摘要： A system for and method of monitoring memory transactions in a data processing system are disclosed. The method includes defining a set of memory transaction attributes with a monitoring system and detecting, on a data processing system connected to the monitoring system, memory transactions that match the defined set of memory transaction attributes. The number of detected memory transactions occurring during a specified duration are then displayed in a graphical format. In one embodiment, the data processing system comprises a non-uniform memory architecture (NUMA) system comprising a set of nodes. In this embodiment, the detected transactions comprise transactions passing through a switch connecting the nodes of the NUMA system. The set of memory transaction attributes may include memory transaction type information, node information, and transaction direction information. The data processing system may operate under a first operating system such as a Unix® based system while the monitoring system operates under a second operating system such as a Windows® operating system. The set of memory transactions may include memory address information. In this embodiment, defining the memory address information may include defining a memory window size, subdividing the memory window into a set of memory grains, and displaying the number of detected memory transactions corresponding to each memory grain in the memory window.

摘要： A system and method for providing in-server caching of shared data involves a server program that defines a server cache in RAM of a server machine and stores a selected file in the server cache. If a cached file is modified through the file system interface of the operating system of the server machine, the operating system automatically issues an upcall to the server program, the upcall identifying the modified file. In response to receipt of the upcall, the server program removes the modified file from the server cache. In one embodiment, the server program responds to a client request requiring access to a requested file by obtaining the requested file from the server cache if the server cache contains that file. Otherwise, the server program calls the operating system to obtain the requested file and then adds that file to the server cache as a cached file. The server program then generates a result based on the requested file and transmits the result to the remote data processing system.

摘要： A performance monitor for a computer system that includes an interface, a filter module, and an address mapping module. The interface is suitable for coupling to an interconnect network of the computer system. The interconnect network links a local node of the system with at least one remote node of the system. The interface is configured to extract physical address information from a transaction traversing the interconnect network. The filter module associates the physical address with one of several memory blocks, where each memory block comprises a contiguous portion of the system's physical address space. The address mapping module associates the identified memory block with at least one range of virtual addresses associated with at least one of a plurality of concurrently executing programs and increments each of a set of access counters. The association between the selected memory block and the access counters is facilitated by a pointer field corresponding to the memory block.

摘要： A method and system for optimizing image quality while operating an interactive graphics application within a data processing system. First, the image rendering speed for each of the rendering modes available within the interactive graphics application are assessed. Upon initial operation of the interactive graphics system, a default rendering mode is activated. During operation of the interactive graphics application, the processing load imposed on the data processing system is monitored and utilized as a user activity metric. The active rendering mode is updated in accordance with the user activity metric, such that the speed of the selected rendering mode varies inversely with the current processing load.

摘要： A data processing network and method for conserving energy in which an initial negotiation between a network server and a switch to which the server is connected is performed to establish an initial operating frequency of the server-switch link. An effective data rate of the server is determined based on network traffic at the server. Responsive to determining that the effective data rate is materially different than the current operating frequency, a subsequent negotiation is performed to establish a modified operating frequency where the modified operating frequency is closer to the effective data rate than the initial operating frequency. The determination of the effective date rate and the contingent initiation of a subsequent negotiation may be repeated periodically during the operating of the network. In one embodiment, the initial and subsequent negotiation are compliant with the IEEE 802.3 standard.

摘要： A method and controller for managing power and performance of a multiprocessor (MP) system is described. The controller receives sensor data corresponding to physical parameters within the MP system. The controller also receives quality of service and policy parameters corresponding to the MP system. The quality of service parameters define commitments to customers for utilization of the MP system. The policy parameters correspond to operation limits on inputs and outputs of the MP system. The operation input limits relate to the cost and availability of power or individual processor availability. The operation output limits relate to the amount of heat, acoustic noise levels, EMC levels, etc. that the individual or group of processors in the MP system are allowed to generate in a particular environment. A controller receives the physical parameters, the quality of service parameters and policy parameters and determines performance goals for the MP system and processors within the MP system. Then controller generates controls and applies them to individual processors to achieve the performance goals.

摘要： A method and apparatus for providing a dynamically alterable output clock from an input clock based on the value of an integer, where the integer can be modified continuously. The invention also provides a sample cycle output which is an enable pulse, having the width of the input clock cycle, that is asserted one or two input clock cycles prior to the rising edge alignment of the input and output clocks, that acts as a rising edge alignment enable signal, maintaining a one-to-one correspondence between the sample cycle assertions and rising edge alignment events, regardless of the dynamic changes in the value of the integer.

摘要： A system in which bus signals are selectively modified to effectively isolate desired bus agents from the bus. The selective modification of bus signals may be determined from a stored table (permission table) indicating permitted and prohibited bus transaction initiator/target pairs. The permission table may be located in a dedicated device, such as a programmable logic array or application specific integrated circuit. Alternatively, the permission table may be integrated into the bus arbiter. The permission table may be used to provide a unique 1-bit signal to each bus agent indicating whether the corresponding bus agent is permitted to receive transactions from the current bus master. The permission bit may be routed to external gating circuitry associated with each bus agent. The gating circuitry may receive one or more bus control signals and may modify the control signals depending upon the state of the permission bit. In an embodiment in which the bus is a PCI bus, the gating circuitry may receive the FRAME# and GNT# signals for each bus agent.
