code handling processing that is performed by the dedicated processor. Speed is achieved using a shared memory map so that the dedicated processor can quickly retrieve data provided by one of the other processors.

In one embodiment, the power fail circuit includes a flip flop arranged such that the output of the flip flop is preset when power is restored to the network client after a power failure. Preferably the clear input of the flip flop is programmably assertable. The power status indicator preferably further includes a power mode indicator that conveys information about the last known power mode of the network client. Preferably, the power mode indicator includes at least one nonvolatile memory bit.

摘要： A boot code storage device configured with computer instructions for executing a boot code validity check in response to a boot event to facilitate local recovery of a computer such as a network computer. In response to the boot event, such as powering up a computer in which the boot code storage device is located, an image of a boot code is copied from a first storage medium to the boot code storage device if the validity check is negative. Remaining portions of the boot code, including a start up sequence, are executed if the validity check is positive. In one embodiment, the boot code validity check determines the presence or absence of a boot code jumper in a motherboard to which the boot code storage device is connected. In the preferred embodiment, the boot code storage device comprises a flash memory device, preferably including a plurality of sectors. In the preferred embodiment, the boot code validity check is part of a boot block of the boot code residing in a first sector of the flash memory device. The boot block and boot code reside in contiguous memory of the boot code storage device in one implementation. The first storage medium from which the boot code is copied, in one embodiment, is a compact flash card configured with an image of the boot code.
