摘要:
A flexible input/output controller logic interfaces with existing input/output controllers (IOC's) in order to configure the amount of data sent to and received from the IOC's. The flexible I/O interface receives data from a component at a rate determined by the particular component. The flexible I/O interface then feeds the received data to a traditional I/O controller at a rate suitable for the I/O controller. Thus, the interface to the individual I/O controllers is maintained. The flexible I/O logic balances bandwidth between a plurality of individual I/O controllers in order to better utilize the overall system I/O bandwidth. In one embodiment, the I/O configuration managed by the flexible I/O logic is determined during system-build, while in another embodiment, the I/O configuration is set during system initialization.

A method, system, apparatus, and article of manufacture for performing cacheline polling utilizing a store and reserve instruction are disclosed. In accordance with one embodiment of the present invention, a first process initially-requests an action to be performed by a second process. A reservation is set at a cacheable memory location via a store operation. The first process reads the cacheable memory location via a load operation to determine whether or not the requested action has been completed by the second process. The load operation of the first process is stalled until the reservation on the cacheable memory location is lost. After the requested action has been completed, the reservation in the cacheable memory location is reset by the second process.

A method and apparatus are provided for efficiently managing limited resources is a given computer system. The system utilizes a token manager that assigns tokens to groups of associated requestors. The tokens are then utilized by the requesters to occupy the given resource. The allocation of these tokens, thus, prevents such problems as denial of service due to a lack of available resources.

The present invention provides a method, system, and computer program product for displaying images of conference call participants. A method in accordance with an embodiment of the present invention includes receiving a call from a user to join a conference call, obtaining a phone number of the user, matching the phone number to a stored graphical representation, and distributing and displaying the matching graphical representation to a predetermined set of users. A voice identification/recognition process can also be used to match the user to a stored graphical representation.

The present invention renders a triangular mesh for employment in graphical displays. The triangular mesh comprises triangle-shaped graphics primitives. The triangle-shaped graphics primitives represent a subdivided triangular shape. Each triangle-shaped graphics primitive shares defined vertices with adjoining triangle-shaped graphics primitives. These shared vertices are transmitted and employed for the rendering of the triangle-shaped graphics primitives.

A computer implemented method, data processing system, and processor are provided for managing a thermal management system. A determination is made as to whether a plurality of digital thermal sensors is faulty or functional. A power savings mode of at least one unit within the integrated circuit associated with the functional digital thermal sensor is monitored in response to at least one of the plurality of digital thermal sensors being functional. A functional digital thermal sensor is disabled in response to the at least one unit being in a power savings mode.

A computer implemented method, data processing system, and processor are provided for tracing thermal data via performance monitoring. A performance monitor is set into a tracing mode. Temperatures are sensed by a digital thermal sensor over a time period. The sensed temperatures are stored in a data structure and a trace of the sensed temperatures is graphically displayed.
摘要:
A computer implemented method, data processing system, and computer usable code are provided for generation of software thermal profiles for applications executing on a set of processors using thermal sampling. Sampling is performed of the thermal states of the set of processors for the set of workloads to create sampled information. A thermal index is then generated based on the sampled information.
摘要:
A buffer, a method, and a computer program product for DMA transfers are provided that are designed to save memory space within a local memory of a processor. The buffer is a return buffer with a portion reserved for DMA lists. A DMA controller accomplishes DMA transfers by: reading address elements from a DMA list located in the DMA list portion; reading the corresponding data from system memory; and copying the corresponding data to the return buffer portion. This buffer saves space because when the buffer begins to fill up the corresponding return data can overwrite the data in the DMA list. Accordingly, the DMA list overlays on top of the return buffer, such that the return data can destruct the DMA list and the extra storage space for the DMA list is saved.
